GATHERING DATA  
 
Students will be able to:  
• Form questions that can be answered by data  
• Verify frequency distributions, tables, and graphs using data  
• Choose appropriate tables and graph to be consistent with the nature of the data  
• Use table and graphs to determine variation between groups.  
• Relate the data analysis to the content of the question posed.  
 
Examples  
1. Given the data below, organize it in a stem-and-leaf plot, frequency table or line plot.  
 
Scores in a local golf tournament: 81, 82, 76,79, 68,70,80, 67,76,75,82, 67,  
77 ,67 ,73, 72 ,72, 74, 76, 83  
Sample responses:

Key: 6|7 = 67  
or

scores  
 
Twenty players participated in the golf  
tournament. The average (mean) score was  
74.85 or about 75. This is 3 point above par.  
As the histogram shows, seven players scored at  
par or below, seven slightly above par (73-78),  
and the remaining six were well above par. The  
median score was 75.5 which means that half of  
the players scored below 75.5 and half scored  
above 75.5. The highest score was 83 and the  
lowest was 67 for a range of 16 points. This  
wide of a range suggests that there was much  
variation among the players’ performances in  
this tournament.
