Document Summary
The key element of statistical imagination is the analysis if cause and consequences with the goal to predicting future events. The test estimate of a dependent variable can be imposed if we can identify independent variable and extend the analysis to the bivariate level. correlation: is a systematic change in the scores of 2 interval ration variable (when the change in one variable change in tandem with the measurement of the other) 2 variable correlated if their measurement consistently change together form case to case. simple bivariate linear correlation and regression analysis: procedure of improving best estimate of y by accounting for its relationship with. scartterplot: a two-dimensional grid of the coordinate of two interval-ration variables x and y. coordinate: a point on a scatterplot where the values of x and y are plotted for a case. Linear patterns: on where the coordinate of the scatterplot fall into a shape of a straight line.
