## Chapter 2 - Day 9

##### Questions to Be Sure to Include
• MC question that require students to use the 68-95-99.7 rule.

• MC question that asks students to find the median and IQR from a cumulative relative frequency graph.

• MC question where a z-score is given and students have to work backwards to figure out an unknown mean or unknown standard deviation.

• MC question that asks students to interpret a z-score.

• Highest Priority: FR question that ask students to do normal distribution calculations.

• Area to the left

• Area to the right

• Find a value for a given area

• FR question that has a context that includes transformations of data (add/subtract and multiply/divide) and asks about center and variability.  You could also review Chapter 1 in this question by asking them to describe the distribution of the original data.

• FR question that asks students to identify the shape of a distribution of data based on the cumulative relative frequency graph.

• A question for assessing Normality is not high priority.

##### Tips to Give Your Students
• Close reading and careful writing are critical to your success this year.

• Be sure to answer all parts of each question.

• Normal distribution calculations are the single most important idea in Chapter 2.  Remind students that they need to draw and label a picture, show a formula and numbers, and be able to interpret the final answer.

• Know what happens to shape, center, and variability when data is transformed.

##### Activity: Normal Curve Calculations

A question that is assessing Normality can be very lengthy if they are checking using the 68-95-99.7 rule.  We don’t believe this to be a high priority.  We think it is a worthwhile activity in class, but not necessary for the test.
