Product Description
This is an assessment that can be used pre/post for Statistics and Probability Standard:

7.SP Use random sampling to draw inferences about a population. 1. Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.2. Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions.
7.SP Draw informal comparative inferences about two populations. 3. Informally assess the degree of visual overlap of two numerical data distributions with similar variability, measuring the difference between the centers by expressing it as a multiple of a measure of variability. 4. Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.

Students will:
1)Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the even occurring.
2) Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.
3) Approximate the probability of a chance even by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability.
