4- Variance and Standard deviation (how far the data values lie from the mean) The mean, mode, and median do a nice job in telling where the center of the data set is, but often we are interested in more. For example, a pharmaceutical engineer develops a new drug that regulates iron in the blood. Suppose she finds out that the average sugar content after taking the medication is the optimal level. This does not mean that the drug is...
Select allof the true statements ahout the standard deviation of a quantitative variable. on represents how far a group of values are from the mean of those values, on average. Standard deviation is never negative. If a set of values has a mean of 0 and a standard deviation of will have no effect on the standard deviation. The standard deviation of a set of values is equal to 0 if and only if all of the values are the...
