An Introduction to Psychological Statistics

Introduction to Psychological Statistics – We are constantly bombarded by information, and finding a way to filter that information in an objective way is crucial to surviving this onslaught with your san ity intact. This is what statistics, and logic we use in it, enables us to do.

Through the lens of statistics, we learn to find the signal hidden in the noise when it is there and to know when an apparent trend or pattern is really just randomness. The study of statistics involves math and relies upon calculations of numbers. But it also relies heavily on how the numbers are chosen and how the statistics are interpreted.
