Which data set has the least sample standard deviation Data

Which data set has the least sample standard deviation? Data set (ii), because it has more entries that are close to the mean. Data set (i), because it has more entries that are farther away from the mean Data set (iii), because it has less entries that are farther away from the mean How are the data sets the same? How do they differ? The three data sets have the same mean and mode but have different medians and standard deviation The three data sets have the same mean median and mode but have different standard deviations. The three data sets have the same mode but have different standard deviations and means. The three data sets have the same standard deviations but have different means.

Solution

d) the data set have same SD but have different mean
