The correct interpretation from the interquartile ranges of Stock A and Stock B is:
- Stock B has more variability than Stock A.
The interquartile range (IQR) measures the spread of the middle 50% of a data set. A larger IQR indicates that the data points are more spread out, implying greater variability. Since Stock B has an IQR of 11 and Stock A has an IQR of 3, this shows that Stock B displays more variability in its stock prices compared to Stock A.
The other statements are not accurate interpretations based on the interquartile range:
- The stock price for Stock B being higher than Stock A cannot be inferred from the IQR alone.
- Stock A does not have more variability; in fact, it has less.
- The statement about the price difference does not relate to the IQR.
