Question

a circle graph was used to show the distribution of incomes in a neighborhood. the largest section, representing 40% of the circle graph, is labeled $45,000 to $55,000. if this segment represents the most common income range in the neighborhood, which measure of central tendency does it correspond to? mode mean median range

Explanation:

Step1: Recall definitions of measures

• Mode: The most common value (or range) in a dataset.
• Mean: Average of all values.
• Median: Middle value when data is ordered.
• Range: Difference between max and min.

Step2: Analyze the problem

The segment represents the "most common income range". The mode is about the most common (frequent) value/range. Mean is average, median is middle, range is spread. So the most common range corresponds to mode.

Answer:

mode
