Further it involves the computation of the deviation of all the scores of a distribution from the Arithmetic Mean, ignoring the sign. This is found to be difficult for the below average/slow learners. Hence an attempt is made herewith to make the computation of Mean Deviation, an easy task,...
The mean deviation of the data values can be easily calculated using the method given below:–1st Step: Find the mean or the average value for the given data values.–2nd Step: Thereafter, find the difference of the mean value from each of the data values given, ignoring the signs.–3rd...
Mean Deviation Th e mean deviation is foun d by using this formula:$$ M e a n d e v i a t i o n = \frac { \sum | X - \overlin e { X } | } { n } $$$ w h e r e X = y a l u e $$$ \overlin e { X } = m e a n $$n = number of values||=absolu...

Learn about what mean absolute deviation is. Explore the mean absolute deviation formula and how to find mean absolute deviation, and see examples...
The standard deviation formula that you will use to find the standard deviation (SD) is shown below.x represents a set of numbers. For example, x could be {5, 6, 14, 1, 6, 10}. The mean is the average of the set of numbers....
Standard deviation and standard error are closely related. In fact, standard error of the mean depends on the standard deviation of the mean of the sampling distribution. To calculate the standard deviation from the standard error, multiply the standard error by the square root of the population ...
The empirical rule is applied to anticipate probable outcomes in a normal distribution. For instance, a statistician could use it to estimate the percentage of cases that fall in each standard deviation. Consider that the standard deviation is 3.1 and the mean equals 10. In this case, the firs...
Modern portfolio theory and related models use mean-variance optimization to come up with the best portfolio allocation on a risk-adjusted basis. Risk is measured as the portfolio's standard deviation, and the mean is the expected value (expected return) of the portfolio. This does utilize the...
Tracking error: We need to calculate the standard deviation of the "Excess Return" column. We used the STDEV function under the last cell in this column and got our answer: 9.36% Information ratio: We now divide the average annual excess return by the tracking error: ...
