Small data vs. Big data : back to the basicsAhmed Banafa
Small data is data in a volume and format that makes it accessible, informative and actionable.
The Small Data Group offers the following explanation:
Small data connects people with timely, meaningful insights (derived from big data and/or “local” sources), organized and packaged – often visually – to be accessible, understandable, and actionable for everyday tasks.
Slide 2: Etymology: The etymology of the term ‘Big Data’ can be traced back to the mid-1990s, when it was first used by John Mashey to refer to handling and analysis of massive datasets. However, by 2013, ‘Big Data’ was already being declared obsolescent as a meaningful term by some, as it was too wide ranging and vague in definition (e.g. de Goes, 2013).
Side 6: Vagaries: Kitchin argues that it is velocity and these additional key characteristics that set Big Data apart and make them a “disruptive innovation – one that radically changes the nature of data and what can be done with them” (Kitchin, 2014). However, there is no one characteristic profile that all Big Data fit and they can take multiple forms.
Slide 8: Ethics: Several ethical questions have been raised about the scope of data being generated and retained; such as those concerning privacy, informed consent, and protection from harm.
These questions raise wider issues about what kinds of data should be combined and analysed, and the purposes to which the resulting information should be put.
Slide 9: Inequalities: Challenges of inequality have also been posed:
Whose data traces will be analysed? It is likely that only those who are better off will be represented (as they are more likely to use social media, etc.)
Access and use of open data is unlikely to be equally available to everyone due to existing structural inequalities (Eynon, 2013)
Slide 11: What do Big Data actually tell us? Eynon (2013) argues that Big Data is concerned with capturing and examining patterns, and tells us more about what people actually do than about what they say they do. However, this is not sufficient for all kinds of social science research. We need to understand the meanings of behaviours which cannot be inferred simply from tracking specific patterns.
In order that Big Data are used appropriately, we need to ensure understanding of what kinds of research can or cannot be carried out using them. Big Data should not be seen as [a] “technical fix” for research, but should be used to empower, support and facilitate practice and critical research.

Big data refers to large volumes of diverse data that are created quickly and in large quantities. It is characterized by 3 V's - volume, velocity, and variety. Volume refers to the large amount of data, velocity refers to the speed at which data is generated and processed, and variety refers to different types of data including structured, unstructured, and semi-structured data. Big data is generated from various sources like users, sensors, applications and requires distributed storage, processing using tools like Hadoop and MapReduce. Analyzing big data can provide competitive advantages through insights from hidden patterns, better decision making and improved business operations. Programming languages like Python, Java, R, Scala are commonly used for big data applications.
The document provides an overview of data science. It defines data science as a field that encompasses data analysis, predictive analytics, data mining, business intelligence, machine learning, and deep learning. It explains that data science uses both traditional structured data stored in databases as well as big data from various sources. The document also describes how data scientists preprocess and analyze data to gain insights into past behaviors using business intelligence and then make predictions about future behaviors.
Big data analytics (BDA) involves examining large, diverse datasets to uncover hidden patterns, correlations, trends, and insights. BDA helps organizations gain a competitive advantage by extracting insights from data to make faster, more informed decisions. It supports a 360-degree view of customers by analyzing both structured and unstructured data sources like clickstream data. Businesses can leverage techniques like machine learning, predictive analytics, and natural language processing on existing and new data sources. BDA requires close collaboration between IT, business users, and data scientists to process and analyze large datasets beyond typical storage and processing capabilities.

Big Data, NoSQL, NewSQL & The Future of Data ManagementTony Bain
It is an exciting and interesting time to be involved in data. More change of influence has occurred in the database management in the last 18 months than has occurred in the last 18 years. New technologies such as NoSQL & Hadoop and radical redesigns of existing technologies, like NewSQL , will change dramatically how we manage data moving forward.
These technologies bring with them possibilities both in terms of the scale of data retained but also in how this data can be utilized as an information asset. The ability to leverage Big Data to drive deep insights will become a key competitive advantage for many organisations in the future.
Join Tony Bain as he takes us through both the high level drivers for the changes in technology, how these are relevant to the enterprise and an overview of the possibilities a Big Data strategy can start to unlock.
This document discusses data science and the growing field of big data. It notes that data science uses scientific methods and processes to extract knowledge and insights from structured and unstructured data. It provides some key facts about the massive amount of data being generated every day from various sources like social media, internet transactions, sensors and devices. The document also discusses the differences between data science and computer science, with data science focusing more on analyzing large datasets to answer questions and find insights, while computer science focuses more on software development and engineering.
Big data comes from a variety of sources such as sensors, social media, digital pictures, purchase transactions, and cell phone GPS signals. The volume of data created each day is vast, with over 2.5 quintillion bytes created in the last two years alone. Big data has four characteristics - volume, variety, velocity and value. It refers to both the large amount of data and the different types of structured and unstructured data. This data is generated and moves around at high speeds. While big data brings value, it can be difficult to analyze and extract useful insights from due to its scale and complexity. Technologies like Hadoop, HDFS, and MapReduce help process and analyze big data across large clusters of servers in a
Abstract:
Big Data concern large-volume, complex, growing data sets with multiple, autonomous sources. With the fast development of networking, data storage, and the data collection capacity, Big Data are now rapidly expanding in all science and engineering domains, including physical, biological and biomedical sciences. This paper presents a HACE theorem that characterizes the features of the Big Data revolution, and proposes a Big Data processing model, from the data mining perspective. This data-driven model involves demand-driven aggregation of information sources, mining and analysis, user interest modeling, and security and privacy considerations. We analyze the challenging issues in the data-driven model and also in the Big Data revolution.
This document provides an overview of data science including its importance, what data scientists do, how the field has emerged, and how to become a data scientist. It notes that by 2018 the US could face shortages of people with data analytics skills.

Big data comes from a variety of sources such as sensors, social media, digital pictures, purchase transactions, and cell phone GPS signals. The volume of data created each day is vast, with 2.5 quintillion bytes created daily, 90% of which has been created in just the last two years. Big data is characterized by its volume, variety, velocity and value. It requires new tools like Hadoop and MapReduce to store and analyze data across distributed systems. When dealing with big data, once complex modeling can sometimes be replaced by simple counting techniques due to the large amount of data available. Companies are beginning to generate value from big data through new insights and business models.
Data science is a multi-disciplinary field that uses scientific methods and processes to extract knowledge and insights from large amounts of structured and unstructured data. As the amount of data in the world grows exponentially, the need for data scientists to analyze this big data and discover useful patterns will also grow dramatically. By 2025, it is estimated that there will be over 200 zettabytes of cloud data storage worldwide and data science jobs are projected to be the highest paid and most in-demand jobs of the future.

Big data refers to large and complex datasets that are difficult to analyze using traditional methods. It is characterized by high volume, velocity, and variety of data from numerous sources. Big data analytics uses tools like Hadoop and Spark to extract meaningful insights from large, unstructured datasets in real-time. This allows companies to gain valuable business insights, reduce costs, enhance customer experience, innovate products, and make faster decisions.
The document discusses the limitations of using big data to predict human behavior. While big data offers unprecedented insights into consumer actions and attitudes, predicting human behavior remains challenging due to its inconsistency, impulsiveness, and dynamic nature. Marginal gains may be possible through big data analysis, but major breakthroughs are unlikely as long as human behavior remains hard to anticipate. Managers need to thoughtfully apply big data insights and not rely on them exclusively for decision-making, given the inherent randomness in human choices and actions.
The document discusses the lack of data in healthcare, especially in rural and developing areas, which has led to major disparities between developed and developing countries. Most healthcare data is still collected manually using paper which is inefficient and error-prone. Reliable and high-quality data is needed to accurately understand healthcare issues and solve global problems, but obtaining such data remains a challenge, particularly in places where data is not readily available. Advanced analytics could help predict broader healthcare needs and guide effective responses by analyzing even small, local data samples.
Relevant insights for a manager in IndiaPrince Barai
This document provides insights for managers on finding a data scientist for their company. It recommends not specifically searching for a data scientist, as a logical person with basic data skills and a creative mindset can help the company more. The person should have basic math, programming, logical thinking, problem-solving abilities and understand key data science principles. Managers should start small with simple problems and focus on people skills rather than exclusively searching for a unicorn data scientist. The overall message is that investing time in the right person can yield better returns than persistently searching for an elusive data scientist.
The Big-Data Revolution in Healthcare Prince Barai
The healthcare industry generates huge amounts of data from patients but accessing, managing, and interpreting this data to create useful insights is challenging. Healthcare data is expected to grow from 153 exabytes in 2013 to over 2314 exabytes by 2020, a 48% annual increase. To leverage this data, the industry is transitioning from paper-based data collection to cloud-based systems that can process information faster and provide important insights. Indian healthcare managers should collect data from many sources and use new efficient technologies to analyze the data quickly before it becomes obsolete in order to improve patient care and operational efficiency.
The document summarizes key insights from an article on data analytics for leaders. It discusses two main points:
1) Thinking skills are more important than technical skills in data analytics, as data may not always be genuine and thinking is needed to evaluate the data.
2) Thinking alone is not enough; leaders must also know how to implement insights and create an organizational culture where "thinking" is not sufficient without "knowing" and applying skills. A working knowledge of data science helps leaders implement insights with confidence.
Overall, the document argues that a manager with the insights discussed around critical thinking and implementation will be able to achieve better results through data analytics.
This document provides 3 questions to consider when evaluating statistics:
1. Can you see uncertainties in the data?
2. Can you see yourself or your experiences represented in the data?
3. How was the data collected? It is important to understand the process used to gather the data as much as the data itself. Proper data collection methods help ensure statistics are trustworthy.
This document discusses predictive analysis and its key elements. It explains that predictive analysis uses past data to predict the future. The three important elements of quantitative analysis are past data, statistics, and assumptions. It notes that obtaining quality past data at a granular level can be difficult. Regression analysis is commonly used for predictive analysis to find correlations between independent variables. Assumptions help in variable selection, but some Netflix predictive models had to be retired because later internet users were substantially different, invalidating the models' assumptions. The document emphasizes the importance of using the right data, statistical model, and assumptions for accurate predictive analysis.
Swedish students scored poorly on a pre-test about global health and development issues. The document argues this was due to preconceived ideas rather than ignorance. It presents animated data visualizations showing trends over time in life expectancy, family size, income distribution, and child mortality across different regions of the world. The visualizations illustrate how countries like China, Latin America, and Africa have changed, with China focusing on better health and Latin America moving towards smaller families. It concludes that such data is not being used efficiently and that animations, interactivity, and search functions are needed to better present information about global trends.
The document discusses the importance of communicating data effectively. It states that data is worthless if not communicated, and that over 1.5 million managers are needed to take advantage of all generated data. However, results do not speak for themselves, and proper communication is needed. It provides examples of scientists like Gregor Mendel and Dr. John Gottman who achieved recognition through good data communication. While there is data everywhere, it needs to be communicated effectively to the intended audience by focusing only on relevant details. The key message is that having data is not enough - it must be communicated well to have value.
David McCandless creates beautiful data visualizations called infographics that reveal unexpected insights from complex datasets. By turning information like worldwide military spending or Facebook status updates into simple diagrams, McCandless is able to tease out unseen patterns. Good design, he suggests, is the best way to navigate information overload and change how we see the world. The document then provides examples of McCandless' infographics and discusses how visualizing data in this way can provide insights.
The document discusses characteristics of being data-driven. Some key characteristics include making decisions at the lowest level using diverse data to develop understanding, appreciating variation, and dealing with uncertainty. The essence of being data-driven is using data to make better decisions throughout an organization. Data-driven individuals conduct experiments, recognize varying decision criteria, realize decisions are not final, and work to improve skills and bring in new data.
Jer Thorp argues that data should be made more human by putting people at the center and understanding the context in which data is collected. Visualizing data creatively helps make it more relatable and gives better insights. Managers can use these insights to personalize marketing, understand customer needs in context, and connect more intimately with customers through supportive data visualization. The relationship between people and their data is important, especially regarding privacy.
How to start thinking like a Data Scientist !Prince Barai
The document provides tips for starting to think like a data scientist by forming questions about issues at work, planning what data can help answer those questions, doing analysis to address the problem, and then repeating the process. It also discusses how data insights are relevant to managers in India by helping them understand subordinates' work, make better decisions, and support business growth. Managers who utilize data analytics can help their teams and company.
This document discusses data science and data scientists. It defines data science as using scientific methods and processes to extract knowledge and insights from structured and unstructured data. Data scientists are analytical experts who use technical skills and curiosity to solve complex problems by straddling both business and IT. They have skills in mathematics, technology, and business strategy. As data has become more valuable, data scientist roles have evolved from statisticians and analysts to help organizations gain insights from large data sources. Managers should learn to identify data science talent to make their organizations more productive by adding data-driven insights.

Do People Really Know Their Fertility Intentions? Correspondence between Sel...Xiao Xu
Fertility intention data from surveys often serve as a crucial component in modeling fertility behaviors. Yet, the persistent gap between stated intentions and actual fertility decisions, coupled with the prevalence of uncertain responses, has cast doubt on the overall utility of intentions and sparked controversies about their nature. In this study, we use survey data from a representative sample of Dutch women. With the help of open-ended questions (OEQs) on fertility and Natural Language Processing (NLP) methods, we are able to conduct an in-depth analysis of fertility narratives. Specifically, we annotate the (expert) perceived fertility intentions of respondents and compare them to their self-reported intentions from the survey. Through this analysis, we aim to reveal the disparities between self-reported intentions and the narratives. Furthermore, by applying neural topic modeling methods, we could uncover which topics and characteristics are more prevalent among respondents who exhibit a significant discrepancy between their stated intentions and their probable future behavior, as reflected in their narratives.
