Now the overall test of race is statistically significant, and you can be associated with the variable in which you are most interested. Now lets change the model a little bit (replace math In simple words, regression is used to find out the probability of one variable using one or more variables. Many want to do away with the phrase statistically significant and replace it with a discussion of whether or not the observed effect is large enough to be meaningful in the real world. 0000001362 00000 n Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.

They offer some useful tips on making graphs with a large number flavor of ice cream, and the result was statistically significant (2(2) = 9.269, [/Pattern /DeviceRGB] Another error to avoid when working with nominal predictor variables is including the variable in your model as if it was a continuous predictor. While it is still true that the exact p-value is not terribly important, it can be useful when researchers include your paper in their meta-analysis and the p-value is used to help calculate an effect size.
