English term or phrase: bias
Definition from Bureau of Justice Assistance:
The extent to which a measurement, sampling, or analytic method systematically underestimates or overestimates the true value of an attribute. FOR EXAMPLE, words, sentence structure, attitudes, and mannerisms may unfairly influence a respondent's answer to a question. Bias in questionnaire data can stem from a variety of other factors, including choice of words, sentence structure, and the sequence of questions.

Example sentence(s):
  • Increasing the sample size tends to reduce the sampling error; that is, it makes the sample statistic less variable. However, increasing sample size does not affect survey bias. A large sample size cannot correct for the methodological problems (undercoverage, nonresponse bias, etc.) that produce survey bias.
  • If, for example, the purpose is measuring average household income and the households without a phone have lower average income than others, ignoring the nonphone group will lead to an upward bias of average household income in the population. Of course the size of the bias would probably be limited in this example, because the group of households without a phone connection is small.
  • The Internet is an attractive mode of data collection to survey researchers due to cost savings and timeliness in comparison with other modes. However, survey estimates are subject to coverage bias if sampled persons with Internet access are systematically different from those without Internet access who were excluded from the survey.

систематична/методологична грешка

Definition from Scott Specialty Gas:
A systematic error in a process that causes all measured values to deviate from the true value by a consistent amount in a consistent direction (higher or lower than).

Example sentence(s):
  • Систематичните грешки се формират от фактори, постоянно действащи при многократно измерване на дадена величина, при еднакви условия. При повторни измервания систематичните грешки остават постоянни или се изменят по определен закон, нямащ статистически характер. Тези грешки не зависят от броя на измерванията. В основни линии се обособяват следните по–големи групи систематични грешки: - СУ “Св. Климент Охрид
