2. I can determine the different sampling techniques used in real life.
How can random samples be used to make predictions about populations?
How are proportions used to estimate information about populations?
How do I determine an appropriate sample size?

3. I can determine the different sampling techniques used in real life.

4. MGSE7.SP.3/MGSE7.SP.4: I can use measure of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.

5. Average
