What is the symbol for sample mean?
X̄
(symbol: X̄, M) the arithmetic average (mean) of a set of scores from cases or observations in a subset drawn from a larger population.
What is the MU in stats?
The symbol ‘μ’ represents the population mean. The symbol ‘Σ Xi’ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on. The symbol ‘N’ represents the total number of individuals or cases in the population.
What does M stand for in stats?
population mean
m (the greek letter “mu”) is used to denote the population mean. The population mean is worked out in exactly the same way as the sample mean: add all of the scores together, and divide the result by the total number of scores.
What is the symbol for mean and standard deviation?
Thus, the sample mean (x̅) is an estimate of the population mean (µ), and the sample standard deviation (s) is an estimate of the population standard deviation (σ). Thus the symbol ‘σ’ is therefore reserved for ideal normal distributions comprising an infinite number of measurements.

What are the basic symbols in statistics?
μ = ( Σ X i ) / N. The symbol ‘μ’ represents the population mean. The symbol ‘Σ X i’ represents the sum of all scores present in the population (say, in this case) X 1 X 2 X 3 and so on. The symbol ‘N’ represents the total number of individuals or cases in the population.
What does the symbol X mean in statistics?
The x-bar symbol, x̄, is used in statistics to represent the mean of a set of data. This is the arithmetic mean, which is what most people think of when they say “average” – the sum of all the measurements divided by the total number of measurements.
