MEAN =>
CLASS FREQUENCY X1 FIXI
0-50 2 25 50
50-100 3 75 225
100-150 5 125 625
150-200 6 175 1050
200-250 5 225 1125
250-300 3 275 825
300-350 1 325 325
TOTAL :- 25 4225
MEAN = ∑fixi/∑fi
==> 4225/25
==> 169
mean = 169
MEDIAN ==>
CLASS FREQUENCY CF
0-50 2 2
50-100 3 5
100-150 5 10
150-200 6 16
200-250 5 21
250-300 3 24
300-350 1 25
MEDIAN = L+(N/2-CF)/F*H
==> L = 150 ; N/2 = 25/2 ==> 12.5 ; CF = 10 ; F = 6 ; H = 50
==> 150+(12.5-10)/6×50
==> 150+ 2.5/6× 50
==> 150+20.83
==> 170.83
MEDIAN = 170.83
MODE ==>
CLASS FREQUENCY
0-50 2
50-100 3
100-150 5
150-200 6
200-250 5
250-300 3
300-350 1
MODE = L+(F1-F0/F1-F0-F2)×H
==> L = 150 ; F1 = 6 , F2 = 5; F0 = 5 ; H = 50
==> 150+(6-5)/12-5-5 × 50
==> 150+ 1/2× 50
==> 150+ 25
