Cell Phone Data Checklist
A youth centre asked 60 young people whether they own a mobile phone. The survey included 20 people in each age group. Use the results below to investigate how phone ownership varies by age. The survey is fictional, and the results describe only the people surveyed.

Explore the results
Use evidence from the survey table. Show calculations where you can.
1.Before calculating, predict which age group will have the greatest proportion of phone owners. Give one reason for your prediction.
2.What type of data is the response “own a phone” or “do not own a phone”: numerical or categorical? Explain briefly.
3.How many people were surveyed altogether? Use the table to calculate the total.
4.Calculate the proportion of phone owners in each age group as a percentage. Which group has the greatest percentage?
5.How many more phone owners were there than non-owners in the 13–14-year group?
6.Choose the best statement supported by the table.
- The proportion of phone owners is higher in each older age group.
- Every person aged 15–16 owns a phone.
- There are more 11–12-year-olds in the survey than people in the other age groups.
- Age has no relationship to phone ownership in this survey.
7.A student says, “This proves that getting older causes people to own a phone.” Is that conclusion justified by this survey? Explain why or why not.
8.Suggest one way to make a follow-up survey more representative of young people across Aotearoa New Zealand.
9.Check your prediction from Question 1 against the percentages. Was it supported by the results? State one piece of evidence.
