Following is the list of letter grades for students in an algebra class: A, B, F, A, C, C, A, B, D, F, D, A, A, B, C, F, B, D, C, A, A, A, F, B, C, A, C. Construct a frequency distribution for these data.
To find: To construct a frequency distribution for the below list of letter grades for students in an algebra class:
Answer to Problem 1CQ
Frequency distribution is plotted
Explanation of Solution
Formula Used: A frequency distribution is a table that represents the frequency of each data value, i.e. how many times each data value is repeated in data set.
Calculation:
List of data is as follows:
In above list, unique data values are:
Here,
Frequency distribution for above list of data is as follows:
Data Value | Frequency |
A | 8 |
B | 4 |
C | 4 |
D | 3 |
E | 3 |
Conclusion: Hence, a frequency distribution is constructed
