   Symbols for the mean: (an upper case X with a line above it) or (lower case x with a line above it) denote "the mean of the X scores". Thus if the X scores are 2, 3 and 4, then X = (2+3+4)/3 = 3.0. If you have two sets of scores, one lot would be the X scores and the others would be the Y scores.

   The x bar (x̄) symbol is used in statistics to represent the sample mean, or average, of a set of values. It's calculated by adding up all the numbers in the sample and then dividing by the number of values in that sample.

   Dec 29, 2023 · In summary, the key differences between the two mean formulas are µ vs. x̅ (mu vs. x bar symbols) and N vs. n. In each case, the former relates to the population, while the latter is for the sample mean formula. Summing up values and dividing by the number of items is consistent in both formulas.

   What does m mean in statistics?

   • 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. In journal articles, the mean is usually represented by M, and the median by Mdn. Standard deviation symbols:

   What does s mean in statistics?

   • s (the greek lower-case letter,"sigma") is usually used for the population standard deviation. s is used to denote the standard deviation of a sample of scores. The formula for the standard deviation differs slightly, depending on whether it is the population s.d., the sample s.d., or the sample mean used as an estimate of the population s.d..

   The Sampling Distribution of the Sample Mean. 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) then the mean of all sample means (x-bars) is population mean μ (mu).
