The mean is appropriate for data that are normally distributed, because in this type of distribution the mean, median and mode are equal. It is also appropriate for data on an interval or ratio scale, because these scales have an inherent numerical order and zero point. Therefore, the mean provides a measure of central tendency that reflects the underlying numerical values of the data.
