You are supposed to assume/expect that nothing happens, or the norm happens. E.g. if you are testing if plants grow more in light, you assume they dont, then see if that expectation is consistent with the result.

When your experimenter results are not what you predicted what should you do?
Double-check your procedure and your lab technique. If they're still not what you predicted after eliminating any potential sources of error, then evidently you've learned that your initial premises were wrong, and you'll have to reject your hypothesis since you've proven that it's false.
Why hypothesis must be testable and falsiable but not provable?
So other scientists can test it out to confirm results. Theres no definite answer in science that's why its not provable, As fore falsible, idk what that means.
A scientific hypothesis that has stood the test of time is often referred to as?
A well tested idea that explains and connects a wide range of observations is a scientific theory. This is sometimes confused with a scientific law.
How did Oparin's hypothesis help Miller and Urey?
Miller and Urey set out to test a part of Oparin's hypothesis on the origin of life.
What do you have to do before you perform your experiment?
You want to have a hypothesis to test. A hypothesis is kind of like a reasoned guess what you expect to happen. The results of your experiment will either support your hypothesis or it wont.
How will test your hypothesis procedure?
Do your hypothesis, wrote down your results, and see if your right
What do scientist do after they have tested a hypothesis?
Depending on the results of that test, either accept or reject that hypothesis.
What is test data?
Results from a test. What you learned from the test/what you found, what was tested, hypothesis, etc.
Is a hypothesis is a decision based on the results of the experiment.?
No. An hypothesis is an idea put forward to explain an observation. Often you do the experiment to test the hypothesis. The results of the experiment may help you decide whether to discard your hypothesis or to test it further.
Why should an experimenter do after analyzing test results?
After analyzing test results, the experimenter should draw conclusions based on the data, determine whether the results support the hypothesis, and consider the implications of the findings. It is important to communicate the results clearly and accurately in a report or presentation to share the outcomes of the experiment with others.
What is A chi-square test of significance is essentially concerned with?
A chi-square test is often used as a "goodness-of-fit" test. You have a null hypothesis under which you expect some results. You carry out observations and get a set of results. The expected and observed results are used to calculate the chi-square statistic. This statistic is used to test how well the observations match the values expected under the null hypothesis. In other words, how good the fit between observed and expected values is.
Why do you test hypothesis?
So you know whether it is valid or not. If it isn't modify your hypothesis to fit the results of your experiments.
How would you test for your hypothesis?
You would test your hypothesis by predicting what the results of your experiment will be so it's like a type of prediction. Another way is what do you think the outcome will be.
Reject or accept null hypothesis F-test?
Using the data in the Excel file Consumer Transporta
What are the steps in a science fair project like hypothesis conclusion and others?
ask the question backround research construct hypothesis test with an experiment analize results report results
What do you do to test a hypothosis?
First you ask a question about what you want to learn, Then you do some research, Next you construct a hypothesis, Then you test the hypothesis by doing an experiment, Next you Analyze your data and draw a conclusion, Communicate your results. And that is the hypothesis.
