Question

BlackTom AI · Accepted Answer

The question asks about representing the frequency distribution of quantitative data across class intervals using a bar chart.
Option 1: True. This is not the standard approach. While bar charts are great for comparing discrete categories (especially qualitative data), they are not ideal for displaying distributions over class intervals of quantitative data because they can imply gaps or ignore the continuous nature between adjacent classes.
Option 2: False. This correctly notes that a bar chart is not the typical tool for showing a frequency distribution over quantitative class intervals. Instead, a histogram is used, where the continuous quantitative data are grouped into classes and the area (or height, with equal class widths) reflects frequency or relative frequency, preserving the data's continuity across intervals. A frequency polygon is another option that connects class midpoints to illustrate the distribution, and a bar chart is generally reserved for separate categories rather than continuous intervals.
In sum, the statement as given overstates the suitability of a bar chart for this purpose and ignores the standard histogram approach used for grouped quantitative data. The common practice is to employ a histogram to visualize frequencies over class intervals, rather than a bar chart.
