Practice Test

Take the Practice Test on Blackboard!!!!

• More than half of the questions will be formatted the same or similarly as the practice test

• Questions will have different numbers, but the same concepts

In This Review Session…

We will go over:

• Key terms in EXCEL

• Functions in EXCEL

• Practice Test Questions

Absolute, Mixed and Relative

For a formula being copied:

If the reference is: It changes to:

$A$1 (absolute column and absolute row)

$A$1 (the reference is absolute)

A$1 (relative column and absolute row)

C$1 (the reference is mixed)

$A1 (absolute column and relative row)

$A3 (the reference is mixed)

A1 (relative column and relative row)

C3 (the reference is relative)

The AVERAGE function

Syntax:

=AVERAGE(number1, [number2],...)

Arguments:

•number1 Required The first number, cell reference, or range for which you want the

average.•number2, ... Optional

Additional numbers, cell references or ranges for which you want the average, up to a maximum of 255.

The AVERAGE function

Description:

• Returns the average (arithmetic mean) of the arguments.

Remarks:• Arguments can either be numbers or names, ranges, or cell references

that contain numbers.

• Logical values and text representations of numbers that you type directly into the list of arguments are counted.

Errors:

Arguments that are error values or text that cannot be translated into numbers cause errors.

The AVERAGE function

The SUM function

Microsoft® Excel® Mathematical Functions

Syntax:

=SUM(number1, [number2], [number3], [number4], ...)

Arguments:

•number1 Required The first item that you want to add.

•number2, number3, number4, ... Optional The remaining items that you want to add, up to a total of 255

items.

The SUM function

Microsoft® Excel® Mathematical Functions

Description:

• Adds all the numbers that you specify as arguments.

Remarks:

• Each argument can be a range, a cell reference, an array, a constant, a formula, or the result from another function.

• If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, or text in the array or reference are ignored.

Errors:

If any arguments are error values, or if any arguments are text that cannot be translated into numbers, Excel displays an error.
