To find the quartiles, use the same procedure as for the median, but take the quarter- and three-quarter-point instead of the mid-point. CAPM formula shows the return of a security is equal to the risk-free return plus a risk pre… There are three measures of average: mean, median and mode. This is done in many ways such as: regression formulas, means, r-squared calculations, and ratio analysis. However, it can be skewed by ‘outliers’, values which are atypically large or small. The distribution of data is important to … It is useful on those systems for which there are very clear definitions.
