Question

How do you group raw data into a group frequency distribution table using the Sturges rule of approximation?

a. Count the occurrences of each value
b. Determine the range of the data
c. Divide the range by the number of desired classes
d. All of the above

Answer 1

To create a group frequency distribution table using Sturges' rule, you would count the data occurrences, determine the data range, and divide by the number of desired classes.

Step-by-step explanation:

To group raw data into a group frequency distribution table using the Sturges rule, you would follow several steps. First, count the occurrences of each value to identify how often each data point shows up. Second, determine the range (which is the difference between the largest and the smallest data values). Lastly, divide this range by the number of desired classes (which can be determined by Sturges' rule of thumb: 1 + 3.3 log(n) where n is the number of data points). Therefore, the correct answer is d. All of the above.
