TL;DR

This tutorial explains how to calculate and plot standard deviation using Python.

Transcript

what's going on guys welcome to the next part of our standard deviation tutorial series here or mini series uh where we left off we were actually calculating standard deviation now we need to go ahead and actually just plot it on up if you don't already have uh the sample code it is on the link in the description and just make sure you C uh highlig...

Questions & Answers

Q: What is the purpose of this tutorial?

This tutorial aims to teach viewers how to calculate and visually plot standard deviation using Python programming language.

Q: How is the code structured to calculate standard deviation?

The code defines a function called DefineStandardDeviation, which takes in a time frame and an array of data. It calculates the standard deviation for each time frame and appends the values to separate arrays for dates and standard deviations.

Q: How are the standard deviation plots generated?

After defining the function and calculating the standard deviation, the code uses the plot function from the "a2" module to display the date and corresponding standard deviation values on a graph.

Q: What do the standard deviation plots of eBay and Apple stocks show?

The plots demonstrate how the volatility of the stocks changed over time. In the case of Apple, the plot shows increased volatility during specific periods.

Summary & Key Takeaways

• The video is a continuation of a tutorial series on standard deviation, focusing on plotting the calculated values.

• The instructor provides a code snippet that defines a function to calculate standard deviation and plots the results.

• Examples of standard deviation plots for eBay and Apple stocks are shown, highlighting periods of increased volatility.
