The world around you is run by numbers. From the latest political poll to the national census, numbers paint a valuable picture. By analyzing numbers, we learn how people think, act, and function. You may have seen terms like data analysis, business analytics, and data science before, but you can learn what they truly mean through data analytics courses.
Simply put, data analysis is the process of analyzing the world around us using raw data. Data analysts extract information from data in numerous ways. For example, techniques like data visualization quite literally allow analysts to form a picture of what a business is doing right and what it could improve.
But how can you begin to analyze data on such a large scale? Lucky for you, there is a surplus of options to help you become more familiar with data analytics, including some free online data analytics courses.
Getting Familiar With the World of Data Analysis Tools
Before we look into data analytics courses, there are some tools you will need to make the most of your general data analytics education. Below are some skills you’ll need to succeed in data analytics.
Data analysis deals heavily with numbers. While you do not need to have a detailed understanding of trigonometry or calculus, you will still need to have a firm grasp on mathematics and its concepts.
Having a deep knowledge of statistics is arguably the most useful skill to have if you wish to pursue data analytics. Knowing how different pieces of data are collected and from where is the backbone of the data analysis process. This means you should be comfortable with graphs, charts, regressions, sample sizes, and other data analysis concepts.
To effectively analyze real-world data, you need to be able to think critically. This means you can look at one aspect of a study and extrapolate deeper meaning behind it.
Knowing how to program is a huge bonus, especially in the world of data analytics. There are plenty of different coding languages you may choose to learn, like Python, C++, Java, and more.
Learning Data Analytics Terminology
The world of data analytics is rife with different technological terms you need to get familiar with. This is crucial if you plan on enrolling in data analytics courses. Below are some concepts that make up the most critical facets of data analytics.
Big data refers to the concept of an amount of data that is so large that it defies measurement by traditional methods. However, it has now taken on another meaning.
In the modern sense, it refers to the process of predictive analysis and measuring users’ behaviors in a piece of software. Big data relies a lot on inference and mathematics.
Machine learning is the process of individual machines and algorithms learning through experience, the way humans do. Data scientists use programming languages to equip machines to learn from data all on their own.
