Inferential statistics are concerned with making inferences based on relations found in the sample, to relations in the population. Inferential statistics help us decide, for example, whether the differences between groups that we see in our data are strong enough to provide support for our hypothesis that group differences exist in general, in the entire population.
We will start by considering the basic principles of significance testing: probability distributions, p-value, significance level, power and type I and type II errors. Then we will
consider a large number of statistical tests and techniques that help us make inferences for different types of data and different types of research designs. For each individual statistical test we will consider how it works, for what data and design it is appropriate and how results should be interpreted. You will also learn how to perform these tests using freely available software.
For those who are already familiar with statistical testing: We will look at z-tests for 1 and 2 proportions, McNemar's test for dependent proportions, t-tests for 1 mean (paired differences) and 2 means, the Chi-square test for independence, Fisher’s exact test, simple regression (linear, exponential en logistic) and multiple regression, one way and multi-way analysis of variance, and non-parametric tests (Wilcoxon, Kruskal-Wallis, sign test, signed-rank test).
Inferential statistics help us decide whether our data support our research hypothesis. In this course we will treat inferential statistics in detail. You will learn about the basics of significance testing and all the statistical tests that are typically treated in a full bachelor program in any quantitatively oriented social or behavioral science. If the terms below mean nothing to you, don't worry, they will all be explained!
You will learn when and how to use these statistical techniques, how to perform them using statistical software and how to interpret your own results and the results of others critically. We will also consider some questionable research practices (treated in the course Quantitative Research Methods) and see how statistics can be misused in more detail.
