Random and systematic error are two types of measurement error. Systematic errors include personal errors, instrumental errors, and method errors. reporting bias: related to issues of social desirability or sensitivity, blind the study participants as to the hypothesis under investigation, use questionnaires that are carefully constructed; ask specific as well as multiple questions; for socially sensitive questions (alcohol/drug use) use a self-administered questionnaire instead of an interview; if possible, asses past exposures from biomarkers or from pre-existing records, faulty function of an instrument (biased scale giving a higher/lower reading that actual); inappropriate use of technique or tool to objective of measurement (endoscope not reaching to the site of interest and giving false info from a distance; leading questions), sampling errors, measure error, individual biological variation, increase sample size, repeated measurements, in epi measurements corresponds to the reduction of random error (obtaining similar results with repeated measurements; reliability, repeatability, reproducibility, consistency, agreement), the degree to which a measurement/estimate based on measurements, represents the true value of the attribute that is being measure (obtaining results close to the truth; validity, conformity, lack of bias), the degree to which a variable has nearly the same value when measured several times (comparison among repeated measure) (2023, February 13). . 1.
