Document Summary

The purpose of this course is to provide an introduction to research methodology in the social sciences. This class will cover both qualitative and quantitative approaches to social research. Experiments very controlled environment pretest, treatment, post-test. Survey ask them a number of q s do not manipulate subjects each question on survey represents a variable. Quantitative variables continuous (rank), numerical (e. g. education #of years of schooling and income # money) Categorical non-rank order, non-numerical (e. g. religion catholics do not rank higher than protestants and race skin colour) When the mean is equal to the median (the average is equal to the middle), this is a normal distribution. Normal distributions allow us to conduct significance tests. The distribution of a variable using data from our sample is called sample distribution. The distribution of the variable in the population is called population distribution. The distribution of the mean of a variable from all possible samples is the sampling distribution.
