    Avoiding bias in surveys

    Using random sampling techniques to get a fair, unbiased representation of the population.

    Suspecting bias in data

    When you notice something might be skewed, double-check your work and get a second opinion from others.

    Biased dataset results

    They're worse than no results because they can lead to incorrect conclusions and choices.

    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.
