SOC350H5 Lecture Notes - Lecture 4: Interval Ratio, Scatter Plot, Dependent And Independent Variables
Document Summary
Cannot do reg unless dep variable is interval ratio. Regression line on graph that shows slop (relationship) Comparing effects of females against males and predicting outcome = ok. How to do regression when outcome is binary. Outcome if dep variable is interval then use regression. Graph that is associated with reg is scatterplot. Look at all points on data and see how dispersed they are. Every point in data represents x and y coordinates. The line is supposed to capture general pattern in data. Relationship between paying higher price to save env and country"s wealth. Every one unit increase in x (inequality), y increases by . 3 . Ordinary least sq related to line of fit. Every line can be equated to y=a+bx. You fit line to reduce total amount of error squared. Sq to accommodate for negative (points under line) Line of fit is line that reduces total number of error related to ordinary least sq.
