Ms. Hernandez gave her students a biology test last week. Here are the test scores for each of the eleven students. Complete the grouped frequency distribution for the data. In the distribution, the frequency of a class is the number of test scores in that class. (Note that we are using a class width of 6.)

Grouped frequency distribution is a distribution of a data set of specific response that how often it is organized into the equal sized subsets of the possible response occur in the sample..The solution for the given table is.

66-71           3

72-77           5

78-83           2

84-89           1

Total number of the students is 11.

The test score result are 70,70,81,79,78,72,72,84,66,78,78.

Grouped frequency distribution

Grouped frequency distribution is a distribution of a data set of specific response that how often it is organized into the equal sized subsets of the possible response occur in the sample.

Arrange the test score in the ascending order as,

66,70,70,72,72,78,78,78,79,81,84.

Here,

The values in the 66-71 grouped frequency distribution is 3.

The values in the 72-77 grouped frequency distribution is 2.

The values in the 78-83 grouped frequency distribution is 5.

The values in the 84-89 grouped frequency distribution is 1.

Thus the solution for the given table is.

66-71           3

72-77           5

78-83           2

84-89           1
