Document Summary

Soan 2120 introductory methods september 19th, 2017. Read chapter 4 in basics of social research (qualitative and quantitative approaches) Chapter 4 analysis of quantitative data: data coding means systematically reorganizing raw numerical data into a formal that is easy to analyze using computers. Independence (opposite of a correlation) the absence of a statistical relationship between two variables (ex: when knowing the values on one variable provides no information about the values that will be found on another variable). A high level of precision occurs when the points hug the line that summarizes the relationship. A low level occurs when the points are widely spread around the line: a bivariate table presents the same information as a scatter gram in a table format. It condenses information about a bivariate relationship into a single number: control variable third variable that shows whether a bivariate relationship holds up to alternative explanations.
