Intro to the Chi-Squared Unit

Unit Essential Question:

How do we statistically tell the difference between two populations given one metric?

Enduring Understandings:

The greater the sample size the more accurate the statistics of that population are.
Statistics use probability as a way to justify conclusions on a population.
The higher the probability or p-value, the more statistically significant the statistics are.

Objectives:

Identify a valid sampling method
Determine the population for which conclusion of a sample are valid
Use random samples to make estimates
