Student learning outcomes

The student will demonstrate the systematic sampling technique.
The student will construct relative frequency tables.
The student will interpret results and their differences from different data groupings.

Movie survey

Ask five classmates from a different class how many movies they saw at the theater last month. Do not include rented movies.

Record the data.
In class, randomly pick one person. On the class list, mark that person’s name. Move down four names on the class list. Mark that person’s name. Continue doing this until you have marked 12 names. You may need to go back to the start of the list. For each marked name record the five data values. You now have a total of 60 data values.

For each name marked, record the data.

Discussion questions

Is one of the tables “more correct” than the other? Why or why not?
In general, how could you group the data differently? Are there any advantages to either way of grouping the data?
Why did you switch between tables, if you did, when answering the question above?
