How to calculate Pearson's r correlation coefficient Warning: I calculated the degrees of freedom (df) incorrectly. The N is 7, not 14. I counted the number of scores (which is typical in other calculations), instead of the number of cases. In this example, the df is indeed 5, meaning the critical value is 0.669, which is greater than the ...

This video shows how to make a correlation matrix in Excel, including how to calculate each correlation.

Introduction The most commonly used techniques for investigating the relationship between two quantitative variables are correlation and linear regression. Correlation quantifies the strength of the linear relationship between a pair of variables, whereas regression expresses the relationship in the form of an equation. For example, in patients ...

In this video, I show you how to calculate Spearman's rank correlation value and also explain what the value means. Note that the value of correlation is always between 1 and 0, and the null hypothesis is always "there is no correlation between two data sets"

Before you can find the correlation coefficient on your calculator, you MUST turn diagnostics on. After this, you just use the linear regression menu. Update 2015: On many of the new TI calculators you might have a menu come up and ask about FreqList. You should leave this blank for this calculation, so delete anything there!

Use the Spearman Rank Correlation Coefficient (R) to measure the relationship between two variables where one or both is not normally distributed. This is a non-parametric ranks based test. Note: There are no ties in the data used in this video. If your data has ties you should consider using a different test (eg Kendall's tau). Made with GoPro.

This video covers how to calculate the correlation coefficient (Pearson’s r) by hand and how to interpret the results. Here we use the 'definitional formula' for calculating the correlation, as it is the easier of the two methods. It also makes more sense intuitively than the computational approach to calculating the correlation coefficient ...

With the help of correlation analysis, the linear relationship between variables can be examined. The strength of the correlation is determined by the correlation coefficient, which varies from -1 to +1. This means that correlation analyses can be used to make a statement about the strength and direction of the relationship between two ...
