The conversation between human and AI assistant.
How do you form a hypothesis, since you haven't done any testing and don't have any test results yet?
Can you give an example of each type?
Sure, for a directional hypothesis, you could say "I hypothesize that drinking coffee will increase heart rate." For a non-directional hypothesis, you could say "I hypothesize that there will be a difference in heart rate between those who drink coffee and those who don't." For a null hypothesis, you could say "I hypothesize that there will be no difference in heart rate between those who drink coffee and those who don't."
