I greet you this day,
You may use these calculators to check your answers. You are encouraged to solve the questions first, and check your answers. These topics are covered in my Notes and Videos on Correlation and Regression.

Comments, ideas, areas of improvement, questions, and constructive criticisms are welcome.
You may contact me. Please note that I may not respond to every message.
If you are my student, please do not contact me here. Contact me via the school's system.
Thank you for visiting.
