The chi-square test is always testing what scientists call the null hypothesis, which states that there is no significant difference between the expected and observed result. For example, suppose that a cross between two pea plants yields a population of plants, with green seeds and with yellow seeds. You are asked to propose the genotypes of the parents. Your hypothesis is that the allele for green is dominant to the allele for yellow and that the parent plants were both heterozygous for this trait. If your hypothesis is true, then the predicted ratio of offspring from this cross would be based on Mendel's laws as predicted from the results of the Punnett square Figure B.

Figure B. Predicted offspring from cross between green and yellow-seeded plants. To calculate 2 , first determine the number expected in each category. If the ratio is and the total number of observed individuals is , then the expected numerical values should be green and yellow. Chi-square requires that you use numerical values, not percentages or ratios. Then calculate 2 using this formula, as shown in Table B. Note that we get a value of 2. But what does this number mean? Here's how to interpret the 2 value: 1. Determine degrees of freedom df. Degrees of freedom can be calculated as the number of categories in the problem minus 1. In our example, there are two categories green and yellow ; therefore, there is I degree of freedom. Determine a relative standard to serve as the basis for accepting or rejecting the hypothesis.

The p value is the probability that the deviation of the observed from that expected is due to chance alone no other forces acting. Refer to a chi-square distribution table Table B. Using the appropriate degrees of 'freedom, locate the value closest to your calculated chi-square in the table. Determine the closestp probability value associated with your chi-square and degrees of freedom. In terms of your hypothesis for this example, the observed chi-squareis not significantly different from expected.
