Stature

Comments (0)

The Nuffield Foundation provide this resource where students use simulated stature data for men and women in eight countries to draw histograms and look for general results, as manufacturers need to take these into account when they design products.

This is mainly intended as an introduction to the normal distribution, but the extension also gives an opportunity for using the data after students have learnt how to use a standard normal table to fit a normal distribution.

To be able to complete the activity students must be able to:

• draw and interpret histograms

• calculate and interpret the mean and standard deviation of a sample

• use linear interpolation in a grouped frequency table or a histogram to estimate the number of items within a range of values

• find percentiles from a grouped frequency table or histogram

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
