SAT Math: How to Solve Standard Deviation Problems

Описание: Hi!

Problems start at 00:04:18.

In the beginning of the video, I explain what standard deviation (SD) is and how it's tested on the SAT. Then, I explain SD with examples (00:01:19 & 00:03:22) before rolling into sample problems from Khan Academy.

There is usually a SD problem on the SAT. It’s usually conceptual, i.e. no calculations are involved. This video is also great for anyone who’s just trying to understand SD without doing the math.

The problems go from easy to hard and also involve other statistical concepts (mean, median, range):
Problems 1 & 2 are warm up questions in understanding SD.
Problems 3-5 are more likely to be seen on the real exam.
Problems 4 & 5 are highly recommended

And to everyone watching, thank you! I appreciate the support & hope these videos are helpful.

Good luck!
