Problem Set 2 - Quantitative Analysis

Below is a regression table. For this problem set, you will have to answer the following questions by identifying the main concepts within the table.

Before we get started, some variable context: Polity score is an indexed variable that social scientists use to interpret how democratic/autocratic a country is. This is scored from -10 (fully autocratic) to 10 (fully democratic). Legislative volatility is a measure of how often the legislature changes hands between parties. The other variables are straightforward, but if you have difficulty interpreting what they may mean, use your best judgement!
