# Tricky, Tricky, Tricky

Since mean and median appear on the GED® formula sheet, the GED® test is probably going to challenge you with tricky examples such as giving you data in ways you don't expect, asking you to work backwards, or throwing variables at you. Will you be ready?

## STEP 1: WATCH THE VIRTUAL CLASS VIDEO AND TAKE NOTES

### Make sure to note the following:

It won't surprise you I'm sure, to learn that the GED favors tricky mean, median, mode and range examples with hidden numbers, unexpected data forms, and working backwards. You'll need highly developed mathematical reasoning skills to tackle the average GED example.

Do you have a question about the class video, practice, or example problems? Post a picture to our FB group for immediate assistance. Be sure to include the lesson name and level in your post.

## STEP 2: COMPLETE ONE LEVEL OF PRACTICE

### EXPERIENCED

This Khan Academy exercise will give you practice solving what are, for most students, the trickiest type of mean problems: those where they give you the average and ask you to work backwards to find a missing number. These problems appear on the science as well as the math.
