Trade-off between Type 1 and Type 2 errors. What are Type 1 and Type 2 Errors? Before we try and remember Type 1 and Type 2 errors, it is good first to understand the concept. In statistics (and in life), we often start with a null hypothesis (a belief we hold) and test it u...
The problem is, marketers often assume testing in itself is enough to negate the impact of personal bias, even as many brazenly ignore the statistics behind running a valid test.

For canonically arranged tables, circumstances are defined for which it is shown that the sign of (G2-χ2) is determined by the sign of the difference, (O11-E11), between the observed and expected numbers in the upper left cell. An analogous result for the tests of the null hypothesis...
This calculator will determine whether two correlation coefficients are significantly different from each other, given the two correlation coefficients and their associated sample sizes. Values returned from the calculator include the probability value a
Another way to think about the difference between a statistic and statistics is by considering the broader picture. If you have a set of numbers, each individual number can be a statistic. But when you collate all these numbers, analyze them, and derive meaningful insights, you are dealing wi...
