Question 25, 3.4.19 HW Score: 49.46%, 16.82 of 34 Part 2 of 3 points Points: 0 of 1

The following graph is an ogive of a standardized test's (a) Find and interpret the percentile rank of a test scores. The vertical axis in an ogive is the cumulative relative frequency and can also be interpreted as a percentile. Complete parts a through c. score with a value of 130

A test score of 130 corresponds to the 50th percentile rank since this percentage of test scores are less than or equal to a test score with a value of 130. (b) Find and interpret the percentile rank of a test score with a value of 140.

A test score of 140 corresponds to the percentile rank since this percentage of test scores are a test score with a value of 140.

Transcript text: Question 25, 3.4.19 HW Score: $49.46 \%, 16.82$ of 34 Part 2 of 3 points Points: 0 of 1 The following graph is an ogive of a standardized test's (a) Find and interpret the percentile rank of a test scores. The vertical axis in an ogive is the cumulative relative frequency and can also be interpreted as a percentile. Complete parts a through c. score with a value of 130 A test score of 130 corresponds to the $50^{\top}$ th percentile rank since this percentage of test scores are less than or equal to a test score with a value of 130 . (b) Find and interpret the percentile rank of a test score with a value of 140 . A test score of 140 corresponds to the $\square$ percentile rank since this percentage of test scores are $\square$ a test score with a value of 140.

Solution

Solution Steps

Step 1: Identify the Percentile Rank of a Test Score of 130

Locate the test score of 130 on the x-axis of the graph.
Move vertically from the score of 130 until you intersect the ogive curve.
From the intersection point, move horizontally to the y-axis to find the corresponding percentile rank.

Step 2: Interpret the Percentile Rank of a Test Score of 130

The percentile rank found in Step 1 represents the percentage of test scores that are less than or equal to 130.
According to the graph, a test score of 130 corresponds to the 50th percentile rank.

Step 3: Identify the Percentile Rank of a Test Score of 140

Locate the test score of 140 on the x-axis of the graph.
Move vertically from the score of 140 until you intersect the ogive curve.
From the intersection point, move horizontally to the y-axis to find the corresponding percentile rank.
