2. Use measures of variation to interpret and compare data.
3. Display and interpret data in a histogram.
4. Interpret data in a histogram.
5. Select an appropriate display for a set of data.
6. Find the probability of simple events.
7. Use a sample to predict the actions of a larger group.
8. Use tree diagrams or the Fundamental Counting Principle to count outcomes and find the probability of events.
Objective used to evaluate students
Yes
Assessment Activity
Students will be assessed by:
1. Using the Measures of Variation worksheet to show the students can find measures of variation and use measures of variation to interpret and compare data.
2. Using the Histograms worksheet to show the students can display and interpret data in a histogram and interpret data in a histogram.
3. Using the Selecting an Appropriate Display worksheet to show the students can select an appropriate display for a set of data.
4. Using the Simple Probability worksheet to show that students can find the probability of simple events and use a sample to predict the actions of a larger group.
5. Using the Counting Outcomes worksheet to show the students can use tree diagrams or the Fundamental Counting Principle to count outcomes and find the probability of events.
