Write about some research idea and specify independent and dependent variables.
1. Say which variable you use as intrument variable to solve the endogeneity problem
2. say how to specify the DID framework to do the research
3. how you can use Regression Discontinuity Design method to do your research.
ANY correct example will be fine.

Given the research questions below, state the
independent and dependent variables (or Variable 1 and Variable 2)
and level of measurement. Write null and research/alternative
hypotheses. Then conduct the appropriate statistical analysis.
State tests used, report and interpret key statistics, and explain
your findings, including the likelihood you might be committing
Type I or II errors given your decision regarding the null
hypothesis.

Refresher on Variables:
Classifying variables as independent or dependent:
The independent variable is the one being
manipulated or grouped in the study for comparison. A tip to
remember this is to think that independent starts with “I” and I,
the researcher, manipulate that variable or have control over who
is grouped in the study. The way we will be using independent
variables in this course is in terms of between group analysis, so
our focus will be on groups being...
