Chapter 2: Q. 28 (page 132)

On an exam, would it be more desirable to earn a grade with a high or low percentile? Explain

Short Answer

Expert verified

A high percentile would be more desirable because higher percentiles correspond to higher grades on the exam.

Step by step solution

01

Definition

In statistics, the percentiles are the partition values. Percentile divides the entire data into 100 equal parts. The 50th percentiles denotes the median and below this value lies 50%of data. Similarly 60thpercentile will have 60% of data below it.

02

Explanation

To find the percentiles in the individual series we need to arrange the data in ascending order first and then we have to use the below formula to find the percentile value.

kthpercentile=k(N+1)100thitem

In an examination, the high percentiles correspond to the highest grades on the exam.
