Question

Which is false?
(a) If n is odd, then $\mathrm{median}=\mathrm{value}\mathrm{of}\left(\frac{n+1}{2}\right)\mathrm{th}$ item.
(b) If n is even, then $\mathrm{median}=\frac{1}{2}\times \left\{\mathrm{value}\mathrm{of}\frac{n}{2}\mathrm{th}\mathrm{item}+\mathrm{value}\mathrm{of}\left(\frac{n}{2}+1\right)\mathrm{th}\mathrm{item}\right\}$.
(c) Mode is the item which occurs most often.
(d) $\mathrm{Mode}=\frac{1}{2}(\mathrm{mean}+\mathrm{median})$.

Answer 1

(a) True
(b) True
(c) True
(d) False
Correct formula for mode:
Mode = 3(Median) $-$ 2(Mean)
