The term variance refers to a statistical measurement of the spread between numbers in a data set.
Advantages and Disadvantages of Measures of Variability
Problems related to data sets as well as grouped data are discussed. In earlier classes, you have studied measures of central tendency such as mean, mode, median of ungrouped and grouped data. Find the mean and median. Elementary statistics formulas Statistics formulas such as mean median mode, variance, and standard deviation formulas are given here in accordance with the number of observations n Median, Standard Deviation The mean is found by adding all the values in the set, then dividing the sum by the number of values. This is found by taking the sum of the observations and dividing by their number. Mean and Standard Deviation The mean The median is not the only measure of central value for a distribution.

Moving average convergence divergence, or MACD, is one of the most popular tools or momentum indicators used in technical analysis. This was developed by Gerald Appel towards the end of s.

The term "arithmetic mean" is preferred in some contexts in mathematics and statistics, because it helps distinguish it from other means , such as the geometric mean and the harmonic mean. In addition to mathematics and statistics, the arithmetic mean is used frequently in many diverse fields such as economics , anthropology and history , and it is used in almost every academic field to some extent. For example, per capita income is the arithmetic average income of a nation's population. While the arithmetic mean is often used to report central tendencies , it is not a robust statistic , meaning that it is greatly influenced by outliers values that are very much larger or smaller than most of the values.
Mean deviation is a measure that removes several shortcomings of other measures i. Its merits and demerits can be discussed as below. As in case of X, every term is taken in account hence, it is certainly a better measure than other measures of dispersion i. Range, Percentile Range or Quartile Range. Mean deviation is extensively used in other fields such as Economics, Business, Commerce or any other field of such type,.
