PROBLEM:  Can you learn how to estimate?

PREDICTION: 

MATERIALS:  3 containers filled with items given to you by your instructor

PROCEDURE:
For each container:  (1) estimate the number of items that are in the container and record, and (2) count the actual number of items it took to fill the container and record.  Complete one container at a time.  Record the results below.
 

ITEM

1

2

3

ESTIMATION

       

ACTUAL NUMBER

      

Plot the above data as a bar graph on the chart below as accurately as possible.  The difference between the actual number and the number estimated is the margin of error (how far off the estimation was).  Color the margin of error a separate color.  Make the x axis estimation/actual number, and y axis the number of items.
 

                                    
                                   
                                    
                                   
                                   
                                   
                                   
                                   

CONCLUSIONS:  Summarize your findings.  Discuss your margin of error for each container.  Were you close?
