This week’s lessons are about conducting surveys, experiments, and observational studies, as well as frequency distributions, weighted averages, and expected values.
Each lesson has an answer sheet that provides guidance on the lesson and describes its key concept and questions. Use this sheet to check your answers.
The student sheet can be printed and completed by the student, or the student can write their answers on a blank sheet of paper.

Activity 1: Surveys
For any large population, it is usually impractical to conduct a census. Instead, statisticians often rely on surveying a sample of the population. If the sample is well chosen and the survey is free of bias, the results of the survey can be used to make a prediction about the population.
Use this lesson to learn how to analyze a survey, how to use a survey to make a prediction, and how to interpret the margin of error of a survey.
