# Mathematics (MATH) 215

## Introduction to Statistics (Revision 10)

Mathematics Diagnostic Assessment. This online test contains 70 questions that will help you assess your mathematical skills. Based on your score we will recommend which Athabasca University mathematics course you are likely ready to take successfully.

Delivery Mode: Individualized study online with eText or Grouped Study

Credits: 3

Area of Study: Science

Prerequisite: None. However, fundamental mathematical skills are required, particularly the ability to do algebra. Textbooks on basic mathematics are available at the Athabasca University Library. AU Math Centre (an upgrading tutorial site) is suitable preparation for taking MATH 215, for those students concerned about their mathematical background.

Precluded Course: MGSC 301 and MATH 216 (MATH 215 may not be taken for credit if credit has already been obtained for MGSC 301 or MATH 216.)

Faculty: Faculty of Science & Technology

Centre: Centre for Science

MATH 215 has a Challenge for Credit option.

## Overview

MATH 215 gives students a working knowledge and understanding of descriptive and inferential statistics and how statistics is applied in the sciences, social sciences, and business.

## Learning Outcomes

After completing this course, you should be able to

1. organize, summarize, and display data in a meaningful way.
2. compute various measures of centre, variability and position of data sets.
3. apply basic rules of probability to calculate likelihoods of random events.
4. use appropriate probability distributions to estimate and test hypotheses about parameters of single and multiple populations.
5. perform goodness-of-fit tests and analyse cross-tabulated data.
6. use linear correlation and regression methods to analyse relationships in bivariate data.

## Outline

• Unit 1: Descriptive Statistics
• Unit 2: Probability
• Unit 3: Probability Distributions
• Unit 4: Estimation and Tests of Hypotheses for One Population
• Unit 5: Tests of Hypotheses for Two or More Populations
• Unit 6: Bivariate Analysis

## Evaluation

To receive credit for MATH 215, you must achieve a mark of at least 50 per cent on each of the following: the midterm examination, the final examination and achieve a composite course grade of at least D (50 percent). The weighting of the composite grade is as follows:

Activity Weighting
6 Assignments (3 1/3% each) 20%
Midterm Exam 40%
Final Exam 40%
Total 100%

Both the midterm and final are closed-book, short-answer, machine-marked exams in the Möbius online platform and are invigilated through ProctorU. You will have three (3) hours to complete each exam.

Students requiring special accommodations should contact Accessibility Services.

## Course Materials

### eText

Registration in this course includes an electronic textbook. For more information on electronic textbooks, please refer to our eText Initiative site.

Mann, Prem S. Introductory Statistics, 9th ed., NJ: Wiley, 2016.

WileyPLUS Interactive Textbook to complement Introductory Statistics, containing tutorials, additional practice, and solutions to odd-numbered exercises.

A print version of the eText can be purchased from the publisher through a direct-to-student link provided in the course website; you can also acquire the textbooks on your own if you wish.

Note: The eText may be downloaded on your device with an option to print its content. If you desire a hard copy of the text, you may order one at a discounted price from the Direct-to-Student (DTS) site for Athabasca students.

### Special Course Features

Please note that the Texas Instruments TI-30Xa Scientific Calculator is the only calculator that you are permitted to use on a MATH 215 exam.

## Challenge for Credit Overview

The Challenge for Credit process allows you to demonstrate that you have acquired a command of the general subject matter, knowledge, intellectual and/or other skills that would normally be found in a university-level course.

Full information about Challenge for Credit can be found in the Undergraduate Calendar.

## Challenge Evaluation

To receive credit for the MATH 215 challenge registration, you must complete the two parts of the challenge exam and achieve a minimum grade of at least D (50 percent) on Part II and a course composite grade of at least D (50 percent). The two parts of the exam must be written either on the same day, or on two consecutive days.

Activity Weighting
Part 1: Exam 50%
Part 2: Exam 50%
Total 100%
