Biology 1011 midterm Questions and
All Correct Answers.
Scientific Method - Answer A series of steps followed to solve problems including collecting
data, formulating a hypothesis, testing the hypothesis, and stating conclusions.
1. Identify the problem - Answer An observation of the natural world
2. Building a hypothesis - Answer Pose a specific explanation for the observation (a question)
3. collecting data - Answer Evaluate the hypothesis, usually involves conducting an
experiment
4. Analysis - Answer analysis the data for the support or rejection of the hypothesis. this step
usually involves a statistic analysis that will lend confidence to the conclusion to be drawn from
the experiment
5. Conclusion - Answer Repeat steps 2-4 until a reasonable conclusion can be drawn. you
may have to modify your original hypothesis or develope a new one
What is the difference between a hypothesis and a theory? - Answer An hypothesis is a
guess whereas theories are generally considered fact.
Place the following steps in a sequence:
A) recognizing a problem
B) Testing a hypothesis
