Answer :
Let's analyze the data for both players and determine which measure of variability—interquartile range (IQR) or range—is most suitable for indicating consistency among the players.
### Interquartile Range (IQR)
The interquartile range (IQR) measures the middle 50% of the data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).
- For Player A, the IQR is 2.0.
- For Player B, the IQR is 1.0.
### Range
The range measures the difference between the maximum and minimum values in the dataset. It is calculated as:
[tex]\[ \text{Range} = \text{Maximum value} - \text{Minimum value} \][/tex]
- For Player A, the range is 7.
- For Player B, the range is 5.
### Consistency Determination
Consistency is typically better described by the IQR because it focuses on the spread of the middle half of the data and is less affected by outliers.
- Player A has an IQR of 2.0.
- Player B has an IQR of 1.0.
A smaller IQR indicates that the data points are closer to the median, meaning less variability and therefore more consistency.
### Conclusion
Player B is the most consistent, with an IQR of 1.0.
Thus, the correct choice among the given options is:
- Player B is the most consistent, with an IQR of 1.0.
(Note: There seems to be a typographical error in the provided options. The correct analysis shows Player B has an IQR of 1.0, not 1.5. The correct choice should be corrected as follows: "Player [tex]\(B\)[/tex] is the most consistent, with an IQR of 1.0.")
