Biology IA Chi Square Test Help

Recommended Posts

Hi,

So for my processed data section for my IA, I have to do the chi square statistical test. What I don't understand is how am I supposed to get the expected value. For my IA, I collected data for the population of a species living in two different areas and hypothesis is that one area will have more than the other. So is my expected value supposed to just be a random value I make up?

Thanks in advance!
