## Course Description

This course offers an introduction to quantitative analysis for anthropologists. The following topics will be discussed and practised in IBM SPSS Statistics:

• Introduction to descriptive statistics: variables and measurement level; univariate analyses; displaying distributions using graphs

• Discrete stochastic variables; expected value and variance; probability density function, distribution function

• Sample distributions for numbers and proportions

• Introduction to bivariate analysis

• Introduction to inferential statistics, Null Hypothesis Significance Testing

• Assessment of hypotheses; significance level, critical area, alpha and beta errors

• Statistical tests for correlation and for the comparison of group means

• Critique of Null Hypothesis Significance Testing

## Course Objectives

• Acquire knowledge of univariate analysis

• Learn to determine appropriate central tendency measures and variable distributions with SPSS and learn how to interpret them based on the research question and the level of measurement of the variables

• Acquire knowledge of bivariate analysis

• Learn to choose appropriate statistical tests for correlation and comparison of group means and learn to carry out the tests through SPSS, correctly report and interpret the outcomes based on the research question, the level of measurement, and the possible assumptions (parametric or non-parametric)

• Develop the capacity to reflect critically on Null Hypothesis Significance Testing and the role of statistics in scientific research and societal debates
