WebbIn statistics, the mean is the most common method to measure the center of a data set. It’s a fundamental yet important part of the statistical analysis of data. If we calculate the average value of the population set, then it is called the population mean. WebbExamples of statistics are the mean, median, mode, standard deviation, range, and correlation coefficient, among others. Statistics, and procedures for computing statistics, were discussed in detail in an earlier chapters. If a different sample were taken, different scores would result.
