The Cost of Car Insurance Teacher Notes

Topic: Data Analysis and Probability

NCTM Standard(s)

• For univariate measurement data, be able to display the distribution,

describe its shape, and select and calculate summary statistics.

Objective:

Given a set of data, the student will be able to enter data into the statistics

menu of the Casio 9750 GII, graph the data using a median box-and-whisker

graph, and calculate the measures of central tendency.

Getting Started

Have the students work in pairs or small groups and come up with examples

of using one-variable data, what kind of information can be obtained from

one-variable data and what types of graphs can be used to represent one-

variable data.

Prior to using this activity:

• The student should be able to calculate basic statistics.

• The students should be familiar with interquartile values.

Ways students can provide evidence of learning:

• Given a set of data, the student should be able to create a box and whisker

plot.

• The student should be able to answer questions about the range of a set of

data.

Common mistakes to be on the lookout for:

• Students may pick a measure of central tendency that does not best

describe the situation.

• Students may not understand the effect that outliers have on the set of

data.

Definitions:

• Mean

• Median

• Mode

• Standard Deviation

• Interquartile Range

• Central tendency
