Course Syllabus

Abstract

The course aims to provide students with understanding of key concepts and methods of modern statistical data analysis. It gives an overview and practice of the skills necessary for conducting independent research with quantitative survey data, using R software. The course also puts these skills into the broader academic context by reviewing how statistics are used in published scientific journal articles.

Course Contents

  • Statistical inference in social sciences
    Descriptive and inferential statistics. Random and non-random sampling, the case of “Literary Digest”. Normal distribution and z scores. The logic of statistical inference and Central limit theorem. Confidence level and confidence intervals.
  • T-tests, One-way ANOVA
    Steps of hypothesis testing, Two-tailed/one tailed assumptions, Type I/Type II errors. One sample t-test. Independent samples test, paired samples test. T-distribution for small samples. ANOVA (Analysis of variance), F-distribution, post hoc tests. Equality of variance tests and tests for normal distribution.
  • Non-parametric analogues of T-tests and one-way ANOVA
    Differences between parametric and non-parametric methods. Signed-Rank Test, Mann-Whitney U-test, Wilcoxon signed rank test, Kruskal-Wallis test, post hoc tests for non-parametric methods.
  • Pearson's chi-square for contingency tables
    Properties of Pearson's chi-square, independence of two variables, expected and observed frequencies. Chi-square distribution, Yates correction for 2x2 tables. Limitations of the chi-square test.
  • Correlations
    Association between two variables, types of dependence. Pearson`s r for metric scales, Pearson`s R for metric scales and test of significance. Spearman`s rank correlation coefficient, Kendall`s rank correlation coefficient. Partial correlation.
  • Linear regression
