  2. Which measure of center would change the most if the outlier was removed from this data set: 86, 84, 80, 48, 90, 75, 88

  3. Remember… measures of center are the MMMR (mean, median, mode, range)Range

  4. Which measure of center would change the most if the outlier was removed from this data set: 13, 28, 11, 14, 9, 10, 14

  5. Remember… measures of center are the MMMR (mean, median, mode, range)Range

  6. Major League Baseball tracks a variety of statistics, including individual home runs in a season. The table shows the baseball players with the greatest number of home runs in 2007.

  7. Find the Mean, Median, and Mode.

  8. MEAN: 41.8 (REPEATING)Median: 40Mode: 35

  9. Find the measures of variability of the data in the first problem!(think box and Whisker!)

  10. Range: 20Median: 40q1: 35q3: 48.5Interquartile Range (IR): 13.5

  11. Find the mean absolute deviation (MAD) of the data from problem 2. Round to the nearest tenth!

  12. MAD = 6.5

  13. The table shows the ages of actors who starred in successful tv shows.

  14. Find the measures of Center of the data.

  15. Mean: 26.5Median: 25.5Mode: 24 & 29

  16. Find the measures of Variability and any outliers.

  17. Range: 42Median: 25.5Q1: 21.5q3: 29.5IR: 8Outliers: 8, 44, 50

  18. Find the Mean absolute deviation (MAD).

  19. MAD: 7.2

  20. What are the Mean, median and mode of the data. Number of cell phones returned: 20 15 24 37 55 1 39 40 3 35 28 0

  21. Mean: 24.75median: 26Mode: no mode

  22. What are the Mean, median and mode of the data. Number of tablets returned to store 18 22 17 23 16 14 22 17 22 18

  23. Mean: 18.9median: 18Mode: 22

  24. What are the mean and mean absolute deviation (MAD) for the set of Data. 7, 8, 4, 5, 8, 3, 5, 6

  25. Mean: 5.75 MAD: 1.5

  26. What are the mean and mean absolute deviation (MAD) for the set of Data. 3, 8, 2, 7, 3, 6, 1, 0, 2, 3

  27. Mean: 3.5 MAD: 2.1

  28. What is the mean absolute deviation (MAD) for the set of Data. Spanish club attendance 14 21 17 26 13 20

  29. MAD: 3.8

  30. A jar contains 1 blue marble, 11 yellow marbles, and 8 green marbles. What is the probability of randomly choosing a blue marble, replacing it, and then choosing a blue marble again?

  31. 1/400(think, 1/20 on the first try, multiply by probability of second try which is also 1/20) 1/20 ∙ 1/20 = 1/400)

  32. John loads a washing machine, he needs to choose a load setting of large, delicate or small; a water temperature setting of hot, warm or cold; and a regular rinse cycle or an extra rinse cycle. What is the possible number of outcomes in this situation?

  33. 18 choices

  34. Jesse starts a dishwasher, he needs to choose a dish setting of either pots and pans or regular; a drying temperature of either air dry or heat; and a regular or extra rinse cycle. What Is the possible number of outcomes?

  35. 8 Outcomes

  36. a. What do you know about the minimum, maximum, quartiles, range and median of the data? PhilAdelphiaChicago b. Make an inference about the plots. What statements can you make based on the data? Look at the box plots. They represent the number of times teenagers look at their phone in an hour. One plot represents teens in Philadelphia, the other represents teens in Chicago.

  37. a. List or make a table with all your statisticsb. This is where you need words!!! (try to be specific)Example: The median shows that teens in Philadelphia look at their phones 16 times an hour while Chicago teens check less often at 13 times an hour.
