Jack Crevalle - No limits on size or number kept. We don't catch many of these fish, but we have caught a few big ones (10 lbs and up) over the years. The big ones hit mostly live bait, small ones will bite on just about any bait and the large ones put up quite a fight. They will also hit fast moving artificial baits.
Theoretically, the Spearman correlation calculates the Pearson correlation for variables that are converted to ranks. Similar to Pearson's bivariate correlation, the Spearman correlation also tests the null hypothesis of independence between two variables.
Being able to quantify the degree of co-variation, called correlation, helps leaders understand whether assumptions are on or off base. The word correlation does not imply or mean, causation. A correlation simply means that two measures tend to vary together. A perfect positive, one-to-one (1:1) correlation has a correlation coefficient of +1. A perfect 1:1 negative correlation has a correlation of -1.
