Exploring Standard Deviation and Mean with Desmos

This video tutorial provides a quick guide on using Desmos to calculate the standard deviation and mean of a data set. It begins with opening Desmos and setting up a table to input data. The tutorial then demonstrates how to calculate the standard deviation using the 'stdev' function and find the mean using the 'mean' function. Additional statistical functions available in Desmos, such as finding the total, median, minimum, maximum, and quartiles, are also mentioned. The tutorial aims to refresh viewers' knowledge from a previous lesson and assist with homework tasks.
