If points are two spread out, so that low scores on one variable are related to both high and low scores on the other variable there is zero association: relationships, linear, curvilinear, none. Ice cream sales and shark attacks positive. Outliers: extreme values that have a disproportionate effect on the correlation, especially when the sample size is small. Is <0. 30 too low: maybe, but we need to consider all of the factors that might account for that variance, correlates of life satisfaction, (cid:862)r(cid:863) =0-0. 15.
