Source sentences:
text: If repeated random samples of a given size n are taken from a population of values for a quantitative variable, where the population mean is μ (mu) and the population standard deviation is σ (sigma)
text: If the data values in a normal distribution are converted to z-scores in a standard normal distribution the empirical rule describes the percentage of the data that fall within specific numbers of standard deviations (σ) from the mean (μ) for bell-shaped curves.
text: theoretical standard deviation (sigma) of the population model.
text: In other words, the standard deviation σ (sigma) is the square root of the variance of X; i.e., it is the square root of the average value of (X − μ)2.
text: The population variance is σ2 (sigma squared) and population standard deviation is σ (sigma).
text: The population standard deviation is σ (sigma) and sample standard deviation is s.
