3. 1) Is depressed, blue 2) Is not relaxed, does not handle stress well 3) Can be tense

4. 4) Worries a lot 5) Is easily upset

5. Neuroticism Raw Score Add your answers –Your score can range between 5- 25 What does your score mean? Note: It is meaningless unless you know how others scored

7. Simple Frequency Distribution 1) Find the highest and lowest scores 2) Write in descending order all the numbers from 24 to 6

8. Simple Frequency Distribution 3) Start with the number in the upper-left corner, draw a line under it, and place a tally mark in the frequency distribution 4) Do this with all the data 5) Count the number a tally marks

10. Group Frequency Distribution Scores are grouped into equal-sized ranges called “class intervals” Usually want around 10 class intervals

25. Graphic Presentation of Data Basic parts of a graph X axis Y axis

26. Frequency Polygon Graphs quantitative data Neuroticism data

28. Frequency Polygon

34. Histogram Used to graph quantitative data Just like a frequency polygon, except it uses bars instead of lines

35. Histogram

41. Describing Distributions Bell-shaped distribution

42. Describing Distributions

44. Bar Graph Used to present frequencies of qualitative variables Looks like a histograph Each bar represents one category

45. Bar Graph

50. Line Graph A picture of a relationship between two variables Each point represents the value of the Y variable that goes with the corresponding X variable

51. Line Graph

53. Put subjects in order using your X axis

54. Line Graph

55. Marsha: N=22; H=2

56. Line Graph Greg: N=20; H=3

57. Line Graph Cindy: N=12; H=5

58. Line Graph Bobby: N=17; H=7

59. Line Graph Jan: N=15; H=8

60. Line Graph Peter: N=8; H=9

62. What is the meaning of the number 14 on the x-axis? What is the meaning of the number 14 on the y-axis? How many people had a score of 11? How about 23? What type of graph is this? What is its distribution?

63. What is the meaning of the number 20 on the y-axis? How many males and females are in the course? What type of graph is this? What scale does the x axis use? The y axis? Trick Question: What type of distribution is this?

64. What is the meaning of the number 10 on the x-axis? What is the meaning of the number 10 on the y-axis? What type of graph is this? Trick Question: What type of distribution is this?
