Subject 4. Measures of Center Tendency
represent all the observations in the data set. Population Mean The population mean is the average for a finite population. It is unique; a given population has only one mean. <span>where: N = the number of observations in the entire population X i = the ith observation ΣX i = add up X i , where i is from 0 to N Sample Mean The sample mean is the average for a sample. It is a statistic and is used to estimate the population mean.
