What Are Data Science Course Online Topics?

Data science courses’ curriculums vary depending on what you choose to focus on. Some data science courses focus on an overview. In contrast, others consist of more in-depth coverage of subcategories within the field. An in-depth data science course would likely cover more than one subdivision, while data science short courses typically focus on only one, or perhaps two, subdivisions.

The common topics included in data science courses curriculums cover:

Statistics — deals with collecting and analyzing numerical data in order to draw usable conclusions from it. This subdivision includes probability (i.e., using data to predict the likelihood of something).
Calculus — the study of rate of change that allows for analysis of quantitative models of change in order to infer consequences from them.
Linear algebra — a branch of mathematics that deals with data.
Programming — focuses on writing code; this is often used to automate data processing.
Machine learning — sometimes relates to artificial intelligence (i.e., the science of engineering intelligent machines). This niche of data science teaches computers to program themselves for specific tasks, and this subdivision includes deep learning.
Data mining — analyzing data to extract important and relevant information.
Data visualization — the representation of data in images or charts.
