Bivariate and Univariate Data

The correlation coefficient of -0.95 implies

• strong positive association

• weak negative association

• weak non-linear association

• strong negative association

Estimate the correlation coefficient of

the scatter plot shown above

• 0.75

• -0.99

• 0.13

• -0.88

Pearson's correlation coefficient is used to

• find the standard deviation of the response variable

• find how strongly two variables are associated

• how good looking the scatterplot is

• the gradient of the regression line

These are grades for student X in a certain course Grades (%) : 75, 59, 68, 82, 95, 51, 88, 62, 76 This is an example of_______
