Question

identify the symbols used for each of the following: (a) sample standard deviation; (b) population standard deviation; (c) sample variance; (d) population variance. if sample data consist of weights measured in grams, what units are used for these statistics and parameters? a. the symbol for sample standard deviation is b. the symbol for population standard deviation is c. the symbol for sample variance is d. the symbol for population variance is

Explanation:

Step1: Recall sample standard - deviation symbol

The symbol for sample standard deviation is $s$.

Step2: Recall population standard - deviation symbol

The symbol for population standard deviation is $\sigma$.

Step3: Recall sample variance symbol

The symbol for sample variance is $s^{2}$.

Step4: Recall population variance symbol

The symbol for population variance is $\sigma^{2}$.

Answer:

a. $s$
b. $\sigma$
c. $s^{2}$
d. $\sigma^{2}$
