Content for your presentation

When you present your Excel, you need to...–Explain the meaning of your data (i.e. what the columns and the rows of your data represent?, what is your business?)

–Explain about the meaning of your Average, Max, and Min....(i.e. which products sell the most?)

A.Penjira (Mony) Kanthawongs 6

Using the AVERAGE, MAX, and MIN Functions

Excel includes pre written formulas c

alled functions t o help you compu te these statistics.

The values that yo u use with a functi

on are called arguments.

All functions begin wi th an equal sign and i

nclude the argument s in parentheses after

the function name.=AVERAGE(D3:D10)

Function Name is AVERAGE Argument is the range D3:D10

A.Penjira (Mony) Kanthawongs 7

The AVERAGE Function– ...t he statistical funct

ions ignore blank cells. Thus, in Excel, the ave. of three cells with values of 2, blank, and 4 is 3 or 2 4 2( + )/ , and not

2 or 2 0 4 3( + + )/ (Page 2.16 Orange B

)

The AVERAGE Function– sums the numbe

rs in the specifie d range and then

divides the sum by the number of

- non zero non-blank cells in therange.
