    Intro to Stats Q1: Q2: [3-6] Correlation is a measure of the direction and strength of the linear (straight-line) association between two quantitative variables. The analysis of data from a study found that the scatter plot between two variables, x and y, appeared to show a straight-line relationship and the correlation (r) was calculated to be -0.84. This tells us that there is little reason to believe that the two variables have a linear association relationship all of the data...

    Most graphs in economics are based on a grid bordered on the left and below by two perpendicular lines that show the values of two variables: x and y. One variable is called the x-variable and the other is called the y-variable. The solid horizontal line at the bottom of the graph is called the horizontal axis or x-axis, and values of the x-variable are measured along it. Similarly, the solid vertical line on the left of the graph is...
