Table 1.19 Frequency of Number of Movies Viewed
Each of the following questions 1-7 are 4 points each.
- Using the tables, find the percent of data that is at most two.
- Using the tables, find the percent of data that is at most three.
- Using the tables, find the percent of data that is more than two.
- Using the tables, find the percent of data that is more than three.
Discussion Questions – Be sure to answer ALL 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?
