1. Characterizes the spread of a group
Here group refers to the population, thus the spread of population is given by population standard deviation
D. Population standard deviation
2. Characterizes the average value of a group
Here group refers to the population, thus, the average value of population is given by population mean.
C. Population mean
3. Characterizes the average value of a subgroup
Here the subgroup refers to the sample. The average value of sample is given by sample mean.
A. Sample mean
4. Characterizes the distribution of a subgroup
The subgroup refers to sample. It is characterized by sample standard deviation.
E. Sample standard deviation
5. Characterizes percentages of a normal distribution
z-values are used to characterize the percentages in a normal distribution.
