Observed value o Expected value e Deviation o e or d Deviation d d e Smooth Rough Smooth Rough Chi square X d e If you have a ratio of 9 3 3 1 then to calculate the percentage you have to add the total sum of the groups 16 and that is your denominator and then each group is the numerator For example 9 16 is 56 3 16 is 19 3 16 is 19 and 1 16 is 6 which equal 100 12 What is your p value Notes regarding calculating the chi square number Obtain your observed values from Table 5 Calculate your expected e values based on your predicted phenotypic ratio and using the total number of kernels calculated in Table 5 Use your X number to determine your p probability value Use the Chi square table Table 4 to assist you in your calculations 11 What is your degree of freedom value 13 What are your conclusions based on your calculations Based on your experiment state which phenotypes are dominant and which are recessive Are there any significant differences between your observed and expected values and is your hypothesis supported
