Simple linear regression hypothesis
Webb9 sep. 2024 · Key steps to perform hypothesis test are as follows: Formulate a Hypothesis Determine the significance level Determine the type of test Calculate the Test Statistic values and the p values Make Decision Now let’s look into the steps in detail: Formulating the hypothesis One of the key steps to do this is to formulate the below two hypotheses: WebbSimple linear regression allows us to study the correlation between only two variables: One variable (X) is called independent variable or predictor. The other variable (Y), is known as dependent variable or outcome. and the simple linear regression equation is: Y = Β0 + Β1X Where: X – the value of the independent variable,
