Modeling using functions:
Canadian household mobile subscription rates: trends, models and predictions
PROJECT OVERVIEW
Objective:
The objective of this project is to apply knowledge and understanding of fundamental characteristics of
basic functions and their transformations in order to create plausible models of data sets and study their
behaviour. Specifically, you will investigate the data compiled by Canadian Radio-television and
Telecommunications Commission on Canadian landline and mobile service subscribers per 100
households, with focus on households with a mobile subscription.
Project submission must be the result of individual work. Providing work to another person or using
someone else’s work, in part or in whole, is not allowed in this project. Questions and requests for
guidance may be made to the course instructor during office hours or by e-mail.
Deliverable: This document, completed in Microsoft Word format (Equation tool must be used for
mathematical expressions) with answers to questions provided sequentially as they are posed
throughout the Tasks list.
Submissions must demonstrate your
• understanding of major characteristics of basic functions and their transformations,
• application of mathematical analysis skills to create plausible models of data sets and study their
behavior, and
• employment of communication skills in support of choices, decisions and predictions
The product must demonstrate all tasks have been completed (see next section) and must include
answers to all questions posed within the tasks, justified fully using mathematical analysis techniques
(algebra, functions and calculus) and supported through visual representations (relevant data tables;
images of graphs created through Desmos).
Submission requirements:
• Submission must be in form of a single document in PDF format, stating clearly author’s student ID
number, last name and first name at the top of every page.
• The document must be submitted through Blackboard (see Course Content – Bonus Project) by
posted deadline.
IMPORTANT: Save your work and save it often. By registering with Desmos, you will be able to save
your work for later. If you prefer not to register, you can save your work by creating and saving a link to
the last state of your graph in Desmos through Share Graph tool.

TASKS
Sourcing the data
1. Retrieving the data
a. Using a web browser, locate the Canadian Radio-television and Telecommunications
Commission’s report on Communications Services in Canadian Households: Subscriptions and
Expenditures 2012-2016. Briefly (in one to three sentences) state what the report is about and
include the website address.
b. Read Quick Facts and briefly state what they say about trends in household communication
services subscriptions.
c. Read the summary on what communication services Canadian households use and briefly state
what additional trends are identified.
d. On the webpage, follow the link to the data source for the report (on Government of Canada -
Open Data) and briefly state the description of the data in the publication and the publisher of
the data.
e. State the licence under which the data is published, read its description and explain briefly why
you are allowed to use this data set for the project and any requirements related to use.
f. Download the XLSX file containing the data on Communications Services in Canadian
Households Subscriptions and Expenditures. Locate Table 1.1 and copy it into the document
here.
2. Understanding the data
a. Download the data dictionary (DOCX or TXT format) and read it.
b. Review the information in Table 1.1 and explain what the data is describing.
c. What are the input values and the output values, and their units of measurement?
