Correlation and Regression. ... Graphically, we can construct a scatterplot. Numerically, we can calculate a correlation coefficient and a regression equation. Correlation. The Pearson correlation coefficient, r, measures the . strength. and the . direction. ... The slope in the equation equals the amount that changes when x increases by one unit.

The coefficient of determination is a number between 0 and 1, inclusive. That is, If r2 = 0, the least squares regression line has no explanatory value. If r2 = 1, the least-squares regression line explains 100% of the variation in the response variable.

So the correlation coefficient is sqrt(.891) = +/- .944. (Make sure the sign of the coefficient matches the slope of the regression line. Since the slope is positive, the correlation is positive too: r=.944). 33. In the ANOVA table, the F-statistic is 57.4. This F value is the test statistic used in …

2-7 Linear Regression, Correlation, CausationDate_____ I can create and use a line of best fit both by hand (using two points) and using technology (linear or exponential). I can explain the meaning (using appropriate units) of the slope and y-intercept of a linear function in a real-world situation.

Correlation. The scatterplot gives us a general idea about whether there is a linear relationship between two variables. More precise: The coefficient of correlation (denoted r) is a numerical measure of the strength and direction of the linear relationship between two variables.
