Standard Deviation calculator made in Python with tkinter GUI. It also calculates the mean, median and variance of the input data.
Python version 3.6 or newer is required as well as the tkinter library. On Windows the tkinter library should
already come together when you installed Python. On Linux distros it may be needed to install it separately.
You should search on the internet for the correct way to install it for your desired distro.
To execute the program simply run the main.py file.
