The Chi-Squared Test Lies, More Lies, and… the χ 2 Test. Despite the misuse and abuse they get in everyday life, when you're studying genetics, statistics really are helpful, particularly when trying to figure out if your genes are behaving in the way you think they should be. Tips from Past AP® Biology Students. 1. Do lots of genetics practice problems. Practice working with Hardy-Weinberg formulas, Punnett Squares, and Chi-Square tests. Also, memorize the common crosses, like dihybrid monocross. 2. For test prep, use the released exams!

Chi-square in biology: Testing for a dihybrid ratio . You may have noticed we haven't talked about using chi-square in biology yet. We're going to do that now. In biology you can use a chi-square test when you expect to see a certain pattern or ratio of results. For example: you expect to see animals using different kinds of habitats equally

it would be expected that 314 would be purple and 314 would be yellow. The chi-square value is calculated below. The acceptable answer for this question should be 1.4.

Essential Knowledge + Science Practice Requires more reading than in previous exams (paragraphs, diagrams, data analysis) Grid-In (6 questions) Integrate science and math skills Calculate correct answer and bubble in the grid Bring a four-function calculator (with square root) to use on the exam A formula list will be provided for the exam So $\chi^2$ test can be used for categorical data but it is not the only test. Bottomline: a statistic tested by a $\chi^2$ test has $\chi^2$ distribution as its sampling distribution. That statistic should be a square/sum of squares- something that can never possibly have a negative value. Perhaps that is why it is called $\chi$ squared.
