ONLY THE BLUE HIGHLIGHTED QUESTIONS! Thank you
In a testing experiment: a. What is the difference between a hypothesis and a prediction? b. How do you decide if the outcome of the experiment is/is not consistent with the prediction? c. How do you make a judgment about the hypothesis? How do the assumptions you made in your method enter into making this judgment? Describe the purpose of asking the following questions: What quantities can be used as independent variables? How will other quantities depend on each independent variable when all the other independent variables are kept constant? Come up with a specific situation in which the above questions would need to be considered.Explanation / Answer
1:
A hypothesis is a possible explanation for a observation or problem that can further be tested by experimentation. Hypothesis' are also known as educated guesses.
Difference:
Hypothesis could be used to describe a phenomenon that may be either a future, or past happening whereas a prediction is always used to describe future happenings.
• Hypothesis is based on evidence while prediction is based on experience and knowledge.
• Hypothesis has more scientific sense than prediction.
• A prediction could be respected or disrespected based on the occurrence of the event, whereas a hypothesis is always respected.
• Hypothesis has an explanation but prediction does not.
• Formulation of a hypothesis takes a longer time compared to that for a prediction.
• Hypotheses are usually longer statements than predictions are.
B)
We can use the test data or test results to check for the consistency of the the predicton.If the test data/results match with the predictions , then it is consistent , otherwise not
C)
Anything taken for granted is an assumption, and a hypothesis is at best a working assumption .
2) Any variable , that does not change its value because of change done in other variable/quantity can be used as an independent variable.
Other quantities will change if the independent variable is changed(example: if I change the refractive index or focal length(both can be taken independent variable),the values for image position will change
Any scientific setup can be used for the above setup , lets again take the setup for image formation through a convex lens
