Mean- Also known as the average. The mean is found by adding up all of the given data and dividing by the number of data entries. Median- The median is the middle number. First you arrange the numbers in order from lowest to highest, then you find the middle number by crossing off the numbers until you reach the middle. Example: - use the above data to find the median: 66 74 75 78 82 89\ - as you can see we have two numbers, there is no middle number. What do we do? It is simple; we take the two middle numbers and find the average 75 + 78 = 153 153 / 2 = 76.5 Hence, the middle number is 76.5. Mode- -- this is the number that occurs most often. Range-The Range is the difference between the lowest and highest values.
Cluster-When data seems to be "gathered" around a particular value. Gap-anemptyspacelocated graph in a set of numbers Outlier-A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.
Perimeter- the distance around a polygon. You add up all the sides. Triangle - polygon that has 3 sides Quadrilateral - has 4 sides and includes rectangles, squares, kites, rhombus, and parallelograms Pentagon- a polygon that has 5 sides Hexagon- polygon that has 6 sides Septagon - polygon that has 7 sides Octagon- polygon that has 8 sides Nonagon- polygon that has 9 sides Decagon - polygon that has 10 sides
