An extremely low p value indicates high statistical significance, while a high p value means low or no statistical significance. The p value determines statistical significance. A corresponding p value that tells you the probability of obtaining this result if the null hypothesis is true.A test statistic that indicates how closely your data match the null hypothesis.H a : Actively smiling leads to more happiness than not smiling.H 0: There is no difference in happiness between actively smiling and not smiling.To begin, you restate your predictions into a null and alternative hypothesis. Example: Formulating a null and alternative hypothesisYou design an experiment to test whether actively smiling can make people feel happier. Based on the outcome of the test, you can reject or retain the null hypothesis.

Using this procedure, you can assess the likelihood (probability) of obtaining your results under this assumption. Hypothesis testing always starts with the assumption that the null hypothesis is true.

An alternative hypothesis ( H a or H 1) states your main prediction of a true effect, a relationship between variables, or a difference between groups.A null hypothesis ( H 0) always predicts no true effect, no relationship between variables, or no difference between groups.To begin, research predictions are rephrased into two main hypotheses: the null and alternative hypothesis. This is a formal procedure for assessing whether a relationship between variables or a difference between groups is statistically significant. In quantitative research, data are analyzed through null hypothesis significance testing, or hypothesis testing. How do you test for statistical significance?
