    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 this is so helpful, so you have a video on how to calculate Cohen’s d for independent samples t-test ?

    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?

    how do you convert the t value calculated into a Cohen´s d for a single group?

    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.

    Hi Todd. I get effect sizes of 1 with several decimal places . Would I report as 1?

    • @aleksandraszafran350
      @aleksandraszafran350 8 ปีที่แล้ว

      Wouldn't you just repport 1.xx with two decimal places?

  • @marcinberg1728

    How would I calculate the Cohen's d for a paired sample t-test using SPSS output?
