Inference, in statistics, the process of drawing conclusions about a parameter one is seeking to measure or estimate. Null hypotheses, Student's t-test, p-values these terms get thrown around a lot without explaining their underlying probabilistic basis 9. PROCESS OF TESTING HYPOTHESES A. False-Positive and False-Negative Errors 1. Inferential Statistics is the process of examining the observed data (sample) in order to make conclusions about properties/parameter of a Population. Test Alternative Hypothesis with Statistical Test (2 sample T test can be used here) Based on the test result, reject or accept the null hypothesis Ho; Now that we have formed the hypothesis, we have to decide the statistical test which we need to perform to test the hypothesis. Bayesian inference is one proposed alternative to significance testing. The American Psychological Association has strengthened its statistical reporting requirements after review,[69] medical journal publishers have recognized the obligation to publish some results that are not statistically significant to combat publication bias[70] and a journal (Journal of Articles in Support of the Null Hypothesis) has been created to publish such results exclusively. H Philosophers consider them separately. Statistical tests show whether an observed pattern is due to intervention or chance. The handful are the sample. Assess the statistical significance by comparing the p-value to the α-level. A hypothesis test specifies which outcomes of a study may lead to a rejection of the null hypothesis at a pre-specified level of significance, while using a pre-chosen measure of deviation from that hypothesis (the test statistic, or goodness-of-fit measure). On the other hand, if the null hypothesis predicts 3 counts per minute (for which the Poisson distribution predicts only 0.1% chance of recording 10 or more counts) then the suitcase is not compatible with the null hypothesis, and there are likely other factors responsible to produce the measurements.
