For this discussion, identify three different variable pairs in which two quantities appear to be related from either recent news stories, the web, or that you encounter in your everyday life. Each variable pair should come from a different source (as illustrated in the week 4 Discussion Sample.. It’s attached) and there should be three sets of paired variables total. Important note: Only one of the variables can use “time” as an independent variable. For example, you cannot have your variable pairs be (time, dependent variable 1), (time, dependent variable 2) and (time, dependent variable 3). However, you can have your variable pairs be (time, dependent variable 1), (independent variable 2, dependent variable 2) and (independent variable 3, dependent variable 3). For inspiration, use the examples listed in the solution to Example 1 on the Week 4 Discussion Sample. Be sure to select different examples! Create Table After you have identified three different variable pairs (from distinct sources), make a table of between 10 and 20 entries of data values for each of your variable pairs. Create Graph Then, graph your data values for each variable pair and describe in words the function that relates the variables. For each pair, write down at least five (5) points on the graph. Draw the graph using paper & pencil or use an online graphing calculator like Desmos Graphing Calculator Describe Your Results in Words For each of the pairs you listed, identify the dependent and independent variables and briefly describe the relationship. See the week 4 Discussion Sample to see how these go (You must use different examples; you should complete three examples total). Your initial post should be at least 250 words in length. It should show all the required math work and explain all the steps. Also include a simple reference for any scholarly resource you used. For example: Washington Post dated August 13, 2018 The Easy Way to Plot and Graph Points Use the Desmos Graphing Calculator Click on the “+” at the top left corner. Select “table” from the drop-down menu. Type in your points. If your point is (2, 30), then x1 is 2 and y1 is 30. ** If your points contain any values beyond ±10, click the minus sign in the upper right-hand corner a few times to zoom out so you can see the points. ** To add a line connecting the points: Click and hold on the circle with four dots on it (next to y1). Click the circle next to “Lines” to show the connecting line. Your graph is done. To share the graph, take a screenshot. Alternatively, click on the arrow in a box at the upper right hand corner of the screen, then you can “Export Image” as a .png file (it appears in your “Downloads” folder) and attach this to your discussion post or drop and drag into a Word file.
