Transcript

  • 1. Math Dictionary Chapter 12
    By: Derek Marsh and Tyler Henderson
  • 2. Range, Median, Mean, Mode
    Range- The difference between the highest and the lowest #s in the data.
    Median- The middle # when the data are put in order
    Mean- sum of the #s divided how many #s there are
    Mode- the # that appears the most often
  • 3. Stem and leaf plot
    A way to display data by putting it in order!
  • 4. Lower and Upper quartiles
    Lower quartile- median of the first half of the data
    Upper quartile- median of the second half of the data
  • 5. Box-and-whisker plot
    Used to organize and display data by breaking into quarters
  • 6. Lower and Upper extreme
    Lower extreme- lowest # in the data
    Upper extreme- highest # in the data
  • 7. Circle and line graphs
    Circle graph- breaks data into parts of a whole
    Line graph- displays data over time
  • 8. Tree Diagram
    A diagram used to show all the possible outcomes/ combinations
  • 9. Fundamental Counting Principle
    If one event can occur in m ways and then the second event can occur in n ways. The ways that the two events can occur together is m*n
  • 10. Complementary
    When one or the other event has to happen probabilities will add up to one
  • 11. Unfavorable outcome
    The outcome you don’t want to happen
  • 12. Odds
    The ratio of favorable outcomes to unfavorable outcomes
  • 13. Probability
    Number of favorable outcomes over the total number of outcomes.
  • 14. Independent and Dependent Events
    Independent: The first event does not affect the second event.
    Dependent: The first event does have an affect on the second event.
  • 15. Stem and leaf plot
    0 1 8 8 8 8
    1 0 0 1 2 2 3 3 9
    Mean:10.2
    Median:10
    Mode: 8
    Range: 18
  • 16. Fundamental counting principle
    8 x 4 x 3= 96
    The probability is 1/96
