Statistical ratios | Statistical deviation and dispersion
In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and which is used to make comparisons within and between data sets. Since it is based on quantile information, it is less sensitive to outliers than measures such as the Coefficient of variation. As such, it is one of several Robust measures of scale. The statistic is easily computed using the first (Q1) and third (Q3) quartiles for each data set. The quartile coefficient of dispersion is: (Wikipedia).
Find the reference angle of a angle larger than 2pi
👉 Learn how to find the reference angle of a given angle. The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we determine the quadrant on which the given angle lies and use the reference angle formula for the quadrant

Measures of Variability, Variance, Standard Deviation, & Dispersion in Business Statistics (Week 5B)
We explore measures of variability such as range, interquartile range, variance, standard deviation, percentiles and quartiles. We explore how to create variance by squaring deviation scores then set it all right again with the standard deviation. Dr. Daniel shows you how to create measure
