# How to Make an X-Bar Symbol in Word

Word 2013 creates x-bar symbols as regular text using symbols or Alt-Codes, but you can also include x-bar in complicated formulas using the Equation Editor.

The statistical symbol x-bar represents a sample mean in contrast to the Greek symbol *mu*, which looks similar to a u and represents the population mean. To include the x-bar symbol in regular text, combine diacritical marks or use Alt-Codes for the quickest solution, but within equations, use accents to construct the symbol.

### Using Alt-Codes

**Alt-Codes offer the quickest method of entering the x-bar symbol**, because you don't need to open additional dialogs, and the effect is identical to using the Symbols dialog to add the horizontal bar. Word 2013 contains two appropriate Alt codes: 0772 and the slightly longer bar 0773.

#### Step 1

Type an **x** where you want the x-bar symbol to appear, and then hold down the **Alt** key.

#### Step 2

Type **0772** or **0773** using your numeric keypad. When you release the Alt key, the bar appears above the x.

#### Tip

Alt-Codes work only when entering the appropriate number using a numeric keypad. **If you don't have a keypad, use the Symbol dialog to create the x-bar symbol**. Keep in mind that smaller laptops often have keypads combined with regular keys; hold the **Function** key to use these keypads.

### Using the Symbol Dialog

#### Step 1

Type an **x** where you want the x-bar symbol to appear.

#### Step 2

Click the **Insert** tab, select **Symbol** from the Symbols group and choose **More Symbols**.

#### Step 3

Double-click the **0304** or **0305** character, listed under Combining Diacritical Marks. Adding these marks is identical to using the 0772 or 0773 Alt-Codes, respectively.

#### Tip

If you have trouble finding the symbol, enter **0304** or **0305** in the Character Code box to quickly find and select the appropriate mark.

### Using the Equation Editor

#### Step 1

Click the **Insert** tab and select **Equation** from the Symbols group.

#### Step 2

Select the **Design** tab, click the **Accent** drop-down menu from the Structures group and choose the **Bar** symbol.

#### Step 3

Click the empty square with the bar on top and type an **x**. When you click outside the equation, the x-bar symbol displays normally.
