What is the problem with overlapping response boxes in a questionnaire?
Show answer
Overlapping boundaries make it unclear which box to select. For example, if the options are £5-£10 and £10-£30, a person spending exactly £10 could tick either box.
Why should questionnaire questions include a time scale when asking about spending habits?
Show answer
Without a time scale (day, week, month, year), respondents won't know which period to answer for, making responses inconsistent and unreliable.
What is a leading question in a questionnaire?
Show answer
A leading question tries to influence the respondent's answer, such as asking "Don't you agree..." which pushes people toward agreement.
Why is asking only friends a problem when designing a questionnaire survey?
Show answer
Friends may not be representative of the entire target population, leading to biased results.
Why is it a problem if questionnaire response boxes have gaps in coverage?
Show answer
Respondents whose answer falls in the gap have no appropriate option to select, making the data incomplete.
Why should response options in a questionnaire avoid being vague or too similar?
Show answer
Vague or similar options make it difficult for respondents to distinguish between choices, reducing the reliability of the data collected.
Why might asking only 10 people from the same class produce unreliable survey results?
Show answer
People in the same class are likely to be similar in age and characteristics, so there is no variety in the sample to represent a wider population.
Why is it not sensible to survey random people across the country about a restaurant opening in one town?
Show answer
People across the country are unlikely to dine at a restaurant in a specific town, so their opinions are not relevant to the business decision.
What problem arises when a questionnaire question does not include an option for disagreement?
Show answer
Respondents who disagree or have no opinion cannot accurately express their view, biasing results toward agreement.
What is the problem with sampling only Year 7 students for a survey?
Show answer
It does not include a range of ages.
Why is it important to include a "dislike" or "not applicable" option in a questionnaire?
Show answer
To avoid forcing respondents who don't engage with the topic to give misleading answers.
