- Abstract
- Scharakteryzowano zagadnienie błędów w badaniach statystycznych, ze szczególnym uwzględnieniem błędu sondażowego. Omawiany temat zilustrowano przykładami błędów nielosowych napotykanych w badaniach opinii publicznej.
There are many reasons for errors occurring in public opinion polls. Avoiding or measuring these errors is extremely difficult. Groups such as TNS OBOP, PBS, Gfk Polonia etc., which research the Polish market, only show a random error (most frequently %), which is relatively easy to count, show and explain. Unfortunately, there are many more issues to be considered. One of significant examples is the opinion polls before the elections in 2005 and 2007 in Poland. The discrepancy between the polls and the elections results shows a huge need to improve the way of measuring the polls. Moreover, the groups which research the market should inform people more precisely about the tools they use. The fact that there are systematic errors right next to random errors is worth mentioning. Systematic errors have an additional impact on the results of statistical researches. Systematic errors are difficult to detect and cannot be analyzed statistically. An opinion poll can be seen as a professional way of showing peoples' opinion on nearly every subject. However, we need to treat our researches seriously, taking all the aspects, like systematic errors, into consideration, as it is done in the United States of America, where the Gallup Organization is doing its job really well.
