Foundation November 2019 Paper 1 Q18
18. Gita is carrying out a survey to find out what people think of a proposed new road for Redville.
(a)
Gita decides to ask the first 20 people she meets at Redville bus station between 8 a.m. and 9 a.m. on a Monday morning.
Give two reasons why this plan is unlikely to produce reliable results. [2]
(b)
Here is a question from Gita’s survey:
| How often do you use your car? 1 – 2 ☐ 3 – 4 ☐ 4 – 5 ☐ 6 + ☐ |
Make two criticisms of Gita’s question. [2]
| Scheme | Marks | Comments |
|---|---|---|
| Two distinct reasons based on sample size, location, time or bias. e.g. ‘She needs to ask more than 20 people.’ or ‘She needs to vary the time that she asks people’ or ‘People at the bus station may be biased against cars’ | E2 | E1 for each valid reason; reasons need to be distinct; comments made regards time could be ‘hours spent’ or ‘time of day’ or ‘days of the week attended’ and these can be considered as distinct Allow e.g. ‘It’s only the first 20 people.’ (sample size) or ‘People might have to get on the bus.’ (location) or ‘It will be all school children at that time of day.’ (time or bias) Do not allow e.g. ‘People might lie’ or ‘People might not want to talk.’ |
| Scheme | Marks | Comments |
|---|---|---|
| Two distinct criticisms based on time frame and response boxes. e.g. ‘She has not said per day, per week etc’ or ‘The times are too vague’ or ‘There is nowhere to answer if you do not have a car’ or ‘4 is repeated’ | E2 | E1 for each valid criticism; criticisms need to be distinct (one comment only on response boxes and one on time frame omitted) Allow e.g. ‘It is not specific enough.’ (BOD time) or ‘People might not have a car.’ (Response boxes) |
