Math Problem Statement

Make a frequency distribution table with 6 class intervals.

Solution

Let's begin by creating a frequency distribution table based on the data from the image you uploaded. First, I'll extract the data values, determine the range, and then compute the class intervals.

Step-by-Step Process:

  1. Extract Data: First, I will manually read the numbers from the image.

    • First row: 88.4, 89, 90.4, 51, 75.3, 75, 53.2, 79.3
    • Second row: 84, 85, 84.3, 85.8, 89, 77, 78.1, 78
    • Third row: 79.8, 64, 67, 72, 54.7, 58.5, 62, 64
    • Fourth row: 80.6, 52, 91.5, 68, 73, 55.4, 60.3, 63.9
    • Fifth row: 81, 82.9, 53, 86.5, 69.4, 74, 56, 61
    • Sixth row: 87.5, 55, 83.8, 85, 95, 70.8, 75, 57
    • Seventh row: 86.5, 92, 91.7, 84, 93, 94, 71.7, 76.5
  2. Determine the Range:

    • The smallest value is 51 and the largest value is 95.
    • Range = 95 - 51 = 44.
  3. Determine Class Intervals:

    • We need 6 class intervals.
    • Interval Width = 4467.33\frac{44}{6} \approx 7.33, so we can round it to 8.
  4. Construct the Class Intervals:

    • First interval: 51 - 59
    • Second interval: 60 - 67
    • Third interval: 68 - 75
    • Fourth interval: 76 - 83
    • Fifth interval: 84 - 91
    • Sixth interval: 92 - 99
  5. Frequency Distribution: Now, I will calculate the frequency for each interval based on the extracted data.

Let me calculate and organize the frequency distribution.Here is the frequency distribution based on the provided data and 6 class intervals:

Class IntervalFrequency
51 - 5910
60 - 677
68 - 759
76 - 839
84 - 9113
92 - 994

The interval with the highest frequency is 84 - 91, with a count of 13.

Would you like further details on how these intervals are constructed, or do you have any other questions?

Here are some follow-up questions:

  1. Would you like to see a cumulative frequency distribution?
  2. Do you want a histogram plotted for this data?
  3. Would you like to calculate the relative frequencies?
  4. Should I calculate the mean or median for this dataset?
  5. Would you like an explanation on how to find the mode from grouped data?

Tip: Class intervals should always be of equal width to ensure consistency in your frequency distribution table.
