Lab Report

Your lab report is due at the end of the week. In case you have any trouble with your HW tonight, I will give you an example of some experimental methods, to help you come up with your own.

Observation: Students like to have money in their pockets. Students don't get high test scores.

Problem: Students don't like studying for tests.

Hypothesis: If students are given $10 as a reward for good grades, then they will increase test grades.

Independent Variable: $10 reward for good grades
Dependent Variable: test grade

Experiment: Take ten students (group A - experimental group) out of the class and inform them that they will get $10 dollars i f their test grade goes up ten points or more for the next exam.

Take ten students (group B-control group) out of class and inform them that they will get personal satisfaction and pride if their test grade goes up ten points or more for the next exam.

Administer exam to the two groups of students.

Score exam, and record the results in a table/graph.

Conclusion: Based on the data results, confirm or reject your original hypothesis.

Further study: Maybe the students should not all come from the same class. If students feel it is unfair that they did not get $10, they might be angry and refuse to study for that reason. So make the sample of students more random. More students could be tested in more trials, to see whether the first trial had reliable results. So increase the number of trials.

Good luck, remember you can call me if you have problems.
