This tool helps you calculate the standard deviation using a TI-84 calculator.
How to Use the Standard Deviation Calculator
To use the calculator, follow these steps:
- Enter your data set in the text field provided. Ensure the values are separated by commas.
- Click the “Calculate” button.
- The Standard Deviation will be displayed in the result field below.
How the Calculator Works
The calculator follows these steps to compute the Standard Deviation:
- First, it converts the input string into an array of numbers.
- Next, it calculates the mean (average) of the numbers.
- It then computes the variance by averaging the squared differences from the mean.
- Finally, it computes the Standard Deviation as the square root of the variance.
Limitations
The current calculator has the following limitations:
- The input must be a comma-separated list of numbers.
- It does not handle empty input or inputs that contain non-numeric values well. Proper error messages should be handled but are currently basic.
- The standard deviation result is rounded to four decimal places.
