Question

The cumulative relative frequency table for a set of data is shown below.

What is the missing cumulative relative frequency?

DATE VALUE    RELATIVE FREQUNCY    CUMALATIVE RELATIVE FREQUENCY

1 0.35    0.35

2 0.25    MSSING

3    0.15 0.75

4 0.25    1.00

Answer 1

Solution:

Given:

DATE VALUE	RELATIVE FREQUENCY	CUMULATIVE RELATIVE FREQUENCY
1	0.35	0.35
2	0.25	MISSING
3	0.15	0.75
4	0.25	1

We have to find  the missing cumulative relative frequency.

For finding cumulative relative frequency, we add relative frequencies from top to bottom.

DATE VALUE	RELATIVE FREQUENCY	CALCULATIONS	CUMULATIVE RELATIVE FREQUENCY
1	0.35	0.35	0.35
2	0.25	=0.35+0.25 = 0.60	0.60
3	0.15	=0.60+0.15 = 0.75	0.75
4	0.25	=0.75 +0.25 = 1.00	1

Thus   the missing cumulative relative frequency = 0.60
