4. Example-4


1. Calculate Class and their frequency table from the following grouped data
ClassCumulative Frequency
0 - 1040
10 - 2036
20 - 3029
30 - 4016
40 - 505
50 - 600


Solution:
First we convert Cumulative frequency table to gropued frequency table

ClassCumulative Frequency
0 - 1040
10 - 2036
20 - 3029
30 - 4016
40 - 505
50 - 600

Class and their frequency table is
ClassCumulative FrequencyFrequency
0 - 10404 (= 40 - 36)
10 - 20367 (= 36 - 29)
20 - 302913 (= 29 - 16)
30 - 401611 (= 16 - 5)
40 - 5055 (= 5 - 0)
2. Calculate Class and their frequency table from the following grouped data
ClassCumulative Frequency
0 - 100
10 - 205
20 - 3016
30 - 4029
40 - 5036
50 - 6040


Solution:
First we convert Cumulative frequency table to gropued frequency table

ClassCumulative Frequency
0 - 100
10 - 205
20 - 3016
30 - 4029
40 - 5036
50 - 6040

Class and their frequency table is
ClassCumulative FrequencyFrequency
10 - 2055 (= 5 - 0)
20 - 301611 (= 16 - 5)
30 - 402913 (= 29 - 16)
40 - 50367 (= 36 - 29)
50 - 60404 (= 40 - 36)
