Question
question 3 1 pts researchers at osu are conducting a study about student stress. the researchers survey the students who visit the campus wellness center during the week in which final exams take place. after analyzing the survey responses, the researchers report that most osu students experience unusually high levels of stress during finals week. what does it mean if we refer to this study as being biased? the researchers failed to predict the outcome of the study in advance. the sensitive nature of the topic may cause some students to underreport their stress levels. the timing of data collection—during finals week—means that some students might have been too busy to complete the survey. the sampling method overrepresents students who are already seeking help at the wellness center. the sample is clearly not representative of the entire university.
A biased study has non - representative samples. Here, sampling students at the wellness center during finals doesn't represent all OSU students.
