Which of the following is the most appropriate finding

? You want to compare the association between two variables so you decided to:

1. Run a correlation test which returns a coefficient of 0.2 at a p value of 0.13. The range of the variables 1 is 10 and the range of variable 2 is 100. You reject any useful association between the variables

2. Check the relative ranges of the variable and then a covariance test

3. Run a correlation test which returns a coefficient of 0.45 with an accompanying p value of 0.07. You decide the correlation is large and significant

4. You run a correlation test and find a correlation at 0.93 with a significance of 0.01. This enables you to include both variables as independents in a multivariate regression
