Why is it Called Data Science?

The term “Data Science” has been around for a while, but it has only recently become a buzzword. So why is it called Data Science?

This is a multi-disciplinary field that uses scientific methods, processes, and systems to extract knowledge and insights from data. The term “Data Science” was first coined by Peter Naur in the 1960s, but it wasn’t popularized until the 1990s. It is sometimes also called “Big Data” or “Machine Learning”, but it is really its own field. This field encompasses everything from cleaning and exploring data, to building models and algorithms, to deploying those models into production.

Who is the Father of Data Science?

In 1996, William S. Cleveland published “Data Science: An Overview”, in which he defined this field as “a multi-disciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from many structural and unstructured data”.

Since then, the term “Data Science” has been used in a variety of ways, but Cleveland is generally credited with coining the term and defining its key components.

There is no one father of Data Science. It is a relatively new field, and as such, it is still evolving. However, there are a few key figures that have been instrumental in its development. One such figure is computer scientist John McCarthy, who coined the term “artificial intelligence” in 1955. Another important figure is mathematician Claude Shannon, who is also considered the father of information theory.

What Skills Do We Need For Data Science?

There is no one-size-fits-all answer to this question, as the skills needed for Data Scientists vary depending on the specific field or industry. However, some general skills that are often required for the job roles in this field include strong analytical and mathematical abilities, programming skills, and the ability to effectively communicate complex technical concepts to non-technical audiences. Additionally, since Data Scientists frequently involve working with large datasets, experience with big data platforms such as Hadoop or Spark can also be beneficial.

What are the 4 Major Components Of Data Science?

There are four major components of Data Science: Statistics, Computer Science, Mathematics, and Programming. This field is all about extracting insights from data, and these four components work together to make that happen. Statisticians develop the models that help us understand the data, computer scientists build the algorithms that power those models, mathematicians ensure that the models are accurate, and also domain experts provide the real-world knowledge that ensures the models are relevant.

Different Types of Data that Data Science can Analyze:

The data the Data Science can analyze can be classified into majorly four categories:

  • Nominal data
  • Ordinal data
  • Discrete data
  • Continuous data

Now, let’s understand them in detail

  • Nominal Data

Nominal data is one of the types of qualitative information which labels the variables without providing the numerical value. Nominal data is also called the nominal scale. It cannot be ordered and measured. But sometimes, the data can be qualitative and quantitative. Examples of nominal data are letters, symbols, words, gender etc.

  • Ordinal Data

A data variable that follows an ordinal order is called a numerical ordinal variable. The major characteristic of this kind is that the difference between the data values is not determined. This type of data is more common in surveys, finance, economics, questionnaires, and other disciplines.

  • Discrete Data

Discrete data can take only discrete values. Discrete information contains only a finite number of possible values. Those values cannot be subdivided meaningfully. Here, things can be counted in whole numbers.

  • Continuous Data

Continuous data is data that can be calculated. It has an infinite number of probable values that can be selected within a given specific range.

How to Get Started with Learning Data Science?

There is no one-size-fits-all answer to this question, as the best way to start learning this field will vary depending on your prior experience and knowledge. However, some good resources to get started with include online courses, books, and articles from experienced data scientists. You can also find helpful communities and forums online where you can ask questions and get advice from more experienced data scientists.
