    So, for single factor or total scale, should we just report OMEGA TOTAL?

    Thanks for the video! I have a question: I currently have an Excel file with a list of companies and their ISINs. There are also columns that show the ESG score, environmental score, social score and governance score for the years 2002 to 2023. For example, one column is called "ESG score (FY 2002)" However, I would like the columns to show only the year (2002-2023) and also add a column containing the "ESG datatype". So whether it is the esg score, environment score etc. Do you have any idea how I can implement this?

      Because it produces p values using a chi square distribution. A huge number of tests do this.

    Hi Prof. Paul Christiansen. I tried to copy what you did in 5:48 of the video wherein you typed the modelnull and model1 and you performed, "anova(modelnull,model1)." When I performed the anova function in R, this is the error message that prompted, "Error in UseMethod("anova") : no applicable method for 'anova' applied to an object of class "c('double', 'numeric')." Could you please help resolved this error message? Thank you in advance!

    Hi! Thank you for this video, it was really helpful. I was wondering if you could give me advice on how I should report my results. My research looks at Likert-Scale responses (ordinal values 1-5) on the perceived effect of 4 different compositions (/treatment group) of music. How can I find out which composition of music had the "biggest" perceived effect? I tried comparing median ranks to post-hoc results, however, many pairs did not demonstrate statistical significance though they had big difference in median ranks. Not sure if my question is clear but your advice would be very much appreciated

    Excellent, thank you very much, I learned a lot and also applied some, if I want to have a color for a certain condition in my case I mapped voting areas in the elections, if it is up to 20 percent a certain color if between 20 and 80 percent a certain color and above a certain color, I applied the code for The ballot boxes without conditions.

    • @DrPC_statistics_guides
      @DrPC_statistics_guides 6 месяцев назад

      The correlation coefficient is not compared to the p value, the correlation coefficient generates the p value. The bigger the correlation coefficient the smaller the p value
