A large university is considering building additional housing for graduate students, but they will only do this if polling data can demonstrate that more graduate students want on-campus housing. The university currently provides housing for 10 percent of its graduate students to live on campus. The housing office decides to survey a random sample of graduate students, and 62 out of the 481 respondents say that they are looking for housing on campus. Do these data provide convincing evidence to support construction of more on-campus graduate student housing? Be sure to use all steps of the PHANTOMS process to reach your conclusion.

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.
