Simple directional hypothesis
Webb10 mars 2024 · Whenever we perform a hypothesis test, we always write a null hypothesis and an alternative hypothesis, which take the following forms: H0 (Null Hypothesis): Population parameter =, ≤, ≥ some value. HA (Alternative Hypothesis): Population parameter <, >, ≠ some value. Note that the null hypothesis always contains the equal sign. WebbA statistical hypothesis is a hypothesis about a particular model parameter or a set of model parameters. Most often, such a hypothesis concerns one parameter, and the assumption in question is that this parameter takes on a specific value, or some value from a specific interval.
