The numerical value for a correlation ___ a) can never be less than 1.00 b) can be greater than 1.00 c) and can be less than -1.00 and can never be less than - 100 d) can be great than 1.00 and can be lass than -1.00 The Pearson correlation measures _______ a) the degree of relationship without regard to the form of the relationship b) the degree to which the relationship is consistently one directional c) the degree of linear relationship d) the degree of A scatter plot shows a set of data points that are clustered close to a line that slopes down to the right Which of the following values would be closest to the correlation for these data? a) 0.80 b) 0.40 c) -0.40 d) -0.80 The results from a research study indicate that adolescents who watch more violent content on television also in more violent behavior than their peers The correlation between amount of TV violent tend to engage content and amount of violent behavior is an example of a) a positive correlation. b) a negative correlation. c) a correlation near zero. d) a correlation near A researcher reports that there is no consistent relationship between grade point average and the number of hours spent studying for college students. The correlation between grade point average and the number of hours studying example a) a positive correlation. b) a negative correlation. c) a correlation near zero. d) a correlation near one. A Pearson correlation of r = 1.00 between X and Y indicates ____. a) each time X increases, there is a perfectly predictable increase in Y b) every change in X causes a change in Y c) every increase in X causes an increase in Y d) All of the other 3 choices occur with a of + 1.00. A set of n = 5 pairs of X and Y values has sigma X = 10, sigma Y = 20, and sigma XY = 60. For this set of scores, the value of a) -20 b) -28 c) 20 d) 60Explanation / Answer
7) c) Can never be greater than 1 and less than -1.
8) c) The degree of linear relationship.
9) d) -0.80 because the two factors have strong negative correlation.
10) a) A positive correlation.
