In about statistics range is the length of the smallest musical interval which contains all the dat a. spue can be calculated by subtracting th! e sample minimum from the sample maximum. This will therefore render the statistical dispersion. The averages can also be defined as the mean. It is a issue that is obtained by adding several quantities to exacther and dividing by the number of quantities. out(a) of these three the most commonly used measurement of dispersion is standard deviation. [pic] In our study the crush measurement of dispersion is standard deviation and the best used technique...If you want to get a full essay, order it on our website:
