Chi- Squared Flashcards
Observed data
Collected in field or secondary source
Expected
Expected according to the theoretical hypothesis
Null hypothesis
No significance different between the O and E data
What must you remember to do ?
Minus 1 from total cateorgors
2 levels of aognicant
95% - 0.05
99% - 0.01
Your value is greater than critical value
Reject the null hypothesis and accept my alternative hypothesis that there is a aignicant different between variables.
I can say with more than 99% convince that there is a significant different and as there is a less than 1% chance my results are due to chance.
It’s it overall clears that ….
Your value is lower than critical value
Accept null hypothesis.
And reject the alternative hypothesis that there is no sigbicsnt different between the variables.
As there is more than a 5% chance that my results are due to chance.
It’s is clear that this variable affects this and I would have to conduct more research
