What is a distribution (Update - 2.0)

1. What is a Distribution?

2. We will illustrate what a distribution is with a data set that describes the hours students’ study

3. Here is the data set:

4. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5

5. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Data

6. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Data Set

7. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 From this data set we will create a distribution:

8. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5

9. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 The X Axis, will be the number of hours of study

10. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5

11. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5

12. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5 The Y Axis, indicates the number of times the same number occurs

18. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5 Number of Occurrences

19. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5 NumberofOccurrences

20. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5 NumberofOccurrences

21. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5 NumberofOccurrences 1 2 3

34. Student Hours of Study Bart 1 Basheba 2 Bella 2 Bob 3 Boston 3 Bunter 3 Buxby 4 Bybee 4 Bwinda 5 Hours of Study 1 2 3 4 5 NumberofOccurrences 1 2 3 This is a distribution

37. One way to represent a distribution like this: Is like this:

38. One way to represent a distribution like this: Is like this:

39. One way to represent a distribution like this: Is like this: Normal distributions have the majority of the data in the middle

40. One way to represent a distribution like this: Is like this: Normal distributions have the majority of the data in the middle

41. One way to represent a distribution like this: Is like this: With decreasing but equal amounts toward the tails

42. One way to represent a distribution like this: Is like this: With decreasing but equal amounts toward the tails With decreasing but equal amounts toward the tails

43. Distributions can take other forms as well:

44. Distributions can take other forms as well: Hours of Study 1 2 3 4 #ofOccurrences 7

48. Distributions can take other forms as well: Skewed RIGHT

49. Distributions can take other forms as well: Hours of Study 5 6 72 #ofOccurrences 1

50. Distributions can take other forms as well: Skewed to the LEFT

53. Distributions can take other forms as well: Or NON-NORMAL
