Identify the median class.
Farm size | 20−50 | 50−80 | 80−110 | 110−140 | 140−170 |
Rooms | 4 | 8 | 12 | 16 | 20 |
To find the median class:
First add the total number of frequencies.
Here, f=60
=(Totalnumberoffrequency)2
=(60)/2=30
Hence, the value 30 lies in the class interval 110-140 from the cummulative frequency table.
