The mean is an example of a measure of central tendency of the data. Such measures are used to find a ``typical'' value for the data. Other measures of central tendency are the harmonic mean, the geometric mean, the quadratic mean, the median, and the mode. • A major advantage ...
In this tutorial, you’ll learn how to identify and calculate these measures of central tendency:Mean Weighted mean Geometric mean Harmonic mean Median ModeMeanThe sample mean, also called the sample arithmetic mean or simply the average, is the arithmetic average of all the items in a dataset...

Define and interpret skew, explain the meaning of a positively or negatively skewed return distribution, and describe the relative locations of the mean, median, and mode for a non-symmetrical distribution. Briefly define or explain each of these terms....
