group+DRFIT+chi+sqaured!

we would expect to find the same number of each snail colour in each of the two sites, since our null hypothesis states that there will be no difference between the frequencies of the different snails between the two sites. the chi squared results are shown below in two tables. the first is for woodland and the second for clear land:

therefore, the overall chi squared values for both tables above would be 5.2 and 9.6 for woodland and clear land respectively.
