How to find the sample mean from the population mean?

Definition of Sample Mean. The sample mean is the mean calculated from a group of random variables, drawn from the population. It is regarded as an efficient and unbiased estimator of population mean which means that the most expected value for the sample statistic is the population statistic, irrespective of the sampling error.

What does the symbol σ stand for in statistics?

The symbol ‘σ’ represents the population standard deviation. The term ‘sqrt’ used in this statistical formula denotes square root. The term ‘Σ (X i – μ) 2 ’ used in the statistical formula represents the sum of the squared deviations of the scores from their population mean.

Which is the formula for population standard deviation?

The population standard deviation is a measure of the spread (variability) of the scores on a given variable and is represented by: σ = sqrt [ Σ (X i – μ) 2 / N ] The symbol ‘σ’ represents the population standard deviation. The term ‘sqrt’ used in this statistical formula denotes square root.
