Which explanation should be considered when interpreting an observed association in an epidemiological study after consideration and control of selection and information biases? (choose one best answer) O The observed association may be due to chance alone. O The observed association may be due to problems in study design which result in selection bias and/or information bias and thus the association is spurious. O The observed association may be due to a third factor that is closely related to both the exposure and the disease in the study population. O The observed association may be causal (exposure causes disease).
