Questions On Margin Of Error - 1532 Words

What is margin of error? Margin of error is a common summary of sampling error that quantifies uncertainty about survey results. Three pieces of data are needed to express the â€Å"confidence interval,† : statistic, confidence level, and margin of error. Confidence Interval is usually stated in the following format: 95 percent confidence intervals, or accurate 19/20 times with a margin of error of +/- 5%. This means that 19 out of 20 times it is expected that the mean of the survey result (stats) will fall within 5% above or below the true value. There are strict parameters that determines on which survey results a Margin of Error disclaimer can included.

Integrity of Reporting (a) Researchers must not knowingly allow the dissemination of conclusions from a market research project which are not adequately supported by the data. They must always be prepared to make available the technical information necessary to assess the validity of any published findings. (b) This entails that: 1. Researchers must recommend those techniques and methodologies which are appropriate to the objectives of the research, avoiding those which they believe may give misleading results. 2. Researchers must not provide or allow without protest, interpretations of the research that are inconsistent with the data. 3. Researchers must not present research results with greater confidence than the data warrants. Instead, as responsible professionals, members must point out the relevant limitations of the research. This includes but is not limited to the following guidelines: i. Disclosing relevant potential sources of error, both sampling and non-sampling (e.g. response, non-response, measurement, coverage, etc.). ii. Being explicit about the assumptions
