Course Description
This course introduces students to the concepts and applications of statistics and focuses on the analysis and interpretation of data from experiments and surveys using descriptive and inferential statistics. Computerized data analysis is also introduced.

1. Abuses of statistics
2. Organizing and describing data
3. Measures of central tendency
4. Measures of variability
5. Description of frequency distributions
6. Properties of normal distributions
7. Central Limit Theorem
8. Introduction to probability concepts
9. Hypothesis testing
10. Analysis of Variance
11. t-tests
12. Correlation methods
13. Regression and prediction
14. Nonparametric statistical methods
15. Statistical significance versus practical importance
Learning Outcomes

At the conclusion of the course the successful student will be able to:

1.  Distinguish between descriptive and inferential statistics.
2. Define various key statistical terms, such as population, sample, parameter, variable, random sample, sampling distribution, level of significance, critical value, Type I and Type II errors, and the null hypothesis.
3. Define and describe various measures of central tendency.
4. Explain the concept of variability.
5. Calculate various statistics such as standard deviation, variance, z scores correlation coefficient (r), t-test, analysis of variance, chi square.
6. Distinguish between correlation and causation.
7. Explain the meaning and use of the regression equation.
8. Compute regression coefficients and fit a regression line to a set of data.
9. Distinguish between a theoretical and empirical distribution.
10. List the characteristics of the normal distribution.
11. Calculate confidence intervals about a sample mean and explain what they mean.
12. Explain the logic of inferential statistics.
13. Describe the factors that affect rejection of the null hypothesis.
14. Distinguish an independent-samples design from a correlated samples design.
15. List and explain the assumptions for the t-test and ANOVA.
16. Identify the independent and dependent variables in a one-way ANOVA and a two-way ANOVA.
17. Explain the rationale of ANOVA.
18. Define F and explain its relationship to t.
19. Compute sums of squares, mean squares, degrees of freedom, and F for an ANOVA.
20. Interpret an F value obtained in an experiment.
21. Construct a summary table of ANOVA results.
22. Distinguish between a priori and a posteriori tests.
23. Identify the sources of variance in a factorial design.
24. Compute F values and test their significance in a factorial design.
25. Interpret main effects and interactions.
Means of Assessment

Evaluation will be carried out in accordance with Douglas College policy.  Evaluation will be based on course objectives and will include some of the following: quizzes, multiple choice exams, essay type exams, term paper or research project, computer based assignments, etc.  The instructor will provide the students with a course outline listing the criteria for course evaluation.

An example of one evaluation scheme:

 12 quizzes 50% Computer based homework assignments 10% Homework exercises 10% Term project paper 20% Final exam 10% Total 100%
