Unit description: In this unit the students will learn to gather and analyze data to make informed decisions, interpret variability and predict future outcomes based on data analysis.
Essential Outcomes of the Unit
Statistics and Probability
Investigate chance processes and develop, use, and evaluate probability models.
7.SP.8 Find probabilities of compound events using organized lists, sample space tables, tree diagrams, and simulation.
7.SP.8a Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.
7.SP.8b Represent sample spaces for compound events using methods such as organized lists, sample space tables, and tree diagrams. For an event described in everyday language, identify the outcomes in the sample space which compose the event.
7.SP.8c Design and use a simulation to generate frequencies for compound events.
Essential Questions and Big Ideas
How do you measure the probability of an event?
- You can use words such as unlikely and certain, or a number between 0 and 1 to represent the probability that an event will occur.
How do you measure the probability of more than one event?
- A compound event is an event associated with a multi-step action. You can find the number of outcomes of a multi-step process by finding the product of the number of possible outcomes of each step of the process.
Can you use probability to predict future events?
- You can perform trials and collect data to find experimental probability. You can reason about all of the possible outcomes of an event and find theoretical probability.
