Range = value obtained by subtracting the smallest observation (sample minimum) from the greatest (sample maximum) * For the purposes of the AP Exam, students will not be required to perform calculations using this equation; however, they must understand the underlying concepts and applications.

2024年3月7日 · A .05 critical value represents that there is a 95% chance that the difference between the data you expected to get and the data you observed is due to something other than chance. In this example, our value will be 3.84.

The table below is a critical values table. Here’s how to use it. Critical Values Table. Determine the number of categories in your data set. In a genetics problem, that’s the number of phenotypes. Take the number of categories, and subtract 1. That’s your Degrees of Freedom (df) Find the table cell where probability (p-value) at the 0.05 ...

The table is used to decide whether to accept or reject a null hypothesis depending on the degrees of freedom (number of independent variables in the data) and the critical value (determines what makes results significant).

2020年4月29日 · The Chi-square test computes the difference between experimental (observed) and expected values for the different groups involved. These calculations yield the Chi-square. That value is then compared to a critical value.
