      If your correlation coefficient is a larger negative number than the critical region, your data indicate a significant negative correlation. The closer your r-value is to —1.0, the stronger the negative correlation. REPORTING YOUR RESULTS. The examples below show how the results of your analysis of linear correlation should be presented ...

      Use the regression line to predict the value of a pick up track that is 3 years old. For the next two problems construct a scatterplot, find the value of the linear correlation coefficient r, find the critical value of r from Table A – 5 by using a = 0.05, and determine whether there is a linear correlation between the two variables. #14 p.503.

      The Pearson r “correlation coefficient” is a summary statistic that indicates both the strength and direction of the relationship between two variables. It has a value of between ‐1 and +1 – Values less than zero (e.g ‐0.8) indicate a negative correlation. Values greater than zero (e.g. +0.8) indicate a positive correlation

      Any value of r greater than a positive critical value or less than a negative critical value will be significant, and the null hypothesis will be rejected. Example: Using Table I, test the significance of the correlation coefficient r = 0.0667, at , and sample size is 9. Section 10.3 Regression
