A researcher conducts an independent -measures research study and obtains t= 2.070 with df = 28.
a. How many individuals participated in the entire research study?
b. Using a two-tailed test with α = .05, is there a significant difference between the two treatment conditions?
c. Compute r2 to measure the percentage of variance accounted for by the treatment effect.
A 'good' correlation is data-context driven. For example, I did a project correlating sales volume per state and customer demographics (pretty 'hard' data) and got a .92 correlation.
