Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

Suppose you recruit the next 100 people who visit the DCC cafeteria to participate in a survey. One of the questions you ask is whether the student eats on campus (i.e., in the cafeteria) regularly, and you want to use the sample proportion to estimate the value of the (population) proportion of all DCC students who eat on campus regularly. Do you think this sampling method is likely to be biased? If so, in which direction? This sampling method is not likely to be biased and will produce a representative sample of DCC students. This sampling method is biased and is likely to yield an overestimate for the population proportion. This sampling method is biased and is likely to yield an underestimate for the population proportion.
