Methods Of Instruction

This course will employ a number of instructional methods to accomplish its objectives and will include some of the following:

• lectures
• audio visual materials
• small group discussion
• research projects
• computer based tutorial exercises
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.
Course Content
1. Abuses of statistics
2. Organizing and describing data
3. Measures of central tendency
4. Measures of variability
5. Standard scores
6. Description of frequency distributions
7. Properties of normal distributions
8. Central Limit Theorem
9. Introduction to probability concepts
10. Null hypothesis significance testing
11. Analysis of Variance and t-tests
12. Correlation methods
13. Regression and prediction
14. Nonparametric statistical methods
15. Statistical significance versus practical importance
16. Measures of effect size and confidence intervals
Learning Outcomes

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

1. Define, describe and distinguish between descriptive and inferential statistics, and identify in what contexts each is appropriate.
2. Define, describe, distinguish between, and demonstrate ability to calculate, by hand and/or using statistical software, various key descriptive statistical terms, such as: empirical distribution, frequency distribution, histogram, percentile, quartile, measures of central tendency (median, mode, mean), sum of squares, measures of variance (range, variance, standard deviation, within-groups variance, between-groups variance), standard score/z-scores, covariance, Pearson r, regression coefficient, model, and effect size (e.g., Cohen’s d, Eta squared).
3. Define, describe, distinguish between, and demonstrate ability to calculate, by hand and/or using statistical software, various key research designs and inferential statistical terms, such as: scales of variables (nominal, ordinal, interval, ratio),  independent variable (IV), dependent variable (DV), theoretical distribution, population, sample, statistic, random sampling, estimator, estimate, probability distribution, parameter, normal distribution, t distribution, F-distribution, Chi-square distribution, sampling distribution, null hypothesis significance testing (NHST), null hypothesis, alternative hypothesis, p-value, alpha, beta, power, type 1 error, type 2 error, critical value, statistical significance, and confidence interval.
4. Describe and explain the logic of inferential statistics. This includes being able to explain what a p-value is, what statistical significance means, and how various factors, such as sample size, effect size, alpha and violation of assumptions, influence the p-value and statistical significance.
5. Calculate, interpret, explain the rationale for, and analyze the assumptions for appropriate test statistics and p-values for situations such as the following: a) there is one IV that has two or more levels and the DV is a scale variable – the IV may be a between or within subjects IV, b) there may be a linear relationship between two variables and the null hypothesis is that the population relationship is 0, c) there are observed frequencies for one or two variables and the null hypothesis is that the distribution of observed frequencies is non-proportional.
6. Interpret basic research results as published in academic journals.
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 40% Computer based homework assignments 10% Homework exercises 10% Midterm exam 20% Final exam 20% Total 100%
