Construct a frequency distribution for the data. Show classes, class boundries, class midpoints, frequencies, relative frequencies, and cumulative frequencies

What is the modal class?

Answer 1

Solution:

Here we have give all the calculation

Class	Boundries	Midpoints	Frequency	relative Freq.	Cumulative Freq.
1 - 25	0.5 - 25.5	13	23	0.575	23
26 -50	25.5 - 50.5	38	7	0.175	30
51 -75	50.5 - 75.5	63	1	0.025	31
76 - 100	75.5 - 100.5	88	3	0.075	34
101 - 125	100.5 - 125.5	113	2	0.05	36
126 - 150	125.5 - 150.5	138	0	0	36
151 - 175	150.5 - 175.5	163	3	0.075	39
176 - 200	175.5 - 200.5	188	1	0.025	40

Now modal class for this data is 1 - 25 because frequency for this class is maximum.
