18) What is the difference between the standard deviation of a single variable and (1 PS) the standard error? Verdana v 10m v B I Q A v I v 1; iEvEva'b E (269 OS 1. Standard deviation indicates the spread of a group of values from their mean, whereas standard error measures the precision of an estimate, in other words the exactness of the estimate. 2. Standard deviation is equal to the square root of the variance, whereas standard error is equal to the standard deviation divided by the square root of the sample size. 3. Standard deviation provides more specic values as sample size increases, whereas standard error decreases as sample size increases. 4. Standard deviation belongs to descriptive statistics, whereas standard error belongs to inferential statistics. 94 WORDS POWERED BY TINY 4
