  8. Imagine your colleague asked you for your advice on creating a function in Excel, would you suggest the old-fashioned method (page 24) or the (fx) command method (page 25)? Explain the reasoning behind your suggestion. (3 pts)
  • Old-fasioned way: Enter the function in the cell where you want the results to appear, Type =AVERAGE(B2:B11) in Cell B12. (Using upper case or "capital" letters is the standard way to spell a function, but it will work with lower case letters, too.) Press the Enter key, and presto: As you see in Figure 2.7, the sum shows up in Cell B12, and in the formula bar, you can see the structure of the function.
  • (fx) command method: Type =AVERAGE(B2:B11) in Cell B12. (Using upper case or "capital" letters is the standard way to spell a function, but it will work with lower case letters, too.) Press the Enter key, and presto: As you see in Figure 2.7, the sum shows up in Cell B12, and in the formula bar, you can see the structure of the function.Now you can do one of two things: Form a brief description of what you want to do, such as average, and click the OK button; or Find the function you want in the list of functions and double-click on it. Click OK, and you will see the same result as you saw in Figure 2.7. We entered the function using the Insert Function command instead of by typing its name, but we got the same result.
