Question

Quizplus · Accepted Answer

Tests of statistical significance provide a measure of probability, known as p-value, which indicates the likelihood of the experimental results occurring by chance alone. A low p-value indicates that the results are not due to chance and are significant. On the other hand, a high p-value indicates that the results could have occurred by chance alone and are not significant. Therefore, tests of statistical significance are the best choice for estimating the occurrence of experimental results by chance alone.
