Question
The value of r^2 is called: pearson product-moment correlation spearman's rho proportion of variance accounted for unreliability coefficient Scientists have obtained a correlation coefficient of 60 between depression and anxiety, which means that r^2 = 36. This means that: depression causes anxiety 36% of the time the combined unreliability of the depression and anxiety scores is .36 restriction of range has occurred 36% of the variation in depression and anxiety can be explained by the correlation between them A team of researchers has calculated a correlation coefficient of + 1.05, which indicates: a strong positive linear correlation a curvilinear correlation no correlation a calculation error If a psychologist interested in the relation between number of years working for a particular company and loneliness at work surveyed 40 workers at this company and figured a correlation between these two variables of-.90, the correlation is considered a weak positive linear correlation. weak negative linear correlation. strong positive linear correlation. strong negative linear correlation. The difference between a positive correlation and a negative correlation is that in a negative correlation, high scores go with high scores and low with low; in a positive correlation, high scores go with low scores and low with high. in a negative correlation, high scores go with low scores and low with high, in a positive correlation, high scores go with high scores and low with low. negative correlations are curvilinear, positive correlations are straight lines. negative correlations represent a weak relationship; positive correlations represent a strong relationship.Explanation / Answer
