Question

Identify the symbols used for each of the following:

(a) sample standard deviation
(b) population standard deviation
(c) sample variance
(d) population variance

Answer 1

The symbols used for each of the following are: a) sample standard deviation: s b) population standard deviation: σ c) sample variance: s2, and d) population variance: σ2

Step-by-step explanation:

These symbols are commonly used in statistics to represent the standard deviation and variance of a sample or population. The sample standard deviation, sample variance, population standard deviation, and population variance are important measures of variability in data.

The sample standard deviation and sample variance are used when analyzing data from a sample, while the population standard deviation and population variance are used when analyzing data from a population. Therefore the symbols used for each of the following are: sample standard deviation(s), population standard deviation(σ), sample variance(s2), and population variance(σ2).
