Explanation:

Define the range of a data set

Using the Range Calculation knowledge point

$$ \text{Range} = \text{Maximum value} - \text{Minimum value} $$

Thus, the range is found by subtracting the minimum data entry from the maximum data entry. This matches option A.

Identify an advantage of the range

Using the Range Calculation knowledge point
The range is highly straightforward to calculate because it only requires finding the maximum and minimum values and subtracting them. This makes it very easy to compute. This matches option C.

Answer:

Question 1

• (A) The range is found by subtracting the minimum data entry from the maximum data entry. (Correct answer)
• (B) The range is found by subtracting the first data entry from the last data entry.
• (C) The range is found by adding the first and last data entries.
• (D) The range is found by adding the minimum and maximum data entries.

Question 2

• (A) It uses all entries from the data set.
• (B) It uses only two entries from the data set.
• (C) It is easy to compute. (Correct answer)
