Question 1: In the stem and leaf diagram below, the data values are represented. Identify the maximum and minimum values and calculate the Range.

Answer: Maximum: 87, Minimum: 23, Range: 64

Question 2: Given the data set: 45, 52, 47, 50, 55, 49, 48, 53, 46. Find the Range.

Answer: Range = 55 - 45 = 10

Question 3: The stem and leaf diagram shows the following data: 12, 15, 17, 14, 19, 13, 16. Calculate the Range.

Answer: Maximum: 19, Minimum: 12, Range: 7

Question 4: A dataset has values: 102, 98, 105, 110, 99. What is the Range?

Answer: Range = 110 - 98 = 12

Question 5: The data from a survey are: 38, 42, 37, 41, 39, 40. Find the Range.

Answer: Maximum: 42, Minimum: 37, Range: 5

Question 6: Construct a stem and leaf diagram with the following data: 23, 25, 27, 24, 26. Then determine the Range.

Answer: Range = 27 - 23 = 4

Question 7: A class's test scores are: 70, 75, 68, 80, 72, 78. Find the Range.

Answer: Maximum: 80, Minimum: 68, Range: 12

Question 8: Given a stem and leaf diagram with data: 34, 36, 33, 35, 37. Identify the maximum and minimum values and compute the Range.

Answer: Maximum: 37, Minimum: 33, Range: 4

Question 9: A set of measurements: 150, 145, 160, 155, 148. Calculate the Range.

Answer: Range = 160 - 145 = 15

Question 10: Analyze the following data from a survey: 22, 25, 20, 23, 21. Find the Range and explain what it tells us about the data spread.

Answer: Range = 25 - 20 = 5; It indicates the spread between the smallest and largest data points.

Question 11: Identify and correct the common mistake in calculating Range: If a dataset has values 10, 12, 14, 16, students subtract the smallest from the largest and get 4.

Answer: Correct calculation: 16 - 10 = 6. The mistake was in the subtraction result; it should be 6, not 4.
