Critical Thinking Lab For Chapter 6
MAT 143 Lab – Critical Thinking Assessment
The exam grades for a MAT 143 midterm exam are given below. The professor is trying to determine if she should curve the grades or not. The professor wishes to find the best measure of center to represent the exam scores so that she can make an informed decision. Consider the various measures of center and scenarios when each would be the best measure of center. What would be the best measure of center and why? Using the best measure of center, should the professor curve the scores?

Write up a solution that contains the following elements.
1. Clearly define the problem in complete sentences.
2. Identify the various strategies (techniques discussed in 6A for finding measures of center) you could use to solve the problem.
3. Now choose one of these strategies and perform the necessary calculation. Explain in complete sentences why you have chosen this strategy.
4. Answer the problem in complete sentences.
5. Reflection on the problem and strategy you took. Would you revise your approach if you did the problem again? Other observations?
