In this video, we simulate working out the averages of the salary structure of a company. We start by looking at how to find the mean and the limitations of using the mean. We then looked at mode, median and range. Finally, we finish by looking at finding the upper and lower quartiles and discuss how these can be used to calculate different averages. Check it out and let me know what you think.
