Chi squared?????

Hi,

This is the first chi sqaured test that i have done since ive been taught about it in a lecture. The lecturer isnt that good and neither is the notes that he has given out, so im a little unsure about something.

I have done a chi squared test on some data that has 9 degrees of freedom. The chi sqaured value that i get once ive added all the values together is 93.4. Looking at the chi sqaured table, i cant see any values near this value. So which do i choose?


Many thanks to anyone that can help me with this

Rob

Re: Chi squared?????

Could you publish your data table so that we can see that there are in fact 9 degrees of freedom and you have evaluated the statistic as 93.4 correctly. A statistic of 93.4 with 9df would indicate an extremely low probability that the null hypothesis is true.
