In reporting the results of statistical tests, report the descriptive statistics, such as means and standard deviations, as well as the test statistic, degrees of freedom, obtained value of the test, and the probability of the result occurring by chance (p value). Test statistics and p values should be rounded to two decimal places. All
Reliability is the extent to which a second, third and onwards observations of an event, measure, rating, or occurrence, deviates from the first or proceeding observations. If they are exactly the same, there is perfect reliability. In engineering terms, reliability is referred to as repeatability.
