- What do I need to find?
How many more students chose chocolate than strawberry yogurt as their favorite?
- What information do I need to use?
the data about favorite yogurt flavor in the tally table
- How will I use the information?
I will count the tally marks. Then I will put the numbers in a frequency table
and compare the number of students who chose chocolate to the number of students who chose strawberry.
- Solve the problem
Count the tally marks. Record 7 for vanilla. Write the other flavors and record the number of tally marks.
To compare the number of students who chose strawberry and the number of students who chose chocolate, subtract.
8 - 4 = 4
So, 4 more students chose chocolate as their favorite flavor.
