To check if the result is statistically significant, the calculated chi-square value and the degree of freedom are analyzed on the probability chart under α=0.05. The value from the table is 3.841. Since the chi-squared value 9.69 is greater than 3.841, we have statistically significant ...
Hi all, I'm a high school physics / AP biology teacher looking to expand my understanding of the Chi-square test some. I planned an activity in which students are randomly drawing colored marbles out of a bag in order to see if they match predicted ratios (2:1, 1:1, o...
Chi Square (X 2) Modeling Using Candy [Google Doc] The Chi Square test is often used in science to determine if data you observe from an experiment is close enough to the predicted data. In genetics, for instance, you might expect to get a 75% to 25% ratio if you crossed two ...
