Answer:
The correct Answer is ( option A ).
Explanation:
The range is the easiest measure of variability to calculate. To find the range, follow these steps:
Order all values in your data set from low to high.
Subtract the lowest value from the highest value.
This process is the same regardless of whether your values are positive or negative, or whole numbers or fractions.
Range example:
Your data set is the ages of 8 participants.
Age
37
19
31
29
21
26
33
36
First, order the values from low to high to identify the lowest value (L) and the highest value (H).
Age
19
21
26
29
31
33
36
37
Then subtract the lowest from the highest value.
R = H – L
R = 37 – 19 = 18
The range of our data set is 18 years.
