a researcher reports an F-ratio with df=3,36 from an idependent-measure research study.
a-how many treatment condition were compared in the study?
b-what was the total number of participant in the study

statistic-ANOVA
4 and 40
To answer both questions, we need to understand the degrees of freedom (df) associated with the F-ratio. In the context of a one-way independent-measures research study, the F-ratio is calculated using two sets of degrees of freedom: the degrees of freedom for the numerator (df numerator) and the degrees of freedom for the denominator (df denominator).
a) The df numerator represents the number of treatment conditions minus 1. In this case, the df numerator is 3-1 = 2. So, two treatment conditions were compared in the study.
b) The df denominator represents the total number of participants minus the number of treatment conditions. In this case, the df denominator is 36 - 3 = 33. So, the total number of participants in the study was 33.
