Multivariate analysis is appropriate to examine complex human behavior and demographic characteristics .However, multiple covariates with high correlation may complicate interpretation of a regression analysis .For example, having a highly correlated variable in a model can result in significant coefficient changes of other variables. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger. If the relationship between taking a certain drug and the reduction in heart attacks is r = 0.3, this might be considered a weak positive relationship in other fields, but in medicine its significant enough that it would be worth taking the drug to reduce the chances of having a heart attack. 0.50. c. 0.75. d. 0.90. The slope of the line is negative (small values of X correspond to large values of Y; large values of X correspond to small values of Y), so there is a negative co-relation (that is, a negative correlation) between X and Y.

The correlation can be used to measure the quadratic relationship. In the present work, Mo/VC multilayers with constant period (10 nm) and different modulation ratios (from 6:4 to 9:1) were deposited by dc magnetron sputtering. This means that when one variable increases by one, the other variable also increases by the same amount. c. The range of values for a correlation is from 0 to 1. d. All of.
