Q 4.4. - The Practice of Statistics for AP

Question

About 1.6 million first-year students enroll in colleges and universities each year. What do they plan to study? The graph displays data on the percent of first-year students who plan to major in several discipline areas.

Would it be correct to describe this distribution as right-skewed? Why or why not?

Step-by-Step Solution

Answer

The given graph is right skewed. 

Step 1: The given information

The given graph has to be decided to describe this distribution as right-skewed or not. 

Step 2: Concept

Quantitative variables can have a wide range of values. When adjacent values are grouped together, a graph of the distribution becomes clearer. A histogram is the most frequent graph for displaying the distribution of a single quantitative variable. 

Step 3: Explanation

The majority of the graph data is displayed on the left-hand side of the histogram, but some of the big size values are exhibited on the right-hand side, indicating that the data is skewed to the right. As a result, the graph is right-skewed.
