MATH 170 Syllabus

Applied Statistics

Revised: August 2018

Course Description

Descriptive statistics, exploratory data analysis, probability distributions, correlation, regression, estimation, and hypothesis testing. Three semester hours.

Student Learning Objectives

By the end of the course, students should be able to:

   1. Describe the concepts of population and sample, and some of the basic descriptive measures associated with them.
   2. Explain and utilize graphical methods for data presentation.
   3. Connect the concepts of probability, random variables, and distributions.
   4. Assess the properties of common distributions, especially the normal and binomial.
   5. Synthesize the ideas of correlation and regression.
   6. Interpret estimation and hypothesis testing procedures applied to population means and proportions.

Learning Objectives for Liberal Studies

This course satisfies the C2 Core requirement for the Liberal Studies Program.  This course satisfies the Liberal Studies Mathematics course criteria of providing an introduction to applications of mathematics to daily experience.  Emphasis will be on the development of conceptual understanding rather than on computational drill.  The revised objectives and outcomes of the Liberal Studies Program addressed by this course include:

Objective: Information Literacy

Outcome #2: Students will identify appropriate information sources and evaluate critically the credibility of those sources for relevance, legitimacy, and bias.

Objective: Critical Thinking

Outcome #3:  Students will evaluate evidence, context, and multiple perspectives as a means of analyzing complex issues.

Objective: Problem Solving

Outcome #4 Students will apply appropriate disciplinary methodologies to answer questions and propose solutions to problems within the human and natural worlds.
