Calculate the mean and median for the following continuous frequency distribution.
Classfi 0−10610−20820−302030−402540−501550−601060−704
To calculate mean:We first compute ∑xifi = 3010(from table provided above)Mean = ∑xifi∑fi= 301088 = 34.2To calculate median:N = 88, therefore, N2 = 44So, the median class is 30 − 40(as 44th term lies in 30−40 class)Median = L + (N2−Cf)h= 30 +( 44 − 3425)10= 34
