Cohen’s d Effect Size in Excel

This video shows Dr. Evan Matthews explaining how to calculate a Cohen's d effect size that would accompany a t-test comparison. In this video this is done within an Excel spreadsheet. This video is part of a playlist of videos showing how to set up a large research spreadsheet.
Cohen's d Formula for Excel Used in Video:
=ABS([Group1Average]-[Group2Average])/SQRT(((([Group1SD]*[Group1SD])+( [Group2SD]*[Group2SD]))/2))
Cohen's d Effect Size Interpretation
A value of 0.2 represents a small effect size.
A value of 0.5 represents a medium effect size.
A value of 0.8 represents a large effect size.
