Consider the bivariate data set of two variables X and Y of metric scale:

 xi 7 24 35 51

 yi 187 256 295 359 

(a) Compute and compare the coefficients of variations respectively for X and Y .

 (b) Are there outliers of the measures of the variable Y in the data set? (Reason computationally) 

(c) Compute and interpret the corresponding correlation coefficient.

Answer rating: 100% (QA)

To compute the coefficients of variation for variables X and Y we need to calculate the standard deviation and mean for each variable Given data xi 7 ... View the full answer
