WebWhen describing relationships between variables, a correlation nearer to 1.00 (plus or minus) indicates the relationship between variables is strong A factorial design involves more than one independent variable The simplest factorial design is the one that has two independent variables with two levels each WebMost correlation coefficients (assuming there really is a relationship between the two variables you are examining) tend to be somewhat lower than plus or minus 1.00 (meaning that they are not perfect relationships) but are somewhat above 0.00.
The values of both the sample and population Pearson correlation coefficients are on or between −1 and 1. Correlations equal to +1 or −1 correspond to data points lying exactly on a line (in the case of the sample correlation), or to a bivariate distribution entirely supported on a line (in the case of the population correlation). The Pearson correlation coefficient is symmetric: corr(X,Y) = corr(Y,X). WebMay 31, 2024 · The Pearson coefficient shows correlation, not causation.
