Simple Linear Regression and Correlation
... • Develop a model that has a theoretical basis. • Gather data for the two variables in the model. • Draw the scatter diagram to determine whether a linear model appears to be appropriate. • Determine the regression equation. • Check the required conditions for the errors. • Check the existence of ou ...

... (or alternatively from the Regression data analysis). E.g., based on the data from Example 1, we have: GROWTH(B6:B16, A6:A16, 26) = 21.35 which is the same result we obtained earlier using the Regression data analysis tool. GROWTH can also be used to predict more than one value. In this case, GROWTH ...

... Probabilities in post-hoc tests are cumulative: e.g., three comparisons at 0.05 level produce a cumulative probability of type I error of 0.15. So: The probability of each test must equal α / the number of comparisons to preserve the overall significance level (Bonferroni correction). Example: If th ...
