Question

a professor records the following final grades in one course. construct a frequency table for the grades
a a a b b b b b b b b c
c c c c c c c d d d d f

complete the table.
(type an integer or decimal rounded to the nearest tenth as needed.)
grade frequency relative frequency cumulative frequency
a 3 12.5 % 3
b 8 33.3 % 11
c 8 33.3 % 19
d 4 16.7 % 23
f 1 4.2 % 24
total \square 1 = 100% \square

Explanation:

Step1: Calculate total frequency

Add up all the individual frequencies: \(3 + 8+8 + 4+1\).

$$3+8 + 8+4+1=24$$

Step2: Calculate total cumulative frequency

The cumulative frequency for the last grade (F) is the total number of data points. Since we have already found the total number of data points (grades) is \(24\), the total cumulative frequency is also \(24\).

Answer:

Total (Frequency): \(24\)
Total (Cumulative frequency): \(24\)
