English term

bias

GBK English to Danish Science Mathematics & Statistics
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 sentences:
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. (stattrek.com)
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. (rand.org)
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. (European Survey Research Association)

bias

Definition from Den Store Danske Encyklopædi:
bias, (am., af fr. biais 'skrå', måske af gr. epikarsios 'skrå, skæv'), statistisk udtryk for den systematiske fejl (skævhed), der kan opstå ved estimation i en statistisk model. Estimation uden bias kaldes central.
Example sentences:
Som eksempel på bias kan nævnes, at telefoninterviews hyppigere giver svar fra typiske hjemmemennesker end fra folk, der tit går i byen, hvorved fx befolkningens tv-forbrug bliver overvurderet, mens antallet af restaurationsbesøg bliver undervurderet. (Den Store Danske Encyklopædi)
Bias kan også være en systematisk fejl, for eksempel i den måde et spørgeskema er udformet på. Hvis skemaet ikke har alle relevante svarmuligheder, kan den person, der skal udfylde skemaet, blive udelukket fra at svare korrekt. (Dansk Folkeoplysnings Samråd)

usikkerhed

Definition from own experience or research:
Idet den selektive observations metode og indsamling af historiske data var behaeftet med en signifikant usikkerhed, blev hypotesen afvist i et 99% konfidens interval
Example sentences:
I de tilfælde hvor det enkelte nøgletal er behæftet med en kendt statistisk usikkerhed tager beregningsmetoden højde for den statistiske usikkerhed ved hvert enkelt nøgletal, hvorved der opnås en relativt retvisende samlet rang-stilling af det enkelte sygehus i forhold til de øvrige sygehuse. (Google)
Det er første gang hjertemuslingeforekomsterne i det ydre løb i Grådyb måles, og bestanden består alle af fiskbare hjertemuslinger, men forekomsterne er meget små og på kun 70 ± 43 tons på Grådyb syd og noget højere på Grådyb nord 337 ± 555 tons (95% konfidensinterval). Usikkerheden på målingerne og dermed i beregningerne er meget store. En måde at mindske usikkerheden vil være at øge antallet af prøvetagninger (Google)
Peer comment(s):
disagree Anna Haxen : Usikkerhed means uncertainty, which is not the same as bias.

Hi Anna, i am still not quite sure what is wrong with "uncertainty/usikkerhed" but I have been thinking that "dragning" may be an alternative to "usikkerhed". What do you think? Mvh Lisbeth
