The population mean is a measure of the central tendency of a population of data values. It is a single number which is calculated by finding the sum of all the data values in a population and then dividing that sum by the number of items in the population. For example, the population mean of the weight of 50 people is 50 kg, because the sum of their weights (500 kg) divided by the number of people (50) is equal to the average weight of the population (50 kg).

What is population mean in statistics?
The population mean is a summary statistic that tells you something about the population as a whole. If you take a sample from the population, the mean is the number you expect to see if you were to take another sample the same size. The population mean is usually calculated using the sum of all the numbers in the sample and dividing by the number of observations. So, if you have 10 data points, the mean is the sum of the 10 numbers divided by 10.
