Final answer:
The symbols for the sample and population standard deviation, variance, mean, and proportion.
Step-by-step explanation:
The sample standard deviation is represented by the symbol s. It is used when calculating the standard deviation from a sample.
The population standard deviation is represented by the Greek letter σ. It is used when calculating the standard deviation from a population.
The sample variance is represented by the symbol s². It is the average of the squares of the deviations in a sample.
The population variance is represented by the symbol o². It is the average of the squares of the deviations in a population.
The population mean is represented by the symbol μ, and the sample mean is represented by the symbol yˉ.
The sample proportion is represented by the symbol s, and the population proportion is represented by the symbol ρ.
