Course Description This course is designed to develop a working understanding of the fundamental concepts used in descriptive and inferential statistics. The purpose is to understand the use of statistics in educational research as a tool to analyze and interpret data. To this aim the course activities will focus on generating and interpreting sample statistics. The course also includes a weekly lab which will provide opportunities for students to practice analyzing and interpreting data using SPSS for Windows. The lab is designed to assist students working on the assigned labwork and homework. Prerequisite: Y520 or equivalent. Students are also expected to have a working knowledge of arithmetic and basic algebra. Course Requirements and Assignments Students are responsible for the assigned readings and for in- class/lab and homework assignments. Please bring the book, handouts, notes and a calculator to class. In addition there will be three exams (each 25 % of final grade) and one written project (25% of final grade) which will require analysis and interpretation of a data set. Assigned labwork and homework is required—it will not be graded but will be checked for completion, adequacy and accuracy. To receive full credit all homework assignments have to be completed and turned in on time. If homework is not turned in or is systematically late, incomplete or inadequate your final grade will be decreased by one grade level or two (e.g., A will turn into A- or B+) depending on the number of late and incomplete assignments. A course grade of “Incomplete” will not be assigned except in the case of illness or other emergencies. Intended or unintended cheating and/or plagiarism (see academic handbook) will yield an F in the course. Reading Harris M. B. (1998). Basic Statistics for Behavioral Science Research.
