How to Use the Frequency Table Calculator

The Frequency Table Calculator allows you to compute various statistical measures for a list of numbers, including frequency distributions, mean, median, mode, and standard deviation. Follow the steps below to use the calculator effectively.

Step 1: Enter Your Numbers

  • Locate the input field labeled ‘Enter Number’.
  • Input your number into the field. Ensure that each number you enter is within the range of -1,000,000 to 1,000,000.
  • Press Enter after typing each number to add it to your list.
  • Continue adding numbers until you’ve entered the entire dataset you wish to analyze.

Step 2: Choose the Class Interval Type

  • Find the input field labeled ‘Class Interval Type’.
  • Select the desired option from the dropdown menu:
    • Automatic: The calculator will automatically determine the class interval size.
    • Custom: You will specify a custom interval size.

Step 3 (Optional): Define Custom Interval Size

  • If you selected Custom in the previous step, another input field will appear labeled ‘Custom Interval Size’.
  • Enter a positive number between 0.1 and 1000 to define your custom interval size.

Step 4: Review the Results

Once you’ve entered your data and selected interval options, the calculator will compute and display the following results:

  • Frequency Distribution: A breakdown of numbers into frequency intervals.
  • Relative Frequency: The percentage representation of each frequency relative to the total count.
  • Cumulative Frequency: The cumulative sum of the frequencies up to each interval.
  • Mean: The average of your dataset.
  • Median: The middle value when the numbers are sorted in ascending order.
  • Mode: The number that appears most frequently in your dataset.
  • Standard Deviation: A measure of the amount of variation or dispersion in your dataset.

Conclusion

By following these steps, you will be able to successfully use the Frequency Table Calculator to analyze your data using various statistical methods. Be sure to check that your data is correctly entered and that you’ve chosen suitable interval settings to obtain accurate results.
