    Study Notes

    Common Biases in Surveys and How to Avoid Them

    • Survey bias can occur due to factors like order bias, leading questions, and recall bias, which can skew survey results.
    • Order bias can be mitigated by randomizing the order of questions or answers in survey software.
    • Leading questions can influence outcomes and should be carefully reviewed to avoid bias.
    • Recall bias is due to people's inability to accurately remember past events, and can be minimized by using short, specific, and multiple-choice questions about the past.
    • Culture bias arises from different cultural perspectives and can be addressed by involving local individuals in survey administration and translation.
    • Localization groups can ensure that survey data is appropriate for specific cultural areas.
    • Confirmation bias leads people to seek out evidence that supports their existing beliefs, and can affect survey results.
    • To minimize confirmation bias, analysts should approach surveys with an open mind and healthy skepticism.
    • Observation bias occurs when participants alter their behavior due to being watched, leading to skewed results.
    • Informal approaches and assurance of data anonymization can help mitigate observation bias.
    • Selection bias occurs when the sample of survey participants does not represent the whole target population.
    • It is essential to ensure that the selection of survey participants is not biased and favors subsets of the general population.
