Question

ten cyclists were each asked the distance in miles they biked last week. their responses are given below. complete the grouped frequency distribution for the data. in the distribution, the frequency of a class is the number of distances in that class. (note that we are using a class width of 5.)
distance in miles
7 6 5 16 6
4 10 4 12 17
distance in miles frequency
1 to 5
6 to 10
11 to 15
16 to 20

Explanation:

Step1: Count 1 to 5

Check each data point: 5, 4, 4. So count is 3.

Step2: Count 6 to 10

Data points: 7, 6, 6, 10. Count is 4.

Step3: Count 11 to 15

Data point: 12. Count is 1.

Step4: Count 16 to 20

Data points: 16, 17. Count is 2.

Answer:

Distance in miles	Frequency
6 to 10	4
11 to 15	1
16 to 20	2
