Final answer:
Three errors in the survey were identified and explained, along with three ways to improve it.
Step-by-step explanation:
The question asks for three errors in the way the survey was conducted. Three examples of errors in the survey could be:
- Failure to use a representative sample: If the survey was conducted only among a specific age or gender group, the results may not accurately represent the entire population.
- Inadequate sample size: If the sample size was too small, the survey may not provide statistically significant results.
- Biased question wording: If the questions were worded in a way that influenced the respondents' answers, the survey may be biased and the results may not reflect the true opinions of the participants.
When improving the survey, three suggestions could be:
- Using a random sampling method: This would ensure that every individual in the target population has an equal chance of being selected for the survey.
- Increasing the sample size: A larger sample size would provide more reliable and accurate results.
- Using unbiased question wording: The questions should be phrased in a neutral and objective manner to avoid influencing the respondents' answers.
