Answer:
1) d. observe phenomenon; generate hypothesis, conduct experiment, accept, reject, or modify hypothesis.
C. A study that compares a aroup of people with diabetes to a similar aroup of people without diabetes is an example of a case-control study.
Explanation:
Scientific method is a step by step procedure ranging from observing a problem to actual experimentation that aims at investigating a problem. The steps involved in the scientific method are as follows:
a)observe phenomenon; This precedes every experiment in the scientific method.
b) generate hypothesis: This is a testable explanation given as a possible solution to the observed problem.
c) conduct experiment: The hypothesis is tested via experimentation.
d) accept, reject, or modify hypothesis: Based on the result of the experiment, the hypothesis can be rejected, accepted or even modified.
Question 2:
Case control study is a type of study design that uses or compares a group of affected individuals (by a disease) called CASES and unaffected individuals called CONTROL. In this case, A study that compares a group of people with diabetes (cases) to a similar aroup of people without diabetes (control) is an example of a case-control study.
