Experiments
Research suggests that if students use laptops in class, it can have some effect on student
achievement. While laptop usage can help students take lecture notes faster, some argue
that the laptops may be a source of distraction for the students. Suppose you are interested
in looking at the effect of using laptops in class on the students' final exam scores out of 100.
You decide to conduct a randomized control trial where you randomly assign some students
at UIC to use a laptop in class and other to not use a laptop in class. (Assume that the classes
are in person and not online)
a. Which people are a part of the treatment group and which people are a part of the
control group? (10 points)
b. What regression will you run? Define the variables where required. (10 points)
Dummy variables
News reports claim that in the last year television watching has increased. You believe that
rising unemployment during Covid may be one of the causes for this. Suppose you are
interested in looking at the effect of being unemployed on the hours spent watching Netflix
per day. You collect data on 10,000 people from Chicago who are between the age of 20 and
60. You define the dummy variable Unemployed which takes the value 1 for those who are
unemployed and 0 for those who are employed.
Equation 1:
Hours spent watching Netflix₁ = ßo + B₁Unemployed; + ε¿
Following is the output for equation 1:
