Problem 2.1.7
Textbook Question
Most Valuable Player The following Pareto chart shows the position played by the most valuable player (MVP) in the National League since 1931. How many MVPs played first base (1B)?

Verified step by step guidance1
Identify the position of interest from the problem, which is first base (1B).
Look at the bar corresponding to 1B on the Pareto chart.
Observe the height of the bar for 1B, which represents the frequency or number of MVPs who played first base.
Read the value on the vertical axis (Frequency) that aligns with the top of the 1B bar.
This value is the number of MVPs who played first base.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Bar Graph Interpretation
A bar graph displays categorical data with rectangular bars representing the frequency of each category. The height of each bar corresponds to the count or frequency, allowing easy comparison across categories. Understanding how to read the axes and bars is essential for extracting accurate information.

Frequency
Frequency refers to the number of times a particular value or category occurs in a data set. In this context, it shows how many MVPs played each position. Recognizing frequency helps quantify and compare the popularity or occurrence of different categories.

Categorical Data
Categorical data represents variables that can be divided into distinct groups or categories, such as player positions in baseball. Analyzing categorical data involves counting and comparing frequencies, often visualized with bar graphs or pie charts.
