The correlation coefficient of this scatterplot is -0.8Use the drop down menus below to describe the relationship between the two variables. The relationship between the two variables is

Choose the most likely correlation value for this scatterplot:r = 0.436r = 0.100r = −0.897r = 0.995r = −0.575

If there is no relationship (linear or otherwise) between two quantitative variables as observed on a scatterplot, the value of the correlation coefficient, r, is likely to be which of the following? Closer to 1 Closer to −1 Closer to 0 Either closer to −1 or 1

The following data represents the scores of two variables, x and y: x: 10, 15, 20, 25, 30 y: 20, 25, 30, 35, 40 The correlation coefficient between x and y is:a.0.7b.0.8c.0.9d.1

The coefficient of correlation r between two bivariate data is –0.80.  Which best describes the correlation?*There is no correlation because the computed r is negative.The correlation is very high but negative.The correlation is very low but negative.The strength of the correlation is negligible.None of the above

If the plotted points in a scatter diagram lie from upper left to lower right, then the correlation is(a) Positive(b) Zero(c) Negative(d) none of these
