Chapter 2: Q. 59 (page 136)

Describe the relationship between the mode and the median of this distribution.

Short Answer

Expert verified

The data distribution is symmetric becausemedian=mode

Step by step solution

01

content Introduction

The mean is less than the median, which is frequently less than the mode, if the data distribution is skewed to the left. If the distribution of data is skewed to the right, the mode is generally less than the median, which is less than the mean. The mode = the median = the mean if the data distribution is symmetric.

02

Content Explanation

The median is calculated using the below formula:

Median=N+12thterm

from the above table, N=21

Therefore,

Median=(21+12)thtermMedian=11thterm

Cumulative frequency 11thlies in x=5

The mode is one that has a maximum frequency.

Therefore, the mode is5.

The University of California has two criteria used to set admission standards for freshmen to be admitted to a college in the UC system:

a. Students' GPAs and scores on standardized tests (SATs and ACTs) are entered into a formula that calculates an "admissions index" score. The admissions index score is used to set eligibility standards intended to meet the goal of admitting the top 12%of high school students in the state. In this context, what percentile does the top 12%represent?

b. Students whoseGPAs are at or above the 96th percentile of all students at their high school are eligible (called eligible in the local context), even if they are not in the top 12%of all students in the state. What percentage of students from each high school are "eligible in the local context"?
