Statistics Measures of Variation Unit Plan
... In this unit we will look at Five Basic Measures of Variation: Range, Deviation, Sum of Squares, Variance and Standard Deviation. We already know how to find range from when we made Frequency Tables: It is the maximum minus the minimum. The next Measure of Variation we will look at is deviation. Eac ...

Mean, Median and Mode
... Mode: is the data item that occurs most often. There can be one mode, multiple modes, or no mode. You can say how many modes there are too! What about our previous data set? 2, 3, 4, 5, 8, 8, and 12 8 is a mode for these data items. ...

Probability Review
... Addition Rule: P(A B) = P(A) + P(B) - P(A B) This formula is given on the AP Test. (p. 304) Mutually exclusive or Disjoint means the two events have nothing in common. If two events are mutually exclusive, P(A B) = 0 (p. 305 with Venn diagrams) Conditional probability. Let A and B be two event ...
