Let's analyze the provided data sets for both Person A and Person B.
Person A: 40, 44, 37, 42, 43
Person B: 50, 41, 35, 38, 37
- Calculating the median:
- For Person A, when arranged in order: 37, 40, 42, 43, 44. The median (middle value) is 42.
- For Person B, when arranged in order: 35, 37, 38, 41, 50. The median is 38.
Verdict: Based on the median, Person A (42) has a faster typing speed than Person B (38).
- Calculating the mean:
- For Person A: (40 + 44 + 37 + 42 + 43) / 5 = 42.2
- For Person B: (50 + 41 + 35 + 38 + 37) / 5 = 40.2
Verdict: Based on the mean, Person A (42.2) has a faster typing speed than Person B (40.2).
- Calculating the mode:
- Both datasets have no repeating numbers, so there is no mode for both Person A and Person B.
Verdict: The mode is not a useful measure of center to describe the data sets.
- Calculating the range:
- For Person A: 44 - 37 = 7
- For Person B: 50 - 35 = 15
Verdict: Person B had a greater range of data (15) than Person A (7).
Based on this analysis, the true description about the data set is:
- The mode is not a useful measure of center to describe the data sets.
Thus, that is the correct response to choose.
