3 Choose variable view by clicking this button

4 Type the name of the variable here

5 Lets assume our first variable is Gender The variable name Gender has been typed

7 Type a label for this variable, e.g. Gender of Respondent* *Note: It is not necessary to provide a label for the variable. It serves to remind the researcher about the variable if a label is provided

8 1. Click Values 2. Click this sign to assign the Value Labels of the variable 4. Click add 3. Type 1 here, then Male here Assuming we have the following coding scheme for Gender 1.Male 2.Female

9 After Add is pressed the value label 1 = Male is transferred here

10 1. Type 2 3. Press Add 2. Type Female

11 2. Press OK to execute the process 1. The value label 2 = Female is now here

12 The process of defining the first variable Gender is now completed. Press the 1 st column of the 2 nd row to define the 2 nd variable Lets say the 2 nd variable is Age

13 Type Age

14 Under the Label type Age Group of Respondent

15 Assuming we have the following coding scheme for Age years years years years years and above

16 2. Type 1 for Value 1. Press here to define the value labels 4. Click Add 3. Type years for Value Label Repeat Steps 2, 3, 4 for the remaining value labels: Value 2 ; Value Label years Value 3 ; Value Label years Value 4 ; Value Label years Value 5 ; Value Label 41 and above

17 Press OK after all the value labels for Age have been defined

19 Lets move to the third variable. Assume that the next item in the questionnaire asks respondent to indicate his/her degree of agreement to the following statement: I enjoy my Business Research Methods class 1. Strongly Disagree 2. Disagree 3. Undecided 4. Agree 5. Strongly Agree

20 I have chosen BRM1 as the variable name to indicate that it is the first question related to Business Research Methods. It is arbitrary, we can also use other names.

21 Under the Label give a short descriptive label for the variable, e.g. Enjoy BRM

22 1. Press here to define the value labels for BRM1 3. Press Add 2. Type 1 for Value, and type Strongly Disagree for Value Label

23 B Press OK to execute A Repeat the process for the remaining value labels of BRM1, i.e. 2. Disagree 3. Undecided 4. Agree 5. Strongly Agree

24 The variable BRM1 and its value labels are now defined

25 Now let us practice some data entry with SPSS Assume we have received ten completed questionnaires from our respondents. Respondent 1 with the following responses: Female (2) years (2) Agree (4) Value labels for Male and Female in variable Gender Respondent 2 with the following responses: Male (1) years (3) Disagree (2) Respondent 3 with the following responses Female (2) years (3) Strongly Agree (5)

26 Now let us practice some data entry with SPSS Assume we have received ten completed questionnaires from our respondents. Respondent 1 with the following responses: Female (2) years (2) Agree (4) Value labels for Age Groups in variable Age Respondent 2 with the following responses: Male (1) years (3) Disagree (2) Respondent 3 with the following responses Female (2) years (3) Strongly Agree (5)

27 Now let us practice some data entry with SPSS Assume we have received ten completed questionnaires from our respondents. Respondent 1 with the following responses: Female (2) years (2) Agree (4) Value labels for the degree of agreement in variable BRM1 Respondent 2 with the following responses: Male (1) years (3) Disagree (2) Respondent 3 with the following responses Female (2) years (3) Strongly Agree (5)

28 Respondent 4 Male (1) 41 years and above (5) Agree (4) Respondent 5 Female (2) years (3) Strongly Agree (5) Respondent 6 Male (1) years (1) Disagree (2) Respondent 8 Female (2) years (1) Strongly Agree (5) Respondent 9 Male (1) years (3) Disagree (2) Respondent 10 Female (2) years (2) Agree (4) Respondent 7 Male (1) years (2) Agree (4)

29 To start entering data, we need to switch to the Data View Switch to the Data View by pressing this button

30 Type the values of the responses for Respondent 1 (Row 1) for the three variables (Gender, Age, and BRM1) Respondent 1 with the following responses: Female (2) years (2) Agree (4)

31 Respondent 2 is in Row 2 Respondent 2 Male (1) years (3) Disagree (2)

32 Respondent 3 Female (2) years (3) Strongly Agree (5) Respondent 4 Male (1) 41 years and above (5) Agree (4) Repeat the process for all the remaining respondents. Respondent 9 Male (1) years (3) Disagree (2) Respondent 10 Female (2) years (2) Respondent 5 Female (2) years (3) Strongly Agree (5) Respondent 6 Male (1) years (1) Disagree (2) Agree (4) Respondent 7 Now, the data entry process for Male (1) years (2) the 10 respondents is completed. Agree (4) Don t forget to save our work before we logoff. Respondent 8 Female (2) years (1) Strongly Agree (5)
