Course Description
Addendum to Course Description
This class is not intended to be a study hall for students to work on STAT assignments. The time needs to be spent working on material designated by your ALM instructor. If a student is coenrolled in a STAT class, then this may include targeted materials which are intended to support the concepts being taught in that STAT class.
Intended Outcomes for the course
Upon completion of the course students should be able to:

Perform appropriate statistical and/or mathematical computations for a variety of situations either by hand or using an approved technology.

Apply statistical problem solving strategies in limited contexts.

Address statistical problems with increased confidence.

Demonstrate progression through learning objectives established between the student and instructor.
Course Activities and Design
Instructors may employ the use of worksheets, textbooks, online software, minilectures, and/or group work.
Outcome Assessment Strategies
Assessment shall include at least two of the following measures:
1. Active participation/effort
2. Personal program/portfolios
3. Individual student conference
4. Assignments
5. Pre/post evaluations
6. Tests/Quizzes
Course Content (Themes, Concepts, Issues and Skills)
Items from the course content may be chosen as appropriate for each student and some students may even work on content from other ALM courses as deemed appropriate by the instructor.
Statistics I (STAT 243) – (Taken from the STAT 243Z CCOG)
Course Content (Themes, Concepts, Issues and Skills)
 Identify and describe common statistical terminology: descriptive statistics, inferential statistics, population, sample, variable, observational units, statistic, parameter, quantitative (numerical) data, qualitative (categorical) data, observational study, experiment

ALM ADDENDUM:
The mission of the MTH/STAT ALM is to promote student success in MTH/STAT courses by tailoring the coursework to meet individual student needs.
Specifically, the ALM course:

supports students concurrently enrolled in MTH/STAT courses;

prepares students to take a MTH/STAT course the following term;

allows students to work through the content of a MTH/STAT course over multiple terms;
