|   Now that the data is entered and 
    saved, let’s go to the Analyze menu and process it. Click Analyze, click 
    Compare means and then Click Paired-Samples T Test.    
     This will appear. You will see your 
    variables in the box on the left. Your goal is to get both variables over to 
    the right.    
   Click on each of the two variable 
    names to highlight them. Make sure both variables are highlighted at the 
    same time. You will see each variable name in the “Current Selections” box 
    in the bottom left. That’s a good sign. When you are finished highlighting 
    the variables, move them both over by clicking the arrow button.     
 
     After 
    you move the variables    You will see that both variable 
    names appear in the “Paired Variables” window on the right. You will see a 
    little dash between the variables and the variables. When you are finished, 
    click the OK button and wait a few seconds for processing.    
     Your results will appear in an 
    output file that is something separate from the data file. It will probably 
    look something like this.      
     Make sure you save your results to a 
    meaningful place and with a meaningful name. You can do this by clicking 
    File and then Save or Save As. I will choose the name “Effect of Caffeine on 
    Number of Hours of Sleep Output.spo” This name will help me access the file 
    in the future.
