• ### Overview

Course Description

This course is an introduction to descriptive and inferential statistics, which are useful for describing and analyzing data from a variety of fields. The topics covered include: analysis of univariate and bivariate data (including frequency distributions and graphs, measures of central tendency and variability, covariance and correlation), probability and random variables, sampling distributions, point and confidence interval estimation, and hypothesis testing (onesample and two-sample tests of hypothesis for means, variances and proportions, Wilcoxon signed-rank test, Wilcoxon-Mann-Whitney Test, and chi-square tests). The statistical package SPSS will be used in this course.

Course Goals

This course seeks to provide students with a better understanding of statistics in the context of applied research. In particular, this course aims to:

• Introduce students to statistical techniques of data analysis. • Increase students’ awareness of the applicability of these statistical techniques to reallife cases.

• Enable students to choose the most appropriate statistical method for a data analysis problem.

• Enable students to interpret and report the results of the statistical procedures covered in this course.

• Introduce students to the use of SPSS computer software for statistical analysis.
