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?
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.
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.
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
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

This was really straight forward - I literally completed my first meta-analysis using this... Thank you Prof K
Thanks so much! Glad you found it helpful!
You saved my life with this video professor thank you so much for the most clear explanations!!!!!
Thank you so much! I'm glad you found it helpful.
Wow! The thoroughness and simplicity of your presentation made understanding of meta analyses a piece if cake. Thank you, doc!
Thank you far laying this out so lucidly! You really have a knack for this, please make more explanatory videos 😁
Thank you so much! I'm glad you found it helpful.
you saved my research project thanks!
I'm so glad!

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

Thank you so much! I'm glad you found it helpful. I updated the video description to include a link to the source files and data sets.
Prof Kramer - can you lead me to your paper on meta-analysis, I intent to dive deep into the areas of my research. Thanks.
Thanks, professor!
Hey make more videos dad keep doing videos
Is that really your father?
Thanks, Gavin!
@@piecesofme8531 yes he is
Hi I cannot find a link to sample data sets
This is great, thanks!
Hi Professor Kramer, which is best method to calculate effect size? Pearson's r or cohen's d?
Thank you!!'
very clear！Thank you！
I cannot download the sps file, they open as text
Thank You so much!!!
Why don't you explain what data is needed to calculate an effect size?
thank you .
thank you proff
Is there a minimum number of studies to be included for a research to be called a meta-analysis?

Very cool.

He taught my stats and R module at uni. Didn't realise how big he was until now ha

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