  1. Remember? • Do you remember how to get to List 1 in your calculator? • How do you get the average and standard deviation in your calculator after typing information in? • Where is the variance located in your calculator? -Tests handed back next…

  2. Final ReviewDay 1

  3. Categorical or Quantitative? • Grade Point Average • Favorite Color • Height • Weight • Type of Pet You Own • Age • Q • C • Q • Q • C • Q

  4. Discrete or Continuous? • Age • Weight • Height • # of Pets • # of Video Games You Own • Distance You Live from School • D/C • C • C • D • D • C

  5. Frequency versus Proportion • What is the frequency of blondes? • Bl, Bl, Br, Red, Br • 2

  6. Frequency versus Proportion • What is the proportion of blondes? • Bl, Bl, Br, Red, Br • 0.4

  7. Frequency versus Proportion • What is the percentage of blondes? • Bl, Bl, Br, Red, Br • 40%

  8. Make a List… • What are all of the graphs we discussed in Chapter 2?

  9. Make a List… • Pie Chart, Bar Graph, Stem and Leaf Plot, Dot Plot, Histogram, Time Plot, Pareto Chart

  10. Pareto Chart

  11. Create a Stem & Leaf Plot • 85, 72, 75, 90, 85, 85, 88, 93, 95, 90 7 25 8 5558 9 0035

  12. What is the range, mode, median, mean?

  13. What is the range, mode, median, mean?

  14. Time Series Plot

  15. Mean, Median, Standard Deviation, Variance • 85, 72, 75, 90, 85, 85

  16. Mean, Median, Standard Deviation, Variance • 88, 93, 95, 90, 65, 45, 58, 62, 72, 93, 95

  17. Mean, Median, Standard Deviation, Variance • 3.2, 3.5, 2.5, 4.0, 1.7, 2.5, 3.8, 3.6, 3.6

  18. Empirical Rule • Females between 25 and 34 years of age have a bell-shaped distribution for height, with a mean of 65 inches and standard deviation of 3.5 inches • Give an interval within which 68% of the data falls. From 61.5 to 68.5

  19. Empirical Rule • Females between 25 and 34 years of age have a bell-shaped distribution for height, with a mean of 65 inches and standard deviation of 3.5 inches • Give an interval within which 95% of the data falls. From 58.0 to 72.0

  20. Empirical Rule • Females between 25 and 34 years of age have a bell-shaped distribution for height, with a mean of 65 inches and standard deviation of 3.5 inches • Give an interval within which 99.7% of the data falls. From 54.5 to 75.5

  21. Empirical Rule • Which scenario creates a graph that is MORE spread out? • 1) μ=4.5, σ=1.9 • 2) μ=7.2, σ=3.4 #2 – bigger standard deviation

  22. Box and Whisker Plots

  23. Create a Box and Whisker Plot • 85, 72, 75, 90, 85, 85

  24. Create a Box and Whisker Plot • 88, 93, 95, 90, 65, 45, 58, 62, 72, 93, 95

  25. Create a Box and Whisker Plot • 3.2, 3.5, 2.5, 4.0, 1.7, 2.5, 3.8, 3.6, 3.6

  26. Interquartile Range • Minimum = 33,100 • Q1 = 39,250 • Median = 42,700 • Q3 = 48,850 • Maximum = 61,800 • Q3 – Q1 = 9,600

  27. Z-score • The mean is 8.20 and the standard deviation is 4.56. Find the z-score associated with the value of 1. • What does this mean?

  28. Z-score • The mean is 8.20 and the standard deviation is 4.56. Find the z-score associated with the value of 11.3. • What does this mean?

  29. Z-score • The mean is 8.20 and the standard deviation is 4.56. Find the z-score associated with the value of 8.20. • What does this mean?

  30. Learning Objective 2:Class Exercise There are 7 students in a class who are either freshman, sophomores, juniors, or seniors. The number of students in this class who are juniors is _____. 3

  31. What is the skew?

  32. Unimodal or bimodal?

  33. Time for our study guide!! • I will post answers to my web site some time tomorrow after you have had a chance to work through it.
