Nuffield Free-Standing Mathematics Activity Five a day © Department of Health

Do you eat five a day? What proportion of people do you think do this?   Do you think it depends on age or gender? Does government advice have any effect on diet? In this activity you will use statistical methods to answer such questions.

At the end of the activity What were the results of your survey? Did you use a suitable sample? Was it biased in any way? Was it large enough? Did you use the best measures of location and spread? Do your results make sense? Are they what you expected?
