What Is Data Analytics? Key Concepts, Skills, and Careers

Data analytics is the collection, transformation, and organisation of data to conclude, make predictions, and drive informed decision-making. 

Data analytics is often confused with data analysis. While these are related terms, they aren’t the same. Data analysis is a subcategory of data analytics that extracts meaning from data. Data analytics, as a whole, includes processes beyond analysis, such as data science (using data to theorise and forecast) and data engineering (building data systems).

Why data analytics is important and how it is used

Data is everywhere, and people use it daily, whether they realise it or not. Daily tasks such as measuring coffee beans to make your morning cup, checking the weather report before deciding what to wear, or tracking your steps throughout the day with a fitness tracker can all be forms of analysing and using data.

Data analytics is important across many industries, as many business leaders use data to make informed decisions. A sneaker manufacturer might look at sales data to determine which designs to continue and which to retire, or a healthcare administrator may look at inventory data to assess the medical supplies they should order. At Coursera, we may look at enrollment data to determine what courses to add to our offerings.

Organisations that use data to drive business strategies often find that they are more confident, proactive, and financially savvy.

Data analytics: Key concepts

There are four key types of data analytics: descriptive, diagnostic, predictive, and prescriptive. These four types of data analytics can help an organisation make data-driven decisions. At a glance, each of them tells us the following: 

• Descriptive analytics tell us what happened.

• Diagnostic analytics tell us why something happened.

• Predictive analytics tell us what will likely happen in the future.

• Prescriptive analytics tell us how to act.

People who work with data analytics will typically explore each of these four areas using the data analysis process, which includes identifying the question, collecting raw data, cleaning data, analysing data, and interpreting the results.

How to learn data analytics skills

Data analytics requires a wide range of skills to be performed effectively. According to search and enrollment data among Coursera’s community of 87 million global learners, these are the top in-demand data science skills:

• Structured query language (SQL), a programming language commonly used for databases

• Statistical programming languages, such as R and Python, which are commonly used to create advanced data analysis programs

• Machine learning, a branch of artificial intelligence that involves using algorithms to spot data patterns

• Probability and statistics to better analyse and interpret data trends

• Data management, or the practices around collecting, organising, and storing data

• Statistical visualisation, or the ability to use charts and graphs to tell a story with data

• Econometrics, or the ability to use data trends to create mathematical models that forecast future trends

While careers in data analytics require a certain amount of technical knowledge, approaching the above skills methodically—for example, by learning a little bit each day or learning from your mistakes—can help lead to mastery, and it’s never too late to get started.
