Question

which of the following is not true about statistical graphs? choose the correct answer below. a. they utilize areas or volumes for data that are one - dimensional in nature. b. similar graphs can be constructed in order to compare data sets. c. they can be used to identify extreme data values. d. they can be used to consider the overall shape of the distribution.

Explanation:

• Option A: Statistical graphs should represent data appropriately. One - dimensional data (like a single variable's values) should be represented with one - dimensional visual elements (e.g., lengths in a bar graph for a single - variable count). Using areas or volumes for one - dimensional data can be misleading (e.g., a 2D or 3D graph for a 1D variable may exaggerate differences).
• Option B: It is true that we can construct similar graphs (e.g., two bar graphs with the same scale) to compare different data sets.
• Option C: Statistical graphs (like box - plots, dot - plots) can easily show extreme data values (outliers).
• Option D: Graphs like histograms can be used to analyze the overall shape of the data distribution (e.g., symmetric, skewed).

Answer:

A. They utilize areas or volumes for data that are one - dimensional in nature.
