How to calculate chi square genetics
WebE13. Let's suppose you conducted an experiment involving genetic crosses and calculated a chi square value of 1.005 . There were four flax rust. categories of offspring (i.e., the degrees of freedom equaled 3 ). disease. Explain what the 1.005 value means. Your answer should include the phrase " 80% of the time." WebIn addition to the significance level, we also need the degrees of freedom to find this value. For the goodness of fit test, this is one fewer than the number of categories. We have five flavors of candy, so we have 5 – 1 = 4 degrees of freedom. The Chi-square value with α = 0.05 and 4 degrees of freedom is 9.488.
