Question

Use a class limits and class boundaries calculator.

a) Construct a frequency distribution
b) Find the mean
c) Calculate standard deviation
d) Determine the mode

Answer 1

To construct a frequency distribution, find the mean, calculate standard deviation, and determine the mode, follow these steps.

Step-by-step explanation:

1. To construct a frequency distribution, organize the data into a chart with five intervals of equal width, labeling the columns as Enrollment and Frequency.
2. To find the mean, sum up all the enrollments and divide by the total number of entries.
3. To calculate the standard deviation, subtract the mean from each enrollment value, square the differences, sum them up, divide by the total number of entries, and take the square root of the result.
4. To determine the mode, identify the value or values with the highest frequency in the distribution.
