- This video demonstrates how to calculate the effect size (Cohen’s d) for a One-Sample T Test using SPSS and Microsoft Excel. Cohen’s d expresses the difference between the sample mean and the population mean using standard deviation units.
Although the equations confused me, it was interesting to see how you can use both SPSS and Excel together for calculating the Cohen's d and using the data from the T-test. I will remember that the strength of the Cohen's d is not affected by it being positive or negative because negative versus positive determines the direction. Cohen's d also tells you how many standard deviations lower or higher the sample mean is from the population mean. This video was helpful because I am using Cohen's d in my research paper.
Easy video to follow, I appreciate seeing SPSS and excel both. The calculations are simple and will be helpful later.
I also liked seeing the steps used in SPSS and Excel to calculate Cohen's d. I would need practice on using the equations though.
Thank you! It's so simple yet I couldn't find it anywhere!
I'm glad you found the video useful. Thanks for watching.
This was very helpful on how to calculate Cohen's d, excellent video.
Thank you so much! So helpful for nursing statistics :)
You're welcome, thank you for watching
Thank you this is so helpful, so you have a video on how to calculate Cohen’s d for independent samples t-test ?
Great video, thanks
Hello, Dr. Grande. I am a student major in psychology. I want to use this method in my paper. Could you let me know the reference for this method to demonstrate?
Flipping back and forth to both Excel and SPSS can you use just one or the other when looking for this result
Dr. Grande made another video for calculating Cohen's d using only Microsoft Excel, and I believe it is still in this playlist. I agree that flipping back and forth could be difficult. If I was not walked through these steps, I would have been confused.
how do you convert the t value calculated into a Cohen´s d for a single group?
Hi Todd. I get effect sizes of 1 with several decimal places . Would I report as 1?
Wouldn't you just repport 1.xx with two decimal places?
How would I calculate the Cohen's d for a paired sample t-test using SPSS output?
