Question

mat 102: test - general math
24 which of the following types of charts provide a rough estimate of actual amounts?

• histogram
• pictograph
• bar graph
• scatter plot

Explanation:

To determine which chart provides a rough estimate of actual amounts, we analyze each option:

• Histogram: Used to represent the distribution of numerical data by showing the frequency of data within intervals. It's more about distribution than estimating actual amounts.
• Pictograph: Uses pictures or symbols to represent data. Each symbol can represent a certain quantity, so it can give a rough estimate of actual amounts as the number of symbols can be counted and multiplied by the value each symbol represents.
• Bar graph: Displays data with rectangular bars, where the length of each bar is proportional to the value it represents. It shows exact or relatively precise comparisons, not a rough estimate.
• Scatter plot: Shows the relationship between two variables as individual data points. It's for identifying trends or correlations, not estimating amounts.

So, the pictograph is the one that provides a rough estimate of actual amounts.

Answer:

B. Pictograph
