If in a frequency distribution, the mean and median are 21 and 22 respectively, then its mode is approximately
22.0
20.5
25.2
24.0
Mode + 2Mean = 3 Median ⇒ Mode = 3 × 22 - 2 × 21 = 66 - 42 = 24
The mean and mode of a frequency distribution are 28 and 16 respectively. The median is
(a) 22 (b) 23.5 (c) 24 (d) 24.5
