A measure of central tendency can be understood as a method that helps to determine the single value of the observation or distribution. This single value is the center or middle value of the distribution. Thus, we can say that measure of central tendency helps to compute the central value or average of collected data.

- Econometrics Thomas Eisensee and David Stromberg wanted to measure how much news coverage of a foreign disaster impacted the amount of disaster relief provided by the U.S. government. They argue that the simple relationship would be biased. Let X = Minutes of News Coverage and Y= Disaster Aid. Choose a variable X2 that could bias the simple relationship. This variable should impact the amount of coverage and impact the amount of aid for reasons other than purely news coverage. Eisensee and Stromberg introduce an instrument Z = During the Olympics. Explain how Z could satisfy the relevant and exogenous criteria. Explain how you could use Z to estimate the impact of X on Y free from X2 bias. Hint: you should mention two stages.How do you solve a problem similar to this? I’m confused on how to solve to find the quantity when you have the other variables.
