Enduring Understandings
A survey is a data collection method that is administered to a sample. The sample is fraction of the target population. The sample must be representative of the population and random sampling is used to ensure an equal chance of being selected. A census is a special survey that collects data from the entire population. Sampling error and bias cause problems in analysis made from survey data.
Engagement
Students will view a video clip from the game show Family Feud to begin to think about survey
components. The video can be found at:

Learning Objectives
Statistical/Mathematical:
S-IC 1: Understand statistics as a process for making inferences about population parameters based on a random sample from that population.
S-IC 3: Recognize the purposes of and differences among sample surveys, experiments, and observational studies; explain how randomization relates to each.
S-IC 6: Evaluate reports based on data.
S-IC B.4 Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.
Data Science:
Understand that bias and sampling error should be minimized when conducting surveys. The wording of questions, as well as who is asked to participate in a survey, can lead to bias. Learn that sampling error can be minimized when larger random samples are collected from a population.
Applied Computational Thinking Using RStudio:
• Create random samples of different sizes to make estimates about a population.
• Create informal confidence intervals based on sample medians.
Language Objectives
-
Students will use complex sentences to construct summary statements about their understanding of data, how it is collected, how it is used, and how to work with it.
-
Students will engage in partner and whole group discussions and presentations to express their understanding of data science concepts.
-
Students will write questions that emphasize differences in data science concepts and skills.
