Response Bias Project SURVEYS Activity In this Activity, you will design and conduct an experiment to investigate the effects of response bias in surveys. You may choose the topic of your surveys, but you must design your experiment so that it can answer at least one of the following questions: Can the wording of a question create response bias? Do the characteristics of the interviewer create response bias? Does anonymity change the responses to sensitive questions? Does manipulating the answer choices change the response? Response Bias Project 10 points – Write a proposal describing your experiment. Be sure to include: (1) your chosen topic and which of the above questions you are going to answer. (2) A detailed description of how you will obtain your subjects (minimum of 50)! (3) What your survey questions will be and how they will be asked (4) A clear explanation of how you will implement your experimental design. (5) Precautions you will take to collect data ethically Take your surveys next week during your classes – make sure you get permission ahead of time from your teachers! Response Bias Project - Surveys Please make sure you are using one of our sampling techniques – SRS, stratified, or cluster (don’t make up your own). You need to randomize your process of selecting students in your classes. Response Bias Project - Powerpoint Introduction – 20 points Describes the context of the research (discuss response bias and what we are trying to see in our survey) Has a clearly stated question of interest (this is one of the four questions) Provides a hypothesis about the answer to the question of interest (What do you believe will occur as a result of your survey?) Picture of your survey and your different questions. Response Bias Project - Powerpoint Data Collection – 20 points Method of data collection is clearly described Includes appropriate randomization Describes efforts to reduce bias, variability, confounding (what could possibly affect what we are trying to see and how could you eliminate that?) Quantity of data collected is appropriate (minimum: 50 students) Response Bias Project - Powerpoint Graphs and Summary Statistics – 10 points What were the results of your survey? Appropriate graphs are included (to help answer the question of interest) – Bar Graph (Frequency) or Table Graphs are neat, clearly labeled, and easy to compare Appropriate summary statistics are included Summary statistics are discussed and correctly interpreted (What conclusion can you draw? Provide appropriate graphical and numerical evidence to support your answer.) Response Bias Project - Powerpoint Conclusions – 20 points Uses the results of the study to correctly answer question of interest Discusses what inferences are appropriate based on study design Discuss any problems you encountered and how you dealt with them. Shows good evidence of critical reflection (discusses possible errors, shortcomings, limitations, alternate explanations, etc.) Response Bias Project - Powerpoint Poster Presentation – 20 points Clear, holistic understanding of the project Poster is well organized Poster is visually appealing (design, pictures) Link for examples http://www.statsmedic.com/blog/response-bias-project
