Student activity sheet 9 introduction to statistical bias and variability

In this series of activities on evaluating racial bias in traffic stops and searches, students calculate the probabilities of drivers of different races being searched at traffic stops, and compare their findings to census data to determine if the numbers represent random sampling or show evidence of racial bias.

Introduction to Statistics and Probability Students encounter variability in their lives, in their science and social studies coursework, and in the news media. Study of the topics in statistics and probability gives students methods for summarizing data, introduces students to mathematical models for random phenomena, Guidelines for Assessment and Instruction in Statistics Education (GAISE) Reports. Participants in the Guidelines for Assessment and Instruction in Statistics Education (GAISE) project have created two reports of recommendations for introductory statistics courses (college level) and statistics education in Pre-K-12 years. Bias, variability, and shape Both bias and variability describe what happens when we take many shots at the target. High variability means that repeated shots are widely scattered on the target. Repeated samples do not give very similar results. The lesson about center and spread is clear: given a choice of statistics to All people should have access to education, but many college students today cannot afford textbooks. Matt has written three open source OER free textbooks for students.

Statistical Studies: Sources of Variability III.C Student Activity Sheet 10: Statistical Bias in Research Studies and Polls Charles A. Dana Center at The University of Texas at Austin Advanced Mathematical Decision Making (2010) Activity Sheet 10, 5 pages 82 Statistical bias in experimental studies can result from several factors. I tell students we will be revising the questions they developed in the previous lesson and agreeing on the procedures for giving the survey to students. I want students to critically analyze the wording of the survey questions that they have created. To introduce students to the idea of question bias, I pass out one sheet of paper to each student. About This Quiz & Worksheet. Students can use these assessments to check their understanding of statistical variability. They will ask questions about the definition of variance and what it measures.
