Statistics and Probability
Use random sampling to draw inferences about a population. (7.SP.1-2)
Find probabilities of simple and compound events. (7.SP.8)
Concepts and Skills
* Understand meaning and value of random sampling
* Use samples to draw inferences
Compare two data distributions
Use measures of center and measures of variability to draw inferences about two populations
* Identify probability as a number between 0 and 1
* Utilize experimental and theoretical probability models
* Find probabilities of compound events
A student in 7th grade can demonstrate the ability to apply and comprehend critical language by investigating situations to find probabilities, and interpreting results and analyzing data.
Measures of center
Measures of variability
Data collection and analysis allows us to make more accurate inferences and predictions.
Factual Guiding Questions

What are different types of sampling methods?
Conceptual Guiding Questions
How can probabilities be used to make decisions about situations?
How can you compare two data distributions?
How do you use samples to draw inferences?
How can experimental and theoretical probabilities be used to determine if a game is fair?
How do the experimental and theoretical probabilities compare when you increase the number of trials in a game?
Based on the data, what do you predict/infer about this population?
Engaging/Debatable Guiding Questions
Which method would you use to find the theoretical probability for a given situation?
Which measure of center is appropriate for a given situation?
Were the ways in which the data were collected or analyzed likely to give results that represent the population? Why or why not?
