Exploring Patterns of Association in Two-Way Tables

The video tutorial covers an activity involving data collection and analysis. Students conduct a survey to determine hand preference and its impact on sports participation. The tutorial guides students through creating a two-way table, calculating totals, and determining relative frequencies. It emphasizes interpreting data and understanding percentages, concluding with a final analysis of the results.

What is the primary focus of Activity 2?

• Studying the anatomy of the human hand

• Exploring the geography of sports around the world

• Learning about the history of sports

• Understanding the concept of frequency and ratio

What are the two variables displayed in the two-way table?

• Age and sports participation

• Hand favored and sports participation

• Height and weight

• Gender and sports preference

• Right hand

• Both hands equally

• Left hand

• No preference

How many total people participated in the survey?

• 24

• 33

• 63

• 97

What does the relative frequency represent?

• The total number of occurrences

• The difference between the most and least frequent occurrences

• The average number of occurrences across all categories

• The ratio of occurrences within a category to the total of the category

What percentage of left-handed people participated in team sports?

• 66.5%

• 50%

• 67%

• 17%

How is the relative frequency calculated for each category?

• By dividing the total occurrences by 100

• By adding the occurrences of all categories

• By dividing the part by the whole of each category

• By multiplying the occurrences by the total number of categories

Which group had the highest percentage of sports participation?

• All had equal participation
