LAB ASSIGNMENT #1 Entering Data This assignment will use cars.sav , located on Canvas in the week 1 module. 1. Open the data file cars.sav . You are a researcher who wants to compare the mean miles per gallon (“mpg”) of cars that have different numbers of cylinders (“cylinder”). In this example, which variable is the DV and which is the IV? Create a new output file (File → New → Output). Then, click on Insert → New Text and write your answers in the box. (2 points) 2. Would “cylinder” be classified as a Categorical or Continuous variable? How would “mpg" be classified? In the output file, click on Insert → New Text and write your answers in the box. (1 point) Hint : Look at the definitions of categorical and continuous variables on slide 32 of the Week 1 lecture. What does each “unit” of the variable mean? 3. Open a new SPSS data file: File → New → Data. Enter the following data: Teaching Method Exam Scores Electric Shock 88 Electric Shock 95 Being Nice 80 Being Nice 45 Code Electric Shock as 0 Code Being Nice as 1. Complete both the Data View and Variable View. (2 points) HINT : “Coding” a variable means that you are creating categories within the variable. We want to tell SPSS that there are 2 categories for the Teaching Method variable. You can do this using the “Values” box that corresponds to the Teaching Method variable in Variable View (see slide 36 of the Week 1 lecture). ** To receive credit, save the output window for questions 1-2 as “ LastName_ Assignment_1a.spv” and the data viewer for question 3 as “ LastName_ Assignment_1b.sav” . Submit both files on Canvas.
