represents the data? 1,3,7,6,12,6,5,2,0,8,4,8,10,1
Beaver Frequency
0-4

Answer 1

Beaver Frequency

0-4 6

5-8 6

9-12 2

Explanation:

The maximum number of beaver observed are 12. In the table there are 3 subdivision, then the number of beaver are divided into 3 almost equal groups: 0-4, 5-8 and 9-12.

To find the frequency of each group, you have to count in the data how many times a number between the group appears, as follows:

0 - 4 beavers: 1,3,7,6,12,6,5,2,0,8,4,8,10,1 (6 times)

5 - 8 beavers: 1,3,7,6,12,6,5,2,0,8,4,8,10,1 (6 times)

9 - 12 beavers: 1,3,7,6,12,6,5,2,0,8,4,8,10,1 (2 times)
