Math Problem Statement
What is a frequency distribution? Form a grouped frequency table of intervals 0-10, 10-20 etc. from the following data: 5, 23, 49, 50, 38, 37, 25, 30, 29, 42, 37, 18, 12, 13, 9, 18, 27, 12, 50, 47, 48, 29, 30, 32, 37, 27, 41, 19, 32, 27.
Solution
A frequency distribution is a summary of how often each value or range of values occurs in a dataset. It organizes data into categories or intervals, making it easier to observe the distribution and identify patterns or trends.

It organizes data into categories or intervals, making it easier to observe the distribution and identify patterns or trends.
Let's create a grouped frequency table with intervals of 0–10, 10–20, etc., for the provided
Data:
Frequency Table
Interval | Frequency |
---|---|
0–10 | 2 |
10–20 | 6 |
20–30 | 8 |
30–40 | 7 |
40–50 | 4 |
50–60 | 3 |
Explanation
- 0–10: There are 2 values (5, 9).
- 10–20: There are 6 values (18, 12, 13, 12, 18, 19).
- 20–30: There are 8 values (23, 25, 27, 27, 29, 29, 27, 27).
- 30–40: There are 7 values (30, 30, 32, 32, 37, 37, 37).
- 40–50: There are 4 values (42, 41, 47, 48).
- 50–60: There are 3 values (50, 50, 49).
