... Find the "area beyond z", using a table of areas under the normal curve (such as the one on my website). The area beyond z = 0.0099. In other words, values of W as large as ours are likely to occur by chance with a probability of 0.0099. This is the one-tailed probability of obtaining W however; we ...

Note that a high degree of correlation does not imply anything about a causal relationship between x and y, but what it does do is enable one to predict values of y from x with a high degree of probability that they will be co ...
