Experimantal Design
In this module you learned about different experimental designs. In this homework, for each scenario, you will
(1) identify a hypothesis (there may be more than one possible hypothesis and you only need to provide one hypothesis)
(2) identify the independent variable in your hypothesis
(3) identify the dependent variable in your hypothesis
(4) Describe an experimental design you will design to test your hypothesis
(5) Identify possible confounding variables (potential spurious factors):
You should be able to answer these questions for each of the scenarios in 2-3 pages (total).
1) You have been hired as a consultant by your city council to study the effects of a new initiative to combat COVID-19 vaccine hesitancy.
