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.

Let's create a grouped frequency table with intervals of 0–10, 10–20, etc., for the provided dataA 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.

Let's create a grouped frequency table with intervals of 0–10, 10–20, etc., for the provided

Data:

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).
