• Nowhere, it is omitted

How would you plot the number 12 on a stem and leaf plot?

• 12 in the leaf only

• 1 in both stem and leaf

• 1 in the stem, 2 in the leaf

• 2 in the stem, 1 in the leaf

If you have two 18s in your data, how would you plot this on a stem and leaf plot?

• 8 in the stem, 1 in the leaf

• 1 in the stem, 8 in the leaf twice

• 1 in the stem, 81 in the leaf

• 18 in the stem, none in the leaf

What does a blank space or a line in a stem and leaf plot indicate?

• An error in plotting

• No numbers fall into that category

• A placeholder for future data

• All numbers are zero

• The most frequently occurring number(s)

• The difference between the highest and lowest values

How do you find the median in a stem and leaf plot?

• Cross off numbers from highest to lowest until one remains

• Identify the middle number in the leaf

• Cross off numbers from smallest to largest until one or two remain

• Average the stem values

What is the range of a dataset?

• The difference between the highest and lowest values

• The sum of all numbers
