Imagine you are in charge of reviewing applications for your academic institution. As a preliminary measure, you want to review only the top 25% of applicants on the basis of standardized test scores. How does calculating the z-score provide additional information regarding how each subject did overall? Provide specific examples of how you would use the information and interpret the scores.
To get the top 25% you must obtain all those with score over 0.6745 and the next step we must get the z scores from the highest to the lowest to obtain the best results from the averafe scores and the standard deviation and calculate the z score.This must be done for each one individually and after that steps we must compare the z scores to rank the scores and line up the z score from the high scores to the lowest scores.
