Chapter 5 Bivariate Data­ two variables for on individual to find a relationship between one another When analyzing describe each variable and describe the relationship Explanatory variable­ X, used to predict, independent Response variable­ Y, dependent Scatterplot­ the variables measured by the same individual Linear relationship­ straight line Non­linear relationship­ a relationship but not at all a straight line Positive­ Y increases as x increases Negative­ Y decreases as x increases Correlation Coefficient­ calculate r, measures the strength of the linear relationship, strength plus the direction the graph is going Cross Product­ Sxy the sum of the relationship, when the variables are not related, or when both have a positive or negative relationship How outliers are effective­ creates a weaker correlation, effects the standard deviation of x from the mean meaning that the correlation coefficient decreases Lines­ Ŷ= ßo (y­int)+ß1x (slope) Regression line­ best fit line Predicted value­ y predicted value y for given value x Residual­ how much we miss by, actual value y­ predicted value Slope­ not scale free, decrease and increase of y, can predict y when x increases Y­intercept­ when x is 0 you can predict y, which cancels out the equation
