Brief discussion of Canonical analysis and Discriminant analysis INFORMATION ABOUT THE CLASS: Course Description: The purpose of this course is to develop an understanding of the fundamental concepts of descriptive and inferential statistics as applied in educational research. The course activities will focus on helping students to interpret data and understanding of proper application of statistical techniques in the field of education. A weekly Lab is a part of the course. The lab provides opportunities for students to practice and improve their skills in analyzing and interpreting data applying SPSS for Windows. The students are encouraged to use lab time to work on their lab work and Homework. Prerequisite: Y520 or equivalent course has been taken and passed by a student. The working knowledge of arithmetic and basic algebra is essential to understand the course content of Y502. Assessment of students' performance: Assignments (15% of final grade): (1)Lab and homework assignments (all lab & homework must be turned in by due dates to receive full credit). (2) Assigned readings: Two articles from professional journals. One written project (10% of final grade) Examinations: There will be three (3) exams (each 25% of final grade). Materials: Please bring the textbook, handouts, notes, graph papers, a calculator and a ruler to class. TEXT BOOK: Hinkle,D.E., Wiersma, W., Jurs, S.G., (1998).
