Cumulative Frequency Distribution

The following frequency distribution table shows the number of mango trees in a grove, their yield of mangoes and also the cumulative frequency. Complete the following activity to find the median of the data. Here, total of frequencies N=250. (N)/(2)=(250)/(2)=125 The cumulative frequency which is just greater than 125 is square :. the corresponding class square is the median class. L=150,f=90,cf=square,h=50 Median =L+[(square)/(f)]xxh =150+[(square)/(90)]xx50 =150+(square)/(90)xx50~~184.4 The median of the data is 184.4 mangoes.
