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.  

the correct answer is "hematoma formation, with ligaments that are stretched, partially, of fully torn" ankle sprain are produced by an injury to the tough bands of tissue (ligaments) that surround and connect the bones of the leg to the foot. this causes several damage to the ankle including hematoma formation and ligament injury .
