Am I average?

Problem

Wilbur's Work Stuff Inc is a company which is producing a new line of clothes. The clothes are designed to be worn to work by those in the 15- to 45-year age group. In order to target their advertising, they have taken a sample of some people and want to find out what characteristics define the ‘average’ person in this group. 

 

Plan

Working in groups, you are going to investigate what defines the average person by using the information collected for the SURF for Schools dataset.

 

Data and Analysis

The group needs to:

  1. Construct a frequency table for each variable in the dataset. Remember that some variables will need to be grouped.
  2. Draw a different type of graph for each variable on the dataset. You must draw at least one histogram, one bar graph and one pie graph.
  3. Do at least one calculation for each variable. Choose from: mean, median, mode, proportion and range.

Conclusion

 

  1. Write a sentence about what you have discovered for each variable.
  2. Design a poster which shows the characteristics of the average person from the dataset.
