if the standard deviation of the two samples were to be vast

if the standard deviation of the two samples were to be vastly different, what would you conclude about the two groups?

Thanks!

Solution

if the standard deviation of the two samples were to be vastly different, the data set with the larger standard deviation has more variability compared to its mean. In other words, the data points in the data set with the larger standard deviation are more spread out than the data points in the data set with the smaller standard deviation.
