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!

Learn how to use the CORREL function and to manually calculate the correlation coefficient (r) in Excel 2010. This allows you to examine is there is a statistical correlation between two variables. Please note: Correlation is NOT causation!

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 ...

The Spearman correlation tests two variables for a monotonic relationship (can be linear or not). In the run-up to an empirical study or data collection for the Spearman correlation, the necessary sample size must be determined, for example using SPSS. The minimum sample size depends on one- or two-sided testing, the assumed effect (aka ...

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.
