![]() Seem like there's any obvious trend over here. Right place, and then we can move it if we want-Ĩ7, right over there. Is on the horizontal, the thing that's being drivenĩ3- right over there. This exploration she's doing, she's trying to see, well,ĭoes the period of the day somehow drive average score? So that's why Period is Least, just based on her data, see if- well, definitelyĭo what they're asking us, plot a scatter plot, and then And we have to be a littleĬareful with the study- maybe there's someĬorrelation depending on what subject is taughtĭuring what period. And then they give us theĪverage score on an exam. The period of the day that the class happened. She collected data aboutĮxams from the previous year. The independent variable can be whatever you like and the dependent variable is a result that depends on the independent variable.Ī connection between the time a given exam takes place and One where you input 1 and get an output of 2, you input 2 and get 4, you input 3, an get 9, and so on. ![]() You can also think of it as a number machine game. The dependent variable can jump around, like 9.2, 7, 5.3, 6.5. The independent variable is usually whole numbers, such as 1,2,3,4,5,6,7. If it didn't, here are some clues to help you find the variables: The number of miles that you drive would be the independent variable you have not driven x miles because you lost gas. In the real world, there are always sets of data that need to be interpreted. You want to see how the number of miles that you drive effects the gas in the tank. These include Scatter Plots, Correlation, and Regression, including how to use the Graphing Calculator. I know that it is long, but I hope it helps! : ) I also have some of my own examples and explanations below. The y-axis has the dependent variable which is a result of the independent variable. The x-axis always shows the independent variable, a number that is unaffected by what is on the y-axis.
