The term x bar refers to the sample mean or the average of a set of values It is denoted by placing a bar or a line over the variable x representing the mean value of x The formula to calculate the sample mean or x bar is x bar x1 x2 x3 xn n An unbiased x bar means that the estimate is equally likely to be too high or too low In other words it tends to be correct on average So our x 6 serves as an estimate of the population mean 6
In statistics x bar pronounced as x bar represents the sample mean It is a mathematical notation used to denote the average or central tendency of a sample To calculate x bar you need to follow these steps 1 Add up all the values in your sample 2 Count the number of values in your sample 3 Divide the sum of the values by the count 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 mu and the population standard deviation is sigma then the mean of all
