COrrelations
Determining the Statistics
Using a confidence interval at p = 0.05 I am able to be 95% confident that the independent variable is responsible for the differences observed. Also, with 40 degrees of freedom (using my 40 zip codes) I had a correlation coefficient of 0.304. Therefore, should the calculated correlation value for each demographic exceed 0.304 or -0.304 (to a more negative point), I could deem that correlation a significant positive or negative correlation, respectively. Above are links to the X-Y Scatterplots for the various correlations investigated.
