Which of the following numbers represents the [tex]F[/tex] score in Dr. Omar's results write-up?

A. [tex]f(4, 220) = .72[/tex]
B. [tex]p = .03[/tex]
C. [tex]\eta^2 = .[/tex]
D. [tex]220[/tex]

Answer :

In Dr. Omar's results, the F score is explicitly mentioned in option a as f(4, 220) = .72, where 'f' represents the F statistic and the numbers in parentheses are degrees of freedom for the model and error.The correct answer is option A

The F score in statistical analyses, such as an ANOVA (Analysis of Variance) or regression, refers to the test statistic used to determine whether significant differences exist between the means of groups or the prediction error of the model. When we discuss Dr. Omar's results, it seems like we are referring to the output of such an analysis. The options provided are various statistical outcomes, but the F score is explicitly mentioned in option a as f(4, 220) = .72. Here, 'f' stands for the F statistic, and the numbers in the parentheses represent the degrees of freedom for the model and error, respectively.

A p-value, such as b (p = .03), tells us the probability of observing a test statistic as extreme as, or more extreme than, the one observed if the null hypothesis is true. The eta squared value in option c (eta² = .) is a measure of effect size for ANOVA. Finally, option d (220) likely represents the total sample size or degrees of freedom but is not the F score itself.The correct answer is option A
