This is due to the fact that the mean has valuable mathematical properties that make it convenient for use with inferential statistical analysis.
For example:
the sum of the ** deviations** of the numbers in a set of data from the mean is zero; and
the sum of the squared

Therefore, the *standard*** deviation** of portfolio P is
σ (RP ) = ασ (RA ) − (1 − α)σ (RB ).
As assets A and B are perfectly negatively correlated, we can construct portfolio P
such that its

Descriptive statistics are used because in most cases, it isn't possible to present all of your data in any form that your reader will be able to quickly interpret. The mean, the mode, the median, the range, and the *standard*** deviation** are all examples of descriptive statistics. The mean, median, and the mode are all measures of central tendency. They attempt to describe what the typical data point might look like. In essence they are all different forms of 'the average.'...

In Sharpe index, three things must be known:
the portfolio return,
the risk free rate of return - use the average return
(over the given period of time).

The ratio describes how much excess return you are

using the ** standard** curve formula. The curve was prepared by plotting various known betacyanin concentrations with their respective absorbance. The concentrations were calculated using the formula x=y/0.0084. Where x is the independent variable representing betacyanin concentration (µM) and y is the dependent variable representing betacyanin absorbance (460nm). Data was collected from the same studies done by other people and the mean and
