The salaries received in 2018 by the some of the highest paid executives of 14 international companies (in $000s) are as follows:
2411, 1889, 1520, 1260, 980, 956, 947, 924, 899, 870, 856, 655, 700, 720
a.
Range = 2411 - 655 = 1756
b.
range is about how much your data covers, standard deviation has to do more with how much difference there is between the scores. If all of the scores are grouped around the average, then your standard deviation will be lower.
Standard deviation is mostly preferred.
c.
if a distribution is skewed, then the mean is usually not in the middle. Notice that in this example, the mean is greater than the median. This is common for a distribution that is skewed to the right.
