Please explain Measures of Association, Measures of Correlation, and Measures of Dispersion.
Homework Answers
The measures of association refer to a wide variety of coefficients (including bivariate correlation and regression coefficients) that measure the strength and direction of the relationship between variables; these measures of strength, or association, can be described in several ways, depending on the analysis.Correlation between sets of data is a measure of how well they are related. The most common measure of correlation in stats is the Pearson Correlation.In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed.

Are any of the measures of dispersion among the range, the variance, and the standard deviation, resistant? Explain. Choose the correct answer below. O A. Yes, the variance is resistant because it has squared units, so is always positive. OB. No, all of these measures of dispersion are affected by extreme values. OC. Yes, the standard deviation is resistant because it is calculated using the mean, which is resistant. OD. Yes, the range is resistant because it always includes all...
