CONSTRUCTING RELATIVE CONSTRUCTING RELATIVE FREQUENCY DISTRIBUTIONFREQUENCY DISTRIBUTION

For For RELATIVE FREQUENCY RELATIVE FREQUENCY DISTRIBUTIONDISTRIBUTION of grouped data, of grouped data, we can use Excel by using the we can use Excel by using the ∑∑ symbol from the toolbar to take the symbol from the toolbar to take the sum the total of the data in the sum the total of the data in the frequency column, relative frequency column, relative frequency column and % frequency frequency column and % frequency column.column.

The screen for Excel looks like this –The screen for Excel looks like this –

this box is called a cell and the cell address is A1.

this box has the cell address B16; meaning it is located at the intersection of column B and row 16

this highlighted part is called a column

this highlighted part is called a row

1. Make sure that you have already 1. Make sure that you have already entered the manually computed entered the manually computed individual data to their proper cells and individual data to their proper cells and columns.columns.

2. 2. To get the totals for each column, To get the totals for each column, highlight (with the white cross appearing, click highlight (with the white cross appearing, click & drag the mouse) all the data on the & drag the mouse) all the data on the frequency column (or relative frequency and % frequency column (or relative frequency and %

frequency column).frequency column).

3. After releasing the mouse, click the ∑ symbol from the toolbar

3. It will automatically input the answer to the cell just below the last cell in the frequency column (or in their respective columns). You can do the same for the other columns (that is, after the values are entered or computed).

4. For the relative frequency and 4. For the relative frequency and % frequency, use the calculator % frequency, use the calculator then input the results in their then input the results in their proper cells manually, that is if proper cells manually, that is if you really don’t know how to you really don’t know how to utilize Excel. But, try to do the utilize Excel. But, try to do the procedure below to find out how procedure below to find out how easy to do these computations easy to do these computations with Excel. No need for a with Excel. No need for a calculator.calculator.

5. Try deleting first the entries in 5. Try deleting first the entries in the last 2 columns to see how the last 2 columns to see how it works.it works.

To compute for relative frequency (rf) To compute for relative frequency (rf) using Excelusing Excel, all you need to do is to , all you need to do is to set the formula for the first set the formula for the first computation. Noting that that the computation. Noting that that the first rf = 3/40, first rf = 3/40, click on cell C2, click on cell C2, then, type =B2/$B$9 and press the then, type =B2/$B$9 and press the enter keyenter key..

Note that B2 is the cell address of the data 2 Note that B2 is the cell address of the data 2 and B9 is the cell address of 40. For the and B9 is the cell address of 40. For the succeeding data, the formula is the same succeeding data, the formula is the same but B2 changes to B3, B4, etc while B9 is but B2 changes to B3, B4, etc while B9 is fixed; thus, the $ signs are used to fixed; thus, the $ signs are used to indicate that 40 is a fixed value in the indicate that 40 is a fixed value in the

formula, B2/$B$9.formula, B2/$B$9.

7. Since the same formula applies 7. Since the same formula applies for the entire column, just copy the for the entire column, just copy the formula by using the copy & paste formula by using the copy & paste icons or dragging the mouse icons or dragging the mouse downwards with the black cross at downwards with the black cross at the corner of the cell (before the corner of the cell (before dragging).dragging).

+

The black cross appears at the right corner

If the values are not presented with two (2) If the values are not presented with two (2) decimal places, you may format the data decimal places, you may format the data by by highlighting the columnhighlighting the column, , then click on then click on

the format icon, then select cellsthe format icon, then select cells

Select Number then type 2 for decimal places and click ok

9. For the % frequency (%f), the values 9. For the % frequency (%f), the values are equal to the rf column but they are equal to the rf column but they should only be expressed in % form. To do should only be expressed in % form. To do this with Excel, this with Excel, just type =C2 on cell D2, just type =C2 on cell D2, press enter and copy for the entire press enter and copy for the entire

column as in step 7column as in step 7..

ToTo express in % form with 2 express in % form with 2 decimal places, with the data still decimal places, with the data still highlighted, highlighted, select Format then select Format then Percentage then type 2 for Percentage then type 2 for decimal places and click ok.decimal places and click ok.

10. Compute for the totals as in 10. Compute for the totals as in steps 2 & 3. The final output would steps 2 & 3. The final output would look like this.look like this.

11. You can copy your output and paste into your file in MSWord. However, after using the paste icon, one can no longer manipulate or change the calculations. Another way is discussed below

The worksheets shown in the previous The worksheets shown in the previous discussion were created when one is discussion were created when one is using the Excel Software.using the Excel Software.

Actually, the table was constructed just Actually, the table was constructed just the same using Excel but in the the same using Excel but in the MSWord environment; that is, MSWord environment; that is, importing Excel features into the importing Excel features into the MSWord screen.MSWord screen.

Let us do it! First, open a new file in MSWord. Type in Let us do it! First, open a new file in MSWord. Type in some headings, then, create the table by double-some headings, then, create the table by double-clicking on the clicking on the Excel iconExcel icon. Just highlight on the cells . Just highlight on the cells shown by simply dragging the mouse .shown by simply dragging the mouse .

Just after releasing the mouse, the table in the Excel Just after releasing the mouse, the table in the Excel environment is constructed. The table can be expanded by environment is constructed. The table can be expanded by simply dragging the mouse at the lowest right corner of the simply dragging the mouse at the lowest right corner of the table.table.

Note that when you click Note that when you click outside the table, you are in outside the table, you are in MS Word EnvironmentMS Word Environment

To work on the table, just To work on the table, just double click inside the double click inside the table. Note that you are in table. Note that you are in MS Excel Environment.MS Excel Environment.

The frequency distribution table can now be The frequency distribution table can now be constructed using Excel by following the constructed using Excel by following the previous discussion.previous discussion.

That’s all folks! Good day!That’s all folks! Good day!
