How to Make Seeds for Essay
Probability and Statistics
Unit Overview
In this unit you will investigate independent and dependent probabilistic situations and compare theoretical and experimental probability. You will practice displaying, summarizing, interpreting, and communicating univariate and bivariate data.

Essential Questions
? ?
How do different displays help you interpret data?
Academic Vocabulary
Add these words to your vocabulary notebook. categorical variables range experimental probability simple random sample (SRS) numerical data outlier theoretical probability
Why is it important to know if events are dependent or independent when calculating probabilities?
EMBEDDED ASSESSMENTS
This unit has two Embedded Assessments, after Activity 5.2 and 5.4. These embedded assessments allow you to demonstrate your understanding of probability, box plots, finding the mean, data displays, and random samples.
