O. Adejumo/Mr. D. O. Igbokwe [email protected] A. Course Description The course requires the students to appreciate the greater need for statistical techniques as they are required even at higher levels. Topics to be covered include scales of measurement, concept of hypothesis testing, univerate analysis statistical tools and difference between parametric and nonparametric statistical tools. Some examples of parametric and nonparametric statistical tools will be examined. B. Rationale This course discusses the concept of hypothesis testing. The application of parametric test for one sample, independent and dependent samples C. Course Objectives By the end of this course, students should be able to; 1. Explain the concepts related to hypothesis testing. 2. Calculate and interpret t-test and correlation coefficients D. Methods of Course Delivery Methods of instruction may include, but not limited to the following: 1. Lecture and accompanying supplements like projector, video compact player 2. Classroom discussion E. 1. 2. 3. 4. 5. 6. Grand Rules No student will be allowed into class after fifteen (15) minutes of lectures. Students are expected to maintain proper classroom etiquette. Eating and/or drinking are not permitted in class. Assignments and term papers are expected to be submitted at the appropriate time. Plagiarism and other academic dishonesty will not be tolerated. Students MUST have a 75% class attendance to qualify for examinations. F. Evaluation Plan The grading process shall consist of: Continuous Assessment = 30% Semester Examination = 70% The continuous assessment shall be based on a combination of class tests, quizzes, assignments, term papers and the Mid-semester examinations. G. Course Modules Module 1 Overview of the course Week 1 Introduction – review of the last sessions’ work Module 2 Theoretical Concepts related to hypothesis testing Week 2-3 One –Tailed versus Two Tailed Tests , The Alpha Error probability The Alpha Error Probability Power and the Beta Error Probability Effect Size Total Sample Size The Ratioq:=b/a The Noncentrality Parameter Critical Value A Relation among Sample Size Effect Size and Noncentrality parameters Module 3 Parametric test Week 4 One-sample t-test Week 5 t-test for Dependent samples test. Week 6 Mid-semester examination Week 7 t-test for the Significance of the Difference between the Means of Two Independent Samples Week 8 Correlation key concepts-deviations, covariance, standardization , Correlation ratio, etc) Types of Correlation and when to use them Week 9 Pearson's r: / product-moment correlation Module 4 Introduction to non-parametric test Week 10-11 Introduction and list of non-parametric tests and when to use them Non Parametric test for two conditions A. Wilcoxon test [Related] B. Mann-Whitney U test [Unrelated] Week 12-13: Non-Parametric test for three or more conditions A. Friedman test [Related] B. Kruskal-Wallis H test [Unrelated] Week 14 Revision Week 15 Examinations H. Topics for Term Paper, Assignment, Project etc 1. What is hypothesis testing? 2. Identify steps in hypothesis testing 3. Write short notes on the following a) b) c) d) e) I. One –Tailed versus Two Tailed Tests , The Alpha Error probability The Alpha Error Probability Power and the Beta Error Probability Effect Size Core Value Emphasis The core values of integrity, responsibility, diligence, possibility mentality and capacity building were emphasized in this course, as they aim at driving students towards objectivity and hard work. This course deemphasizes subjectivity and inculcates a sense of possibility in students. J. Industry Relevance The importance of this course is highly visible as regards industries and organizations because statistics is an integral part of the research procedures in psychology and other endeavours.
