ECN 132 Course Outline

This document outlines an introductory statistics course offered at the University of Lagos. The course objectives are to explain the role of statistics in social science research, distinguish between populations and samples, present data in different forms, and calculate measures of central tendency and dispersion. The course outline covers topics such as frequency distributions, measures of central tendency including the mean, median and mode, measures of dispersion like the standard deviation and variance, and applying these statistical concepts in economics. Suggested reading texts are also provided.
