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

In measuring substances in the lab‚ reporting data‚ and performing calculations‚ it is both crucial important to be as precise and accurate as possible and also not to report false data. The rules of significant figures (digits in a measurement that reflect the measurement’s accuracy) allow us to have a methodical means of ensuring that the data and calculations we report reflect the accuracy that the equipment or data provide. To follow the guidelines for the correct number of significant figures

Determination of Heat Capacity In this experiment‚ an improvised calorimeter was used to determine the heat capacity. The calorimeter weighed 4.47 grams prior to the addition of water. Tap water‚ 40 mL to be exact‚ was added to the calorimeter which increased the weight to 43.87 grams. The water was measured using
