How to Turn On Frequency on Canon Calculator

Updated 6 November 2026 · Standard formula, shown below

This guide shows you how to access and use the frequency (FRQ) feature on Canon scientific and statistical calculators. The frequency function lets you enter a value once and tell the calculator how many times it occurs, which is essential for quickly computing mean, standard deviation, and other statistics from grouped data. You’ll need your Canon calculator (models like F-715SG, F-792SGA, or similar) and the data you want to analyze.

What You’ll Need

A Canon scientific or statistical calculator with a frequency function (check the manual or look for a ‘FRQ’ or ‘FREQ’ label on the keypad).
Your data set, ideally organized as values and their frequencies.
Fresh batteries, if the display is dim or unresponsive.

Step-by-Step

Turn on the calculator by pressing the ON or AC button.
Enter STAT mode. Press the MODE key repeatedly until you see the STAT menu. On most Canon models, you’ll press MODE then 2 for STAT. The screen should show ‘SD’ or ‘STAT’.
Select the statistical calculation type. After entering STAT mode, you may need to choose between ‘1-VAR’ (one-variable statistics) and ‘2-VAR’ (two-variable statistics). For frequency, you’ll typically use 1-VAR. Press 1 or the corresponding number.
Open the data entry screen. You’ll see a table with columns labeled X and FREQ (or FRQ). If you don’t see the FREQ column, you need to enable it.
Turn on the frequency column. Press SHIFT (or 2NDF on some models) followed by SETUP (or MODE again). Scroll down to find ‘Frequency’ or ‘Freq.’ Select ‘On’ by pressing 1 or the corresponding number. The FREQ column should now appear in the data table.
Enter your data. For each data value, type the number and press = (or EXE). Then type the frequency for that value and press = again. The cursor moves to the next row automatically.
Calculate statistics. After entering all data, press AC to exit the data entry screen. Then press SHIFT followed by 1 (or STAT key) to open the statistics menu. Choose ‘1-VAR’ or ‘Var’ and then select the statistic you need, such as mean (x̄), sample standard deviation (sx), or population standard deviation (σx).
Read the result. The calculator will display the computed value. Press AC to clear and repeat for other statistics.

Common Mistakes

Forgetting to turn on the frequency column before entering data. If you enter data and then enable frequency, the calculator may not apply it correctly.
Entering frequencies as separate data points instead of using the FREQ column. For example, entering 5, 5, 5, 5 for a value of 5 with frequency 4 is wrong; you should enter 5 once and set FREQ to 4.
Using the wrong statistical mode (e.g., 2-VAR instead of 1-VAR) for single-variable data.
Not clearing previous data before starting a new problem. Always press SHIFT + CLR (or MODE then CLR) to reset the STAT memory.
Misreading the frequency column – make sure the cursor is on the FREQ cell when entering the frequency.

Tips

Check your calculator’s manual for the exact key sequence, as it varies slightly between Canon models.
Use the frequency feature for large data sets with repeated values – it saves time and reduces entry errors.
After finishing, turn off the frequency option if you need to do regular calculations, to avoid confusion.
Practice with a small data set (e.g., values 2, 3, 4 with frequencies 1, 2, 3) to verify the calculator gives the correct mean (here, (2*1+3*2+4*3)/(1+2+3) = 20/6 ≈ 3.333).
Use the ‘S-VAR’ menu to access all statistics at once if your model supports it.

Troubleshooting

Frequency column not showing: Re-enter SETUP and ensure ‘Frequency’ is set to ‘On’. If it still doesn’t appear, try resetting the calculator (SHIFT + CLR + 1) and then enabling it again.
Wrong results: Double-check that you entered each value and its frequency correctly. Clear all data and re-enter.
No STAT mode: Some Canon models require pressing MODE multiple times to cycle through modes. Keep pressing until you see ‘STAT’.
Key not responding: Check if the battery is low. Replace it if needed.
FREQ column shows but data is not using it: Make sure you are in the correct data entry screen. Press SHIFT + 1 and choose ‘Data’ to view the table.

Frequently Asked Questions

What does the frequency function do on a Canon calculator?

It lets you enter a data value once and specify how many times it appears in the data set. This is useful for grouped data or when you have repeated values, as it avoids entering each occurrence individually.

How do I turn off the frequency function?

Go to SETUP (SHIFT + MODE), scroll to ‘Frequency’, and select ‘Off’. The FREQ column will disappear from the data table.

Can I use frequency with two-variable statistics?

Yes, most Canon calculators that support frequency allow it in both 1-VAR and 2-VAR modes. The process is similar – you’ll have FREQ columns for both X and Y data.

Why does my calculator show ‘Error’ when I try to calculate statistics?

This usually happens if you haven’t entered any data, or if you have entered data but not exited the data entry screen. Press AC to exit, then try again.

Does the frequency function affect the mean and standard deviation?

Yes, it weights each value by its frequency. The mean becomes the sum of (value × frequency) divided by the total frequency, and the standard deviation is calculated accordingly.

Is the frequency function available on all Canon calculators?

No, it’s typically found on scientific and statistical models, not on basic four-function calculators. Check your model’s manual or look for ‘FRQ’ on the keypad.
