(a) Mode can be computed from histogram.
(b) Median is not independent of change of scale.
(c) Variance is independent of change of origin and scale.
Which of these is/are correct?

• A. only (a)
• B. only (b)
• C. only (a) and (b)
• D. (a), (b) and (c)

Answer 1

Answer: (C)

only (a) and (b)

(a) Tallest bar in histrogram could be used to calculate mode.

(b) Median will be changed if scale is changed

$\therefore$ Median depends on scale.

(c) Variance also changes if origin and scale are changed.
