Question

Question Help * The standard deviation, the range, and the interquartile range (QR) summarize the variability of the data. a. Why b. Why is the IQR sometimes preferred to the standard deviation? c. What is an advantage of the standard deviation over the IQR? is the standard deviation usually preferred over the ranges? a. Why is the standard deviation usually preferred over the range? A. The range is an average, while the standard deviation is the actual value. O B. The range only uses the largest and smallest observations, while the standard deviation uses all the data except the outliers O C. The standard deviation is sometimes negative, while the range never is. 0 D. The range is more affected by an outlier, and the standard deviation uses all the data b. Why is the IQR sometimes preferred to the standard deviation? A. The IQR only includes the largest and smallest observations, so it is easier to calculate O B. The IQR is not affected by an outler, while the standard deviation is affected by an outlier O C. The IQR uses all the data except the outliers, while the standard deviation uses all the data D. The IQR only uses a quarter of the data, while the standard deviation uses all the data c. What is an advantage of the standard deviation over the IQR? 0 A. The IQR is more difficult to determine, while the standard deviation can be found easily. O B. The standard deviation uses all the data, while the IQR uses all the data except outliers. ° C. The standard deviation takes into account the values of all observations, while the IQR only uses some of the data D. The IQR is an average, while the standard deviation is the actual value Click to select your answer lati

Explanation / Answer

(a) Option D- The range is more affected by an oulier, while the standard deviation uses all the data.

(b) Option B- The IQR is not affected by outliers, while the standard deviation is affected by an outlier.

(c) Option C - The standard deviation takes into account the values of all observations , while the IQR only uses some of the data.
