  1. CONSTRUCTING RELATIVE & CUMULATIVE FREQUENCY DISTRIBUTIONS using EXCEL & WORD

  2. CONSTRUCTING RELATIVE FREQUENCY DISTRIBUTION For RELATIVE FREQUENCY DISTRIBUTION of grouped data, we can use Excel by using the ∑symbol from the toolbar to take the sum the total of the data in the frequency column, relative frequency column and % frequency column. The screen for Excel looks like this –

  3. this box is called a cell and the celladdress is A1. this box has the cell address B16; meaning it is located at the intersection of column B and row 16

  4. this highlighted part is called a column

  5. this highlighted part is called a row

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

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

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

  9. 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).

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

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

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

  13. Note that B2 is the cell address of the data 2 and B9 is the cell address of 40. For the succeeding data, the formula is the same but B2 changes to B3, B4, etc while B9 is fixed; thus, the $ signs are used to indicate that 40 is a fixed value in the formula, B2/$B$9.

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

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

  16. Select Number then type 2 for decimal places and click ok

  17. 9. For the % frequency (%f), the values are equal to the rf column but they should only be expressed in % form. To do this with Excel, just type =C2 on cell D2, press enter and copy for the entire column as in step 7.

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

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

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

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

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

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

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

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

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

  27. That’s all folks! Good day!
