Throughout the chapter, students are asked to create a scatter plot of a given data set and analyze the scatter plot to determine if there is an association between two variables. What is a positive correlation? scatter plots and frequency tables . It represents data points on a two-dimensional plane or on a Cartesian system.The variable or attribute which is independent is plotted on the X-axis, while the dependent variable is plotted on the Y-axis. points from values of two variables) that exhibit one or more key features (e.g. Data plots that form total cost vs month of regression data show a linear relationship and that costs are going downward. Description Also known as a Scatter Graph, Point Graph, X-Y Plot, Scatter Chart or Scattergram. Starting the axis above zero truncates the visualization of values. If the points are coded (color/shape/size), one additional variable can be displayed. Things to look for: The given information includes a scatter plot showing two variables, say x and y.
