Registers the frequencies of the classes of the grouped data.
k
-th term of the array corresponds to the frequency of the k
-th class.The frequencies are passed as a array parameter where the first term of the array corresponds to the frequency of the first class.
If we grouped the data consisting of the heights of a collection of
people in accordance with the intervals: 0
m - 1.20
m,
1.21
m - 1.50
m, 1.51
m - 2.00
m,
2.01
m - 3
m. Where the corresponding number of people
in each of these interval's is:
0
m - 1.20
m is: 5
1.21
m - 1.50
m is: 25
1.51
m - 2.00
m is: 30
2.01
m - 3.00
m is: 3
Therefore, the array which describes the frequencies of the classes is:
{5, 25, 30, 3}
.
