Explanation

According to the textbook context, a bar diagram comprises a group of equispaced and equiwidth rectangular bars for each class or category of data. The text explicitly states that 'although the bars have the same width, the width of a bar is unimportant for the purpose of comparison.' This means that while the specific width chosen is arbitrary and unimportant for comparison purposes, all bars in a bar diagram must have the same (equal) width. The height of the bar is what represents the magnitude of data, not the width. This distinguishes bar diagrams from histograms, where the width of rectangles corresponds to class intervals and may vary.

Solution Steps

  1. Step 1: Identify the key statement from the context: 'Bar diagram comprises a group of equispaced and equiwidth rectangular bars for each class or category of data.'

  2. Step 2: Note that the context confirms 'although the bars have the same width' - indicating bars must be equal in width.

  3. Step 3: Conclude that the statement 'Width of bars in a bar diagram need not be equal' is False since bars must be equiwidth.
