Any two of the following: e.g. 1. Reason for suitability of the location. ‘Conducting the survey outside a travel agent is biased as people using a travel agent are likely to go abroad.’ ‘She has only surveyed outside her local travel agent.’ 2. Reason for suitability of the sample size. ‘35 is not a big enough sample and is unlikely to be a true representation of the population.’ 3. Reason for suitability of the time the survey is carried out. ‘Cara should conduct the survey at various times of the week/weekend not just Tuesday afternoon to ensure a full cross section of people are included.’	B2	B1 for one of the correct reasons Note: Two reasons may be given in one part of the answer space. Allow e.g. ‘Regular travellers go to a travel agent.’ ‘The location is biased.’ ‘They will be booking holidays.’ ‘She is staying in one area.’ ‘Only asked 35 people.’ ‘Not enough people asked.’ ‘Most people book holidays at the weekend.’ ‘Most people work in the week.’ ‘It’s only one afternoon.’ ‘Not everyone will use the travel agent on a Tuesday.’ ‘She is doing it once.’ ‘It’s only a Tuesday afternoon.’ Do not allow ‘Biased.’ ‘It’s a Tuesday afternoon.’ ‘Some people may not use a travel agency to book holidays abroad.’ ‘Some people may book online.’ ‘It’s an odd number of people.’
