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 ...

So, we have a chi-square value that we calculated, called chi-square-calc (0.166) and a chi-square value that we looked up, called chi-square-crit (3.84). Comparing these two values, we find that our chi-square-calc is much smaller than the chi-square-crit (0.166 < 3.84), which means the deviations were small and the model fits the data.

df = (3 – 1)(3 – 1) = 4 ( 0.01 < P value < 0.02 (table). [P value = 0.012 (calculator).] Because P value < 0.02, we reject H0. We have strong evidence that the number of crimes committed is related to the temperature at the time of the crime. 4. A study yields a chi-square statistic value of 20 (χ2 = 20).

If the Chi-square value is greater than or equal to the critical value There is a significant difference between the groups we are studying. That is, the difference between actual data and the expected data (that assumes the groups aren’t different) is probably too great to be attributed to chance.

Step 6: Compare the calculated value for 2 to the critical value of 2. Look at a table of critical values of 2. Step 7: Decide to reject or not reject the null hypothesis. Calculated 2 < critical 2 → null hypothesis . not rejected. Calculated 2 > critical 2 → null hypothesis . is rejected. Critical 2
