Calculate the mean deviation about the median of the following frequency distribution: 5 7 9 11 13 15 17 2 4 6 8 10 12 8

Explanation

We know, N = 50 Median = `(50)/2 = 25 `


So, the median Corresponding to 25 is 13


`((x),(5),(7),(9),(11),(13),(15),(17),(Total))`
`((f),(2),(4),(6),(8),(10),(12),(8),(50))`
`((cf),(2),(6),(12),(20),(30),(42),(50))`
`((d),(8),(6),(4),(2),(0),(2),(4))`
