Suppose you wish to study the relationship between the number of 'likes' on Facebook and the number of 'friends' one has on Facebook. Describe the statistical technique you would use.  ?

What will be an ideal response?

?I would the linear regression technique to study the relationship between number of 'likes' one gets and the number of friends one has on Facebook. The number of friends will be the independent or predictor variable. The number of likes will be the dependent variable. We expect a positive association between the two variable and we can expect a positive slope in the the linear regression. I would like to see an r-squared value of 0.70 or higher to ensure that at least 70% of the variability in the dependent variable is described by the linear regression.?
