    This was really straight forward - I literally completed my first meta-analysis using this... Thank you Prof K

    Thank you for this very clear step-by-step guide on conducting a meta-analysis. This is way more clearly explained than my professor tried to. It's too bad you did your analysis in SPSS, since R is way more generalized nowadays.

      Thank you so much! I much prefer R to SPSS. Perhaps I will record an R version in the future.

    Hello! Thankyou for the wonderful explanation. I just had a query. Is it possible to compare the effect sizes of two different variables with each other?

    Hi! Thank you very much for this presentation. I'm doing a meta-analysis on psychological contracts as my master thesis (first time doing anything like this). I'm wondering if you know how to use the Hunter Schmidt syntax file provided by Field and Gillett? I'm running into errors when trying to use it :)

    Dr. Kramer, thank you kindly for a brilliant lecture on the basic of MA. It has been really helpful. I tried to find the supporting material on Canvas, as you mentioned in your lecture, but was not successful. Would you be kind and share the link of the repository where I could find the spreadsheets and scripts for both R and SPPS for mac. It would be very much appreciated. Thank you in advance for considering my request.

    Is there a minimum number of studies to be included for a research to be called a meta-analysis?

    • @professorkramer5937
      @professorkramer5937  4 года назад +3

      Technically, the minimum is 2. However, the full answer is more detailed based on your study. You may find this link helpful: www.researchgate.net/post/Is_there_any_minimum_number_for_studies_that_should_be_included_in_meta-analysis

      Jackson and Turner recommend at least 5. See: Jackson, D., & Turner, R. (2017). Power analysis for random‐effects meta‐analysis. Research Synthesis Methods, 8(3), 290-302. doi.org/10.1002/jrsm.1240

    Why don't you explain what data is needed to calculate an effect size?

    I am sorry, but sometimes it is really hard to get what you say because you talk too fast, you mumble sometimes and you mention the references that are not on the slide, so it is hard to follow what you are referencing too... could not understand anything from the main part where you compare the fixed and random effects model

      Try customizing the video speed. I set it at 0.8x and it worked great with captions.
