Document Summary
E. g. , if one thing increases, does the other increase, decrease, or stay the same? positive - as iv increases, dv also increases negative as iv increases, dv decreases. These are the two you have to figure out ^ Independence independence of cases there"s more but these are the ones you need to check for. Measures the extent that the spread of two variables matches. If people are above mean in one variable and above in another, they have a positive relationship. Ranges from +1 to -1; zero means there is no relationship perfect positive relationship: r = 1 no relationship: r = 0 perfect negative relationship: r = (-1) r -> t score -> p value. If most people"s scores are close to the line that best describes the relationship between the two variables, then the correlation will be large. Despite the different slopes, the correlations are all +1. 0 because there is no deviation from the line.
