From its 2010 edition onward, Microsoft's Word program features integrated equation capability, including the availability of all descriptive mathematics symbols. These include the x-bar and mu, symbols used to indicate the sample mean and population mean in equations respectively. Obviously, these symbols aren't readily available on your keyboard, but by using the Equation and Symbol tools, you can easily add them.

## Sample Mean

#### Step

Launch Microsoft Word and open the desired document.

#### Step

Place the cursor where you need the x-bar symbol.

#### Step

Click the "Insert" tab and select the "Equation" tool.

#### Step

Click "Accent" from the Equation Design tool and select "Bar."

#### Step

Click beneath the bar symbol and type "x." This replaces the bar with the mean symbol, which you can then copy and paste as necessary throughout the rest of the document.

## Population Mean

#### Step

Place the cursor where you need the mu symbol.

#### Step

Click "Insert," followed by "Symbol."

#### Step

Click "More Symbols" and locate mu from the list. You can then easily copy and paste this symbol throughout the rest of your equations.
