WebQuestion 6 (5 points) A value of Pearson's correlation coefficient of r = 0.92 indicates that as the independent variable x increases the dependent variable Y remains constant: Pearson's correlation does not measure the correlation between x and y and thus no conclusion can be made about the dependent variable Y: the dependent variable Y decreases. the …

WebOn the other hand, East is not statistically significant because its p-value (0.092) is greater than the usual significance level of 0.05. ... The calculation for R is (unsurprisingly) just taking the positive square root of R-squared. R represents the correlation between a set of variables with another variable. In the regression context, ... WebJun 25, 2024 · This metric, 1 − M S E / v a r ( y), is the coefficient of determination, R 2. So lets get a sense of the range of R 2. It’s pretty clear that a model that always predicts the mean of y will have an MSE equal to v a r ( y) and an R 2 of 0. A model that is worse than the mean-prediction model (such as a model that always predicts a number ... mario fitsch

Generally yes, a correlation of 0.25 is considered substantial (not necessarily high) depending on what you are looking at. I've also seen 0.3 as a cut-off point but we learned that a corr of 0.2 or higher already hints at a low positive correlation. [deleted] • 5 yr. ago.
