The document introduces Excel's statistical applications, emphasizing its importance for university courses, especially in finance. It covers various Excel functions such as SUM, COUNT, AVERAGE, logical functions, and how to perform statistical analysis using data analysis and pivot tables. Additionally, it provides resources for practice and encourages students to learn Excel for future career opportunities.

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.xlsxhttp://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

13. Pivot tableBasic Functions

14. The SUM function…The sum function is one of the most commonly used functions= SUM (cell1, cell2, cell3, etc) or = SUM (range1, range2, range 3, etc)= SUM (A1,A2,A3,A4)  will add the numbers in cell A1, A2, A3 and A4

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

17. You can also sum for a multiple ranges, so if you have one set of data in one area and another The COUNT function…The count function allows you to count either the amount of number cells of the number of non blank cells in a range.= COUNT (range1, range2, etc) or = COUNTA (range1, range2, etc)= COUNT (A1:A25)  will count the amount of numbers from cell A1 to A25

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

21. Using a combination of sum and count you can create an average by dividing the sum by the countThe AVERAGE function…The average function is used to average a set of numbers= AVERAGE (cell1, cell2, etc) or = AVERAGE (range1, range2, etc)= AVERAGE (A1,B1,C1)  will find the averages of the cells A1, B1 and C!

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

24. Average is useful, however you can’t use logical functions and hence the sum and count functions are usually more useful for composing an averageLogical Functions

25. The IF function…You use the IF function is you want a cell to display certain text or numbers given a certain function = IF (logical test, value if true [put text in “__”, value if false)= IF (A1>0.5, “Pass”, “Fail”)  Will check cell A1 and if the value is more than 0.5 the cell where you wrote the formula will show pass, otherwise it will show fail.

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.
