Activities
- Use the table below showing the results of a survey of high school students regarding sports and playing an instrument to answer the questions.
- How many total students were surveyed?
- What does the 21 represent in the table?
- Complete the two-way table below:
- Calculate the relative frequency by row for the table below:
- A group of middle school students were asked which sport they play during the summer. The results are displayed in the Venn diagram below. Use the Venn diagram to construct a two-way table.
- Javier was curious whether students in middle school and high school preferred the same type of phone. He surveyed 100 students and found the following:
- 27 of the 50 middle school students preferred iPhones to Android phones.
- 24 of the 50 high school students preferred Android phones over iPhones.
- Use the information Javier found to construct a two-way table and calculate the relative frequency by column (to the nearest hundredth).
- According to the data, would you say that middle school students and high school students have similar or different preferences? Explain
- Markita wanted to know if there was an association between the number of people that purchased popcorn for a movie and those that purchased a drink. She observed 120 people walking into the movies and recorded her results. Use her results below to construct a two-way table including the relative frequencies (to nearest hundredth). Use the table to draw a conclusion.
- Out of 98 people with popcorn, 19 did not have a drink.
- 11 people walked in without popcorn or a drink
Answer Key/Rubric
- Answers as follows:
- 116 students
- Twenty-one is the number of students that play an instrument and a sport.
- Table should be filled in as follows:
- Acceptable responses may include, but are not limited to:
- The students have pretty similar preferences as seen by the relative frequencies calculated being so close.
- Acceptable responses may include, but are not limited to:
- Two-way Table:
- Conclusions:
- Those who purchased popcorn were more likely to purchase a drink with it.
- More people were likely to purchase a drink than go without.
- Those who did not purchase popcorn were equally likely to get a drink or go without.
