MODULE 5: SAMPLE QUESTION 2 SOLVED

SAMPLE QUESTION 2

Imagine you are interested in looking at the differences between lecturers and students. You took a random sample of five Economics lecturers from the University of Lagos and five Economics students and then measured how many friends they had, their weekly alcohol consumption (in units), their yearly income and how neurotic they were (higher score is more neurotic). Enter the data in SPSS. These data are in Table 5.1:

PROCEDURES

Step 1: Open the SPSS, click the variable view.

Step 2: In the variable view window, under name type ‘Name’ as shown in figure 5.1.  you just created your first variable! Notice that once you have typed a name, SPSS creates default settings for the variable (such as assuming it’s numeric and assigning 2 decimal places). But we want to enter names of people, so will would change it to string.

                                                           Fig. 5.1

Step 3: Click the ‘type’ to change to string, when you click it, fig. 5.2 will display then click ‘string’ as shown in fig. 5.3 and ok. SPSS set the width as 8, so leave it since none of the name will want to enter have more than 8 characters.

                                                            Fig. 5.2

                                    Fig. 5.3

Step 4: Enter detail information of the variable ‘Name’, we can simply write ‘participant’s first Name’ in the column for label as shown in fig. 5.4

                                                           Fig. 5.4

Step 5: Specify the level of measurement. In this case, the level of measurement is nominal as explained in module 4.

Step 6: Move to data view and enter the names of the participant in the column of ‘Name’ as shown in Fig. 5.5.

Step 7: Click the variable view and type ‘Birth_Date’ in the second row as shown in fig. 5.6, and change the type to ‘Date’. as shown in fig. 5.7

Step 8: Click the data view and enter the date of birth of each participants as shown in fig. 5.8

                                                          Fig. 5.8

Step 9: Enter the variable ‘Job’ in the variable view, you can make a representation for simplicity, you can represent ‘Lecturer’ as 1 and ‘student’ as 2. As shown in figure. 5.9

Fig. 5.9

Step 10: Save your data, press ‘ctrl s’ and fig. 5.10 will be display, then enter the name you want to name it and click save.

Self-Test: Having created the first Three variables with a bit of guidance, try to enter the rest of the variables in Table 5.1 yourself.

SPSS BASIC OPERATOR

SPSS basic operator are mainly used with IF, DO IF and COMPUTE. They work mostly as you would expect but they do have a couple of surprises in store. it will be discussed in detail later.

That is how we come to the end of week 1, please ensure you attempt the quiz and feel free to ask any question. Next week we are moving to chi-square. so watch out and get prepared
