Vedclass · Answer

(A) Statement $(1)$ is true: The mode of a grouped frequency distribution can be determined graphically using a histogram.Statement $(2)$ is true: The median is affected by the change of scale. If each observation is multiplied by a constant $k$,the median is also multiplied by $k$.Statement $(3)$ is false: Variance is independent of the change of origin,but it is $NOT$ independent of the change of scale. If each observation is multiplied by $k$,the variance becomes $k^2$ times the original variance.Therefore,statements $(1)$ and $(2)$ are true.

Determine which of the following statements is true: $(1)$ The mode can be calculated using a histogram. $(2)$ The median is not independent of the change of scale. $(3)$ Variance is independent of the change of origin and scale.
