Calculate mode from the following data :
`{:("Class Interval",30-40,40-50,50-60,60-70,70-80,80-90,90-100),("Frequency"," "3," "4," "6," "10," "6," "4," "3):}`

Text Solution

Verified by Experts


A glance at the above table reveals that model class is 60-70. The actual value of mode is `Z= l_(1)+(f_(1)-f_(0))/(2f_(1)-f_(0)-f_(2))xxi`
`=60+(10-6)/(2(10)-6-6)xx10`
`=60+(4)/(20-12)xx10`
`=60+(4)/(8)xx10`
`=60+5=65`
Mode = 65.
