7Da Focus on: Continuous variation 2 a) Explain why Marks & Spencer measured so many women. Taking a smaller sample size may give them some odd sizes since by chance they may have picked more women who have a measurement that is very different from most women.

Continuous variation 2 b) What measurements do you think they took? 7Da Focus on: Continuous variation 2 b) What measurements do you think they took? For example: waist, arm length, bust. c) What relationships do you think they looked for in the data? For example: neck size compared with arm length.
