Question
The frequency distribution shows the average seasonal rainfall in California measured in inches
Please complete the chart (frequency and cumulative relative frequency) CRF to two decimal points
Rainfall Frequency Cumulative Relative Frequency
0 -9.99 2
10 – 19.99 25
20 - 29.99 0.88
30 -30.99 0.98
40 – 40.99 1.00
Total 50
I would like a clear understanding of where the values come from to complete this chart. I have seen a couple of answers that do not clearly explain how the missing values are generated (Formulas).
Explanation / Answer
Solution :
Rainfall Frequency Cumulative Relative Frequency
0 -9.99 2 2 / 50 = 0.04
10 – 19.99 25 0.04 + 25/50 = 0.04 + 0.50 = 0.54
20 - 29.99 17 17 / 50 = 0.34 + 0.54 = 0.88
30 -30.99 0.98 3 3 / 50 = 0.06 + 0.88 = 0.94
40 – 40.99 3 3 / 50 = 0.06 + 0.94 = 1.00
Total 50
