Hello Justice,

    I've signed up to review your article modifications for "Main Effect", but I can't seem to find them.  Will you be posting the changes to your sandbox, or should I look elsewhere? Vs2357 (talk) 02:02, 24 March 2018 (UTC)[reply]

Nice job on the modifications to the article. I appreciated your comparison of main effects with interactions and your discussion of how main effects may be used. I do have a few suggestions for improvements:

1) "The main effects of a factor are contrasts between levels of one factor averaged over all levels of another factor whilst the interactiThe main effects of a factor are 
    contrasts between levels of one factor averaged over all levels of another factor whilst the interaction effect measures differences between the simple effects of one factor 
    at different levels of the other factor which can also be said as a difference of differences."
    
    In this sentence you might put the portion about "difference of differences" in parentheses to make it more clear:  "... simple effects of one factor at different levels of the 
    other factor (this may also be called a difference of differences)."

2) "However the main effect is not much useful whenever there is an interaction effect..."

   This is usually true, but not always.  It may help to look at the discussion of this topic at https://www.theanalysisfactor.com/interpret-main-effects-interaction.

3) Your explanation of the purpose of the main effect is clear, so I don't think the last two sentences are really needed.

4) Kuhl's text is a great resource, but sometimes it's nice to read a different explanation. Is there another text you could reference so readers could have an additional resource?

You provided a good explanation of the topic. Let me know if you have any questions about the suggestions.Vs2357 (talk) 03:40, 23 April 2018 (UTC)[reply]

Hi Justice,

This is very nice material, but you need to make sure that you are not directly quoting from your source. Be sure to use your own words.
