Find the Percentage Frequency -4 , -2
,
Step 1
Since the number of items in the data is too small to be arranged in a set of classes, it is easier to list the items with their related frequencies.
Step 2
The relative frequency of a data class is the percentage of data elements in that class. The relative frequency can be calculated using the formula , where is the absolute frequency and is the sum of all frequencies.
Step 3
is the sum of all frequencies. In this case, .
Step 4
The relative frequency can be calculated using the formula .
Step 5
Simplify the relative frequency column.
Step 6
Multiply every relative frequency by to get the percentage frequency.
Step 7
Simplify the Percentage column.
