Many adolescent boys aspire to be professional athletes. The paper "Why Adolescent Boys Dream of Becoming Professional Athletes" (Psychological Reports [1999]: 1075-1085) examined some of the reasons. Each boy in a sample of teenage boys was asked the following question: "Previous studies have shown that more teenage boys say that they are considering becoming professional athletes than any other occupation. In your opinion, why do these boys want to become professional athletes?" The resulting data are shown in the following table: $$ \begin{array}{lc} \text { Response } & \text { Frequency } \\ \hline \text { Fame and celebrity } & 94 \\ \text { Money } & 56 \\ \text { Attract women } & 29 \end{array} $$ $$ \begin{array}{lc} \text { Response } & \text { Frequency } \\ \hline \text { Like sports } & 27 \\ \text { Easy life } & 24 \\ \text { Don't need an education } & 19 \\ \text { Other } & 19 \\ & \\ \hline \end{array} $$ Construct a bar chart to display these data.

Step by step solution

01

Understand the data

First, it's important to understand the data. We have 8 different responses that teenage boys gave when asked why they want to become professional athletes, with the number of boys who gave each response.

02

Organize the data

Next, organize the data for easy reference. The responses will be displayed on the x-axis, and the frequencies will be displayed on the y-axis. The responses include 'Fame and celebrity', 'Money', 'Attract women', 'Like sports', 'Easy life', 'Don't need an education', and 'Other'.

03

Plot the data

Now, plot the data on the chart. For example, plot a bar that represents 'Fame and celebrity' which reaches up to 94 on the y-axis, because the frequency for 'Fame and celebrity' is 94. Repeat this process for the rest of the data points.

04

Label the chart

After plotting the data, provide a title for the chart, label the x-axis with 'Reasons for wanting to become professional athletes', and the y-axis with 'Number of responses'.

05

Review the chart

Finally, review the chart for accuracy. Ensure that all bars are correctly plotted according to their frequencies, and all labels are clear and accurate.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Bar Chart

A bar chart is a great way to visually represent data, allowing you to see differences between categories at a glance. In this case, the data represents the reasons teenage boys aspire to become professional athletes. Each reason given by the boys serves as a category on the x-axis. On the y-axis, the frequencies or number of boys who gave each response is displayed.

To create the bar chart, you first need to list all responses like this:

• 'Fame and celebrity'
• 'Money'
• 'Attract women'
• 'Like sports'
• 'Easy life'
• 'Don't need an education'
• 'Other'

Each of these responses will have a corresponding bar on the chart. The height of each bar will reflect the data value or frequency, such as 94 for 'Fame and celebrity'.
Each bar is parallel and spaced out evenly to ensure clarity. Labels should be clear and concise, with the chart’s title indicating the overall theme. This visualization process helps in promptly interpreting the survey data by highlighting which responses were most frequent among the boys.

Data Interpretation

Interpreting data from a bar chart involves analyzing the visual elements to draw conclusions. With this exercise, the most immediate insight is which reasons for wanting to become a professional athlete are the most common among the surveyed boys.

To interpret the bar chart effectively:

• Begin by observing which bar is the tallest, indicating the most common reason.
• Notice the other bars' heights relative to the tallest. This helps assess the popularity of each reason comparatively.
• Pay attention to any standout patterns, such as many boys attributing their aspirations to fame or financial reasons.

From this analysis, one might conclude that fame and financial gain are the driving forces behind these aspirations. By looking closer at the "Other" category, you can explore less commonly stated reasons, offering nuanced insights into the motivation of these individuals. Ultimately, interpreting the chart allows educators and psychologists to gather valuable information about these societal influences.

Survey Analysis

Survey analysis is crucial for understanding the collected data and making data-driven decisions or generalizations. The survey in this exercise asks boys why they want to become professional athletes, with the answers analyzed and presented on the bar chart.

Analyzing surveys involves:

• Collecting responses across a diverse sample to ensure reliability.
• Categorizing responses to facilitate visual representation and analysis.
• Reviewing data for anomalies or outliers that may affect results.

When reviewing this specific survey data, it's essential to ask what these motivations reveal about adolescent priorities and perceptions. Recognizing the emphasis on fame or financial gain might suggest cultural or media influences.
Additionally, by identifying the prevalence of certain responses, educators can tailor their approach in helping students distinguish between dreams and realistic career options. Proper survey analysis, combined with visualization through charts, enriches understanding and informs cultural or educational policies.
