ALGEBRA 1 - MODULE 6: LESSONS 6.1 - 6.2 bivariate data - ANS-paired values of two variables correlation - ANS-the measure of the direction and strength of a relationship between two variables correlation coefficient - ANS-a statistic that describes how closely the points in a scatter plot cluster about a line extrapolation - ANS-the act of estimation by projecting known information interpolation - ANS-estimating a value within the range of measured data line of fit - ANS-a line that closely approximates a set of data scatter plot - ANS-A graph with points plotted to show a possible relationship between two sets of data. least-squares line - ANS-the line of fit for which the sum of the squares of the residuals is as small as possible linear regression - ANS-a statistical method used to fit a linear model to a given data set residual - ANS-The vertical distance between an actual data point and the predicted value of the function fitted to the data residual plot - ANS-a scatterplot of the regression residuals against the explanatory variable line of best fit - ANS-a smooth line that reflects the general pattern in a graph
