Question

How can I Construct a frequency table to show this data ? and how can I use it in groups 0-4,5-9,10-14,15-19 and 20-24?

Answer 1

We have the following data: 21, 20, 0, 12, 1, 11, 0, 3, 1, 4, 9, 1, 9, 0, 13, 3, 7, 18, 8, 4, 7, 18, 0, 4, 1, 2, 0, 12, 12, 16.

We have to make a table with the following columns:

• element,: a number,

,

• frequency,: the number of times that the element appears in the list,

,

• cumulative frequency,: the sum of the frequencies until that element,

,

• relative frequency,: the quotient of the frequency and the total number of elements,

,

• cumulative relative frequency,: the sum of the relative frequencies until that element.

Answer

Ordering the elements and computing the elements above, we get the following table:
