lethal. Sampling methods are important because errors can result in lethal exposure of mycotoxins to individuals. Sampling involves using portions of lots to represent mycotoxin levels in the entire lot. There is a lot of uncertainty because the level of contamination in one peanut kernel can be high‚ but the number of contaminated peanut kernels in the lots may be very low. Different sampling techniques may have varying levels of possibilities for error‚ so it should be taken into account when setting

survey practices. • What was the population? That is‚ whose opinions were being sought? • How was the sample selected? Look for mention of random sampling. • How large was the sample? Even better‚ find out both the sample size and the margin of error within which the results of 95% of all samples drawn as this one was would fall. • What was the response rate? That is‚ what percent of the original subjects actually provided information? • How were the subjects contacted? By telephone? Mail? Face-to-face

validity? Polling relies on the principles of inferential statistics‚ which states that we can draw inferences about a set by examining a randomly assembled subset. Random selection is key. 3. How does sample size and margin of error correlate? Margin of error tells us how close to the full population we can expect the sample to take us. They correlate because a sample tells us how many is selected at random from a size of random samples. 4. What factors contribute to an individual’s
