Sometimes the most difficult part of starting a research study and/or consulting project is finding the appropriate measures. For this reason, I continuously update the List of Commonly Used Scales section of my
Statistics Help page. Prior support has been provided for each of the scales listed, meaning that they are appropriate for
applications in both research and practice.
Need help with performing statistics in Excel? Many people do! For this reason, I have
created a section of my website dedicated to guides on basic statistical analyses in Excel.
If you need help with a particular analysis that currently does not have a guide, feel free to email me at MHoward@SouthAlabama.edu.
I may have time to make you a guide!
Need help with calculating statistics in SPSS? I have that covered, too! Click on the picture to go to a section of my website dedicated to guides on basic statistical analyses in SPSS. If you need help with a particular analysis, email me at MHoward@SouthAlabama.edu.
I am always happy to help!
Need help with statistics in R? Believe it or not, I have a few pages on that too! Click on the picture to go to several help pages on basic statistical analyses in R. If you need help with any of the listed analyses, or even some that are not listed, email me at MHoward@SouthAlabama.edu.
After making guides on SPSS, Excel, and R, I told myself that I wasn’t going to make more for other programs. . .but then I discovered Jamovi! It is very intuitive, easy to use, and – perhaps most importantly – free! No coding required, but these guides can help you figure out the buttons. If you need help, please email at MHoward@SouthAlabama.edu.
Authors are often interested
in the mediation of two
sequential variables between a predictor and an outcome. Surprisingly, very few statistical programs exist which can statistically analyze a serial mediation /
sequential mediation. In two blog posts, I provide an overview of the logic behind serial mediation / sequential mediation, and I supply an easy-to-use excel
calculator that calculates a sobel test for the significance of the mediation.
