Statistics: The branch of mathematics  that deals with collecting, organizing,  and analyzing or interpreting data. Data: Numerical facts or numerical  information. Stem-and-Leaf Plots: A convenient  method to display every piece of data  by showing the digits of each number.
In a stem-and leaf plot, the greatest  common place value of the data is used  to form stems.  The numbers in the next greatest place- value position are then used to form the  leaves.

28 4 Stem Leaf Leaf: The last digit on the right of the  number. Stem: The digit or digits that remain when  the leaf is dropped. Look at the number 284 The leaf is the last digit formed: the number 4. The stem is the remaining digits when the leaf is dropped: the number 28. The stem with the leaf forms the number 284. = 284
Here are the scores from two periods of math  class. Students took the same test. Period 1: 77 79 85 58 97 94 82 81 75 63 60 92 75  98 83 58 72 57 70 81  Period 2: 57 60 88 85 79 70 65 98 97 59 58 65 62  77 77 75 73 69 82 81
