In this chapter, we define the average and its types, i.e., mathematical averages which include the arithmetic mean, geometric mean, harmonic mean, median and mode. Also, we show when and where these averages are suitable to be used. Position measures, namely quartiles, deciles and percentiles also have been discussed. This chapter also gives techniques to measure the spread of the data around the average, these measures include range, quartile deviations, mean deviation, standard deviations and measures of asymmetry and peakedness of the data. The procedures for all these measures are outlined by SPSS.

Keywords: Arithmetic mean, Geometric mean, Harmonic mean, Standard deviation, Bowleys coefficient of skewness, Kurtosis.
