-.147034 what type of correlation is this?
negative, weak
When are is close to -1 does it indicate a weak negative correlation?
No, it indicates an extremely strong positive correlation.
What does dispersion indicate about the data?
correlation which can be strong or weak
Would a 0.5 correlation be considered weak modest strong or very weak?
It really depends a lot on the context. The Cohen scale, for example, puts a correlation of 0.5 right on the cusp of "medium/modest" (0.30-0.49) and "large/strong" (0.50-1.00). However these cutoff criteria are largely arbitrary and shouldn't be applied too strictly. A correlation of 0.5 might be regarded as strong in some social science situations (e.g. where the measures are based on 5-point Likert scales) or weak in physical science situations where instrumentation can be extremely precise.
What is the correlation between smarts and niceness?
Smart is someone that knows a lot. Niceness is someone that is friendly to others. -------------------- Is someone smart more likely to be nice? Is someone nice more likely to be smart? Good questions! My hunch is that if there is a correlation, it would be a weak one.
