JACKET SURVEY
A school decided to change the school jacket to be worn by both male and female students. The school
committee would like to determine which of three new jacket designs is preferred by the school
community. The committee can provide images, pricing and information about the material.
1 Determine how you would gather information to determine the preferred choice.
2 Who would need to be surveyed?
3 From the list below, discuss the relevance and merit of each question.
Do you like the current school jacket?
Which of the three jacket designs do you prefer for style? A B C (Tick only one.)
Briefly describe what you like and/or dislike about each of the new jacket designs.
Which of the three jacket colours do you prefer? A B C (Tick only one.)
Rank the designs from 1 to 3 (1 being your most preferred and 3 being your least preferred).
A B C
Do you like wearing school uniform? Yes No
Would you wear a uniform or your normal casual clothes to school if given a choice?
What is your favourite colour for clothing?
Do you always wear a jacket to school?
Can you afford each of the choices? Yes No
Which of the three jacket designs seems the best value for money? A B C (Tick
only one.)
4 Construct suitable questions then design a survey or surveys that will enable you to gather the data
to solve the problem. Would everyone be given the same survey?
5 Determine how the data is to be represented and analysed.
6 Determine whether you would conduct a census or a survey. If a survey, how would you select
your samples? How would you administer the census or survey?
7 Conduct a small trial of your survey by gathering some images of school jackets, hats, prices etc.
8 From the trial, discuss any changes you would then make to your study, either by changing the
questions, the recording techniques or the sampling method.
