How do you write up an interpretation of the results ? I already filled out the table, however I need help with a written format of he results of this study. Please see picture for what has to be included in the write up. Problem 6-Write-up . Your written report of the ANOVA results should include the following in a paragraph of text (i.e., NOT a bulleted list): . The name of the statistical test used The variables in the...
All work must be shown. That is, you need to show the steps and calculations you used to arrive at every answer for credit - For example, I need to see which two numbers you divided to arrive at a particular S? value, F-ratio value, etc. The "Pygmalion Effect" refers to the effect of teacher expectations on student academic achievement and performance (for the classic study on this phenomenon, see Rosenthal & Jacobson, 1968; for a more recent review of...
