What does it mean?
Espesially I'd like to know the meaning of 'statistically significant'.
Thanks. |

| Statistical significance is a technical term related to the measurement of sampling error.Usually, researchers are attempting to accept, or reject a null hypothesis. Tests of significance generally require probabilities that the "effect" measured is extremely unlikely to have occurred as a result of a sample (perhaps from a survey) differing by chance from the entire population that it is expected to represent. It does not address non-sampling error -- including many things like poorly designed questions, not identifying the relevant population to be polled, interviewer bias, etc. |
