Which one of the following statements is not correct with reference to a histogr
Which one of the following statements is not correct with reference to a histogram?
- A. Frequency curve is obtained by joining the midpoints of the top of the adjacent rectangles with smooth curves
- B. Histogram is drawn for continuous data
- C. The height of the bar is proportional to the frequency of that class
- D. Mode of the distribution can be obtained from the histogram
Step-by-step solution
In a histogram, the area of each bar is proportional to the frequency of the class, not necessarily the height. Height is proportional to frequency density (frequency per class interval), so statement C is incorrect when class intervals are unequal. Options A, B, and D are correct.
