SPSS Summary Statistics
Our first topic of statistical analysis is the method we use to derive tables of summary
statistics from SPSS for Windows. For this purpose we choose the data obtained for
Questions 3 in the questionnaire we used for the previous section, which is the
likelihood of the respondents buying a packet of Woolworth dog biscuit at $15 per
packet. The answers are given in a scale from 0, which means that the respondent will
definitely not buy it, to 10, which means that the respondents will definitely buy it.
To obtain our summary statistics using Frequencies analysis, from the menus choose:
Analyze
Descriptive Statistics
Frequencies...
The following dialogue box appears. On the left hand side, you will see a list of all of
the variables that you have defined. We select 'likelihood of buying':
Now click on the right arrow near the middle of the dialogue box. You will see that
the variables have now been taken to the Variables list on the right hand side of the
dialogue box.

Now click on the Statistics button. A dialogue box called "Frequency: Statistics"
comes up in which you can select quite a large number of calculations of summary
statistics that you can request your computer to do on your data. Here we have
selected the mean, standard deviation, median, minimum, maximum and mode etc..
Click on the continue button to return to the original dialogue box.
Another button that you can click on is the Charts button, which draws up a dialogue
box named "Frequencies: Chart." Here you can ask the computer to draw from you
data a variety of graphs. Here we have selected Pie charts.
