Slides for the Introduction to Excel - Application to Statistics workshop for UNSW Business Society Core Skills Workshops series Semester 1, 2011

1. Week 10: Introduction to Excel – Statistical Application

2. Why excel? Why should I care about excel? It helps with your university courses, especially if you’re doing finance where you’ll encounter it in 1613, 2624, Applied Corporate Finance, Options, Applied Corporate Finance etc. But I have an awesome friend who knows excel and will do it all for me! Well, that friend won’t be there forever, especially when you get an internship or a graduate job where knowing how to use excel will help you adapt quicker and give you a better chance at doing well. I don’t plan to work in commerce! Well then… WHAT ON EARTH ARE YOU DOING HERE?!?! Now that we have that sorted, please go to the link below to download the excel spreadsheet with exercises and data for practice. www.unswbsoc.com/media/Introduction to Excel - Application to Statistics.xlsx http://myendlesssoliloquy.files.wordpress.com/2011/05/introduction-to-excel-application-to-statistics1.xlsx

4. Sum

5. Count

6. Average

7. Logical statements

8. IF statements

9. Sumif

10. Countif

11. Statistical methods

12. Data analysis

15. = SUM (A1:A4)  will add the numbers in cells A1 to A4

16. You can also simple just add cells such as = D1 + C2 + B4

18. = COUNTA (A1:A25)  will count the amount of non-blank cells from A1 to A25 (use this to count text)

19. You use COUNT for numbers and COUNTA for text

20. Just like the sum function, you can count in multiple ranges

22. = AVERAGE (A1:A25)  will find the average of the calls from A1 to A25

23. You can use multiple cells or ranges in the average function

26. You can also expand the logical test with functions like AND, OR and NOT

27. = IF (AND(A1>0.5,A1<0.75,”Come see me”, “”)  Will check cell A1 and if the value is larger than 0.5, but less than 0.75. If so it will display “Come see me”, otherwise it will just be left blank.

28. You can also imbed multiple IF functions up to 13 in total. Usually people will embed the extra IF function into the value if false part of the function

29. = IF (A1>0.5, IF (A1<0.75, “Come see me”, ”Good”),””)  Will do the same as above, but you should notice that this is the same as the function above, but if A1 is larger than 0.5 but not less than 0.75 (ie. Larger than 0.75) then it will display good instead of come see me

31. You can use multiple criteria in a sumif by using the AND and/or OR functions

32. The criteria range can be any row or column parallel to the sum range

35. This is great when you just want a summary of the data

36. If you want to separate the statistics for the information, simply filter and sort the information into the sections you need and then simply perform statistical analysis on those individual sectionsSort Filter

37. First you need to turn on the add-in by clicking on the first and then excel options

38. Go to add-in and then choose excel add-ins then press go

39. Choose analysis tool pack in the window that opens and then click ok

40. Now that you have the addin you can start using data analysis in the data tab

41. Select the data tab and then data analysis and descriptive statistics

42. Fill in the input range, where the statistics will be output and whether you want summary statistics

43. And now you can see the results in a table with the essential statistical measurements

44. Statistical MethodsPivot Table

45. Alternatively you can use pivot tables in order to sort and analyze the data

46. Highlight the data and then go to data and click on PivotTable and fill out the range and the output

47. Now you have a PivotTable which you can play with by pulling labels into the grid

48. Here is an example, the bottom left box puts headings on the y-axis, bottom right on the x-axis

49. You can also change what data is shown by clicking on each data label

50. You can select a range of ways the data is shown, by count, average, max, min, etc.
