Solutions for Session 10, Part A

See solutions for Problems: A1 | A2 | A3 | A4

Problem A1


The question the students are trying to answer is, "What is the relative frequency of each type of mint mark?"


The teacher brought a collection of nickels to the class so that students could examine the coins' mint marks.


The students organized their data into a circle graph.


The students are developing conjectures about the relative frequency of each mint mark.


The students are using their knowledge of fractions as they explore this problem. The investigation of mint marks involves connections to social studies.


Some statistical ideas are the nature of data, qualitative variables, variation, relative frequency, sampling, making a circle graph, and interpreting a circle graph.

Problem A2

The students are working with qualitative (categorical) data.

Problem A3

Answers will vary. One question might be, "Is this sample of nickels representative of the population of nickels?"

<< back to Problem A3


Problem 4

A circle graph is an appropriate way to display categorical data. Circle graphs show the fractional relationship of each category or part of data to the whole data set.
