Practice Problems

Try them, get help one step at a time, then print how it went.

Practice: compare and write

Choose the statistics that fit the shape, compare centers and spreads, fill the sentence frame, and compare with the model answer. 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.

  1. What are the five steps for comparing groups?
  2. Two classes have means 83.3 and 83, medians 87.5 and 83, IQRs 12.5 and 5. The first is skewed with an outlier. Which scored higher, and which was more consistent?
  3. Why not just compare the means?
  4. Each list is a whole class. Sigma or s?
Check your exit ticket
  1. Same scale; shape; statistics that fit (same kind for both); compare centers and spreads; sentences in context.
  2. 1st period scored higher by the median; 4th period was more consistent by the IQR.
  3. 1st period's mean was pulled down by the outlier 34; the median fits a skewed shape.
  4. Sigma.
