Correlation Analysis: A Crucial Expertise for Data Analysts and Researchers

In today’s evidence based era, knowing correlation and analysis is important for every ambitious data analyst and researcher. Either correlating variables in clinical studies or working on IBM SPSS Statistics software, learning correlation analysis is vital. Through this article, we explain the basic notions of correlation analysis, including Pearson correlation, Spearman’s correlation, and correlation regression analysis. For ease of your understanding, we also provide access to our online courses for data analysts and statistics books.

What is Correlation Analysis?

Correlation analysis is a statistical technique used to determine direction of correlation and its strength between two quantitative variables. It is important to know the basics of correlation analysis, especially while using correlation analysis calculators or applying correlation regression statistics.

There are two primary types of correlation analysis:

• Pearson correlation: Used for quantitative and normally distributed data. The Pearson correlation coefficient quantifies the strength of correlation.
• Spearman’s correlation: Used for ordinal or non-normal data. It applies Spearman rank, and is calculated as the Spearman rank correlation coefficient or Spearman rank coefficient.

Details about both can be well understood in our selected clinical research courses, and are a part of basic introduction to statistics.
