Assuming that the standard notations in the right hand side correspond to the cases in left hand side we have,
k: The number of treatment conditions
n: The number of scores in each treatment
N: The total number of scores in the entire study
T: The sum of scores for each treatment condition
G: The sum of all the scores in the research study
F: The F-ratio

A researcher conducts an experiment comparing three treatment conditions. The data consist of n = 34 scores for each treatment condition. a. If the researcher used an independent-measures design, then how many individuals were needed for the study and what are the df-values for the F-ratio? Explain in detail and be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all steps and all parts of all answers. b. If the researcher used...
