To determine when using a z-test is more appropriate than a t-test you first
have to understand the difference between a z-score and a t-score. A zscore is a measure of how many standard deviations below or above the
population mean a measured

Correlation is a statistical measure that indicates the extent to which two or
more variables fluctuate together. A linear correlation indicates a very strong
correlation, however no matter how strong the correlation, correlation is not
the same
