Identify the symbols used for each of the following: (a) sample standard deviation; (b) population standard deviation; (c) sample variance; (d) population variance. a. the symbol for sample standard deviation is ▼ . b. the symbol for population standard deviation is ▼ s s squared sigma sigma squared . c. the symbol for sample variance is ▼ s s squared sigma sigma squared . d. the symbol for population variance is ▼ s s squared sigma sigma squared .

The symbol for standard deviation is s

The symbol for population and the standard deviation is Sigma  

The symbol for sample population is sigma sigma squared

The symbol for population variance is sigma squared.  

Explanation:

Sigma square is the sum of X minus the mean squared divided by n.

 Sigma is a standard deviation, is the measured amount of variation or dispersion of a set of values. The standard deviation is the random variables, statistics variables, data set and the probability distribution is the square root of its distribution.
