Practice Problems
Try them, get help one step at a time, then print how it went.
Practice: try it, then get help one step at a time
Describe direction, form, and strength in words, and read what r says. Hint gives a nudge, Show next step shows one worked step at a time, Reveal answer checks, and Hide help / start over clears the card.
My results
Finished the practice? Print a page that shows each question, what you typed or chose, the correct answer, and how it went. Good for showing a teacher or keeping in a folder.
Exit ticket
On paper or an index card. Use the math word and the plain-English word.
- Describe a scatter plot three ways. What are the three things?
- What does r = 0.97 tell you?
- Which is stronger, r = −0.8 or r = 0.5? Why?
- What does the graphing window show?

- Direction, form, and strength.
- Positive direction, a very strong relationship, and a line fits well.
- r = −0.8. Strength is the size; the sign is only the direction.
- Roughly the domain (along the bottom) and the range (up the side) of the data.
