III-a Introduction to Quantitative Data Analysis

Description of workshop contents

This workshop focuses on the use of probability sampling, quantitative analysis and data visualization to improve the quality and efficiency of development evaluations. On one hand, quantitative data analysis provided policy makers with quantifiable and easy to understand results. On the other hand, probability sampling help policy makers to generalize their results to the population of interest. Hence, both of these give policy makers the objective evidences to generate or inform policy at regional or national level.

This workshop introduces participants to the basics of descriptive as well as of inferential statistics. The discussion includes, measurement scales, measure of central tendency, measure of variability, confidence interval, simple linear correlation, and contingency tables.

The workshop also helps participants understand how to use the various probability sampling strategies. Topics include, simple random sampling, systematic sampling, stratified sampling, PPS sampling, multi-stage sampling, etc.… Participants practice skills throughout the workshop using Excel and web-based tools, as well as working in small groups.
