If your exact chi-square value is not listed in the table, then estimate the probability. The estimated p-value is _____. Notice that a chi-square value as large as 1.61 would be expected by chance in 90% of the cases, whereas one as large as 15.09 would only be expected by chance in 1% of the cases.

The chi-square critical values table provides two values that you need to calculate chi-square: • Degrees of freedom. This number is one less than the total number of classes of offspring in a cross. In a monohybrid cross, such as our Case 1, there are two classes of offspring (red eyes and sepia eyes). Therefore, there is just one degree of ...

The Chi-square value is a single number that adds up all the differences between our actual data and the data expected if there is no difference. If the actual data and expected data (if no difference) are identical, the Chi-square value is 0. A bigger difference will give a bigger Chi-square value. 4. Look up the Chi-square value in a table to ...

The Chi Square test (X2) is often used in science to test if data you observe from an experiment is the same as the data that you would predict from the experiment. This investigation will help you to use the Chi Square test by allowing you to practice it with a population of familiar objects, M & M candies.
