To save your spreadsheet now or at any time, select Save or Saved As ... from under the File Menu on the top menu bar. Give your spreadsheet a distinctive name. As in any other Macintosh application, you must make sure to save your spreadsheet to some location. When you are certain that you are saving to where ever it is you want it to go, click Save. Let us say we are interested in examining the relationship between body weight and gender. That is, do males and females differ in their body weights? Likewise, we might also be interested in the difference in height between males and females. To analyze weight and height as a function of gender, go to Graphs on the menu bar and select Bar. Now, select "Clustered" and "Summaries of separate variables" and click on Define. A window entitled, Define Clustered Bar will appear. Because we are interested in weight and height, we want to assign "weight" and "height" as variables to the Bars Represent box on the right side of the window. You assign these variables by highlighting them in the left side of the box at the left and use the arrow to move them into the box on the right. Move Body Weight, LB into the box. When moving "height" into the box, the box may automatically enlarge. Next, highlight Gender and move it into the Category Axis window using the arrow. There are many other options to choose from but we will do this much for now. Click OK. Clicking OK will result an untitled view of a bar chart relating weight and height. To change the look of the bar graph you can alter the shape, configuration, and other features. For example, to change the Y-axis, double click in the middle of the graph. A new graph labeled Chart will appear. Double click on the numbers of the Y-axis and make any appropriate changes to the Y-axis with the box that pops up. For example, change the number of major division increments. Click on Graphs on the top menu and scroll down to Error Bar and click. In our case, we will use "Clustered" and "Summaries of Separate Variables" Click Define. Move bodywt and height into the variables box and Gender into the Category Axis box. Click OK. The new graph is a picture of the mean of each group with error bars encompassing 95% of the scores above and below the mean. Lets determine the mean weight and height for this group of subjects. To do this go to the main tool bar and select Analyze, then Descriptive Statistics, then descriptives. Move body weight and height into the variables box and click OK. You should see that the mean weight and height are 131 and 62.7 respectively.
