Question

Problem Set 4 DUE: 11/1/2017 ECON300 Suppose that you are asked to conduct a study to determine whether attending lectures has an effect on student performance in ECON300. 1. [5pts] If you could conduct any experiment you want, what would you do? Be specific. Explain why your proposed experiment may or may not be practical and/or ethical in reality. a. b. [5pts] More realistically, suppose you can collect observational data based on everyone enrolled in the course. You obtain data on the percentage of lectures attended, and the final course mark in numeric form. Would you expect a positive or a negative correlation between these two variables? c. [5pts l Suppose the data shows that the variables are positively correlated. Is this proof that attending lectures causes students to perform better? Explain why or why not.

Explanation / Answer

Steps in conducting experiment:

1.Main objection should be clear

2.Design the experiment

3.Collection of data

4.Analyzation the data

5.interpretation of data

Experiment practice may or may not be ethical it depends on how we are conducting the experiment i.e,, whether we are following ethical principles are not.

b)Yes,I expect a positive or negative correlation between those two variables.Because,there should be some relation in the two given variables.

c)Yes.Because correlation gives the relationship between two variables.if the data shows that variables are positively correlated then this proof is more than enough to conclude that attending lectures causes students to perform better.
