Question

6. Twenty students were asked how many hours they worked per day. Their responses are as follows:22776332552564255775Construct a frequency table (including a relative frequency column) to describe this data.ValueFrequencyRelative Frequency234567

Answer 1

Explanation

The frequency of a value in a table is the number of times it appears. For example, the number 2 occurs, in the table, 5 times:

22776

33255

25642

55775

On the other hand, the relative frequency of a value is calculated by dividing its frequency by the total number of data. For instance, the relative frequency of 2 is

$RF(2)=\frac{5}{20}=0.25.$Answer

Using the definitions above, we get
