33. $100 Question What is an outlier?

34. $100 Answer Data that stands out compared to the overall pattern of the entire data.

35. $200 Question Given the data which one is the outlier: 2, 4, 22, 6, 1, 4, 1, 5, 7, 4

36. $200 Answer 22

40. $400 Answer Skewed to the left

41. $500 Question Looking at a Box plot (box and whisker) what do you look for to help you describe the pattern?

42. $500 Answer Look at the whiskers. If they are: Equal = symmetrical Right longer = Right skewed Left Longer = Left Skewed

43. $100 Question What is Standard Deviation?

44. $100 Answer It is the average distance away from the mean. OR A measure of spread

45. $200 Question When finding standard deviation what do you do after you’ve ordered your data and found the mean?

46. $200 Answer Find the distance between the scores and the mean

47. $300 Question What are the next two steps after finding:

48. $300 Answer 1.Total all of those squared differences 2. Average these distances by dividing by (n-1) one less then the total.

49. $400 Question Once you have variance how do you find standard deviation?
