Document Summary
Most common form of political science research. Uses statistics (the computer does all the work! ) to see if there is a statistically significant relationship between our variables. 2 key types measures of central tendency and dispersion. Is the value of the case (remember unit of analysis - individual, city, country, etc) that sits at the exact center of our cases when we rank them from the smallest to the largest observed value. The centermost ranked cases divided by 2. If we have an even number of cases then the median is the sum of the two. For or woman, or jew or muslim. We must set the mode as our measures of central tendency. These variables have no order to rank to find median. It would not make sense to take an average of sex or religion - one is either man. The median tells us more about a typical cases than the mode.
