**Frequency Distribution**

A Frequency Distribution is a summary of how often each value occurs by grouping values together.

*For example, you have data for class sections with the number of students in each section.*

Excel : Frequency Distribution |

- With
**COUNTIFS**Function - With
**FREQUENCY**Function

**Calculate Frequency Distribution in Excel**

1. Enter the above data in cells

**B3:C15.**The first row of table has headers.

The same data entered into a sheet in excel appears as follows :

2. Select the desired class intervals

3. Create a table with the columns - Class intervals, Lower limit, Upper limit and Frequency.

**How to calculate lower and upper limits using excel formula -**Suppose class interval column starts from cell E5 (excluding header).

**Lower limit -**

Enter the following formula in cell F5 and paste it down till the last row of the table.

=MID(E5,1,FIND("-",E5,1)-1)

**Upper limit -**

**Enter the following formula in cell G5 and paste it down till the last row of the table.**

=MID(E5,FIND("-",E5,1)+1,2)

**Frequency Distribution with COUNTIFS Function -**

To calculate the last column of the above table, enter the following formula in cell H5 and paste it down till the last row of the table

=COUNTIFS($C$4:$C$15,">="&F5,$C$4:$C$15,"<="&G5)

**Frequency Distribution with FREQUENCY Function**

Create a table with the columns - Class Intervals, Upper Limit and Number of Sections

Upper Limit can be calculated with the formula below in cell F5 -

--MID(E5,FIND("-",E5,1)+1,2)

**Paste the formula down till cell F9. Make sure you enter double minus (--) before MID function.**In the next step, select range

**G5:G9**and then enter

**FREQUENCY**Function

=FREQUENCY(C4:C15, F5:F9)

*F5:F9 refers to bins of Upper Limit.**Press*

**CTRL SHIFT ENTER**to submit the above**FREQUENCY**formula as it's an array formula. If it is entered correctly, you would see formula wrapped in curly braces { }**Histogram**

We can prepare histogram using frequency table.

**Steps:**

1. Highlight the values in

**class intervals**column**(Column E)**and**Frequency**column (**column H)**of the frequency distribution table.*(Holding down Ctrl key while highlighting two ranges)*
2. Click on the

**Insert**tab and select**2-D Clustered Column**.
3. Remove

**Series1 -**Select Series1 and Press Delete**Adding axis title**

1. Click on the chart.

2. Click the

**Layout**tab under**Chart Tools**.
3. Click

**Axis Titles**in the**Labels**group.
4. Select

2. Click the

**Layout**tab under**Chart Tools**.
3. On the

**Layout**tab of the ribbon, click on the**Axes**button.
4. Select

**Primary Vertical Axis**>> Select**More Vertical Axis**Options.
5. In the

6. For

7. Press

**Axis Options**section, for**Minimum**, select**Fixed**and enter the lowest number you want on your Y-axis. In this chart, i used**0.**6. For

**Maximum**, select**Fixed**, and type the number where you want the Y-axis to end. In this chart, i used**5**.7. Press

**Close**
...or you can just use the array formula frequency
