FACTS AND CAUTIONS ABOUT CORRELATION AND REGRESSION. If you switch x and y the correlation stays the same. You can tell by looking at the formula for r. r does not change if we change the units of measurement on x and/or y. This is because r uses standardized values. Standardized means how many standard deviations from the mean.

The correlation seems strong – but if we calculate it we’ll find that r = 0. ε residual error, true value, predicted value. ε. The least squares principle: So what we’re looking for is the parameters (a, b) of the regression line. So all we really need to know is . N and r !! y = ax + b

where r is the Pearson correlation coefficient (which we calculated in the preceding lecture). Once we know b, we can find a: where and are the means of x and y, respectively. Prediction. We now have our linear regression equation. One thing we can do with it is to predict the y value for some new value of x.

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.

The Correlation Statistic ( r ) provides two separate pieces of information. (1) the sign, negative or positive tells us the direction of the relationship. If a correlation is positive it indicates that higher levels or one variable predict higher levels of the second variable (and conversely that lower levels of …

Pearson Product Moment Correlation Coefficient , aka, Pearson r. A numeric measure of strength and direction of linear relationship between paired score values. r is a standardized quantity. A standardized measure whose value is always between -1 and +1 inclusive. So it doesn’t matter what size numbers you’re correlating.
