Which of the following cannot be determined graphically
(A) mean
(B) median
(C) mode
(D) None of these
mean
Explanation for the correct option:
Option (A): Determine the base of a pyramid.
The mean is the total of a subject's values divided by the number of values. A mean is an excellent approach for determining a value's central tendency.
Therefore, the mean cannot be determined graphically.
Hence, option (A) is correct.
Explanation for the incorrect options:
Option (B), (C), and (D): By observing the data, the median and mode are computed. So, if the data are given in graphical representation, it is easy to determine the values of the median and mode by observing the graph.
Therefore, the median and mode can be determined graphically.
Therefore, options (B), (C), and (D) are incorrect.
Hence, option (A) is correct.
