  1. In a histogram, no space is left in between two rectangles, but in a bar diagram some space must be left between consecutive bars

  2. The width of a bar is unimportant for the purpose of comparison. The width in a histogram is as important as its height.

  3. We can have a bar diagram both for discrete and continuous variables, but the histogram is drawn only for a continuous variable.

  4. All of these

When in a frequency distribution class widths are not same we have to draw histogram then,

economics graphical representation revisiting histograms histogram histograms histograms for non-uniform class widths histograms with unequal class intervals

  1. We mark class size as width and the given frequency as length and draw the rectangle

  2. We reduce class size to minimum class size keeping the length same

  3. We find the proportionate lengths of the class corresponding to minimum width and draw the rectangle.

  4. None of these

Show answer
Correct Option: C
Explanation:

When in a frequency distribution class widths are not same we have to draw histogram then,We find the proportionate lengths of the class corresponding to minimum width and draw the rectangle.
Answer (C) We find the proportionate lengths of the class corresponding to minimum width and draw the rectangle.
