    I have scores on a 100-point final exam from one class provided by OpenIntro.org Can you look at them in Table \(\PageIndex{1}\) and quickly tell how the class did?  

    Table \(\PageIndex{1}\)- Final Exam Scores
    79 83 66 81
    83 72 89 88
    57 74 78 69
    82 73 81 77
    94 71 78 79

    Even if you could get a general idea of how these 20 students did on the final exam, this is not the best way to understand data sets.  And just imagine if the class had 40 or 100 students in it!  

    When you deal with data, you may have so many numbers to you that you will be overwhelmed by them. That is why we need ways to describe the data in a more manageable fashion.  

    We'll start that in this chapter on charts, then describe whole sets of data in only a few important numbers in the following chapter.
