    #22 Multidimensional Scaling
    Dec 2 2020
    Multidimensional scaling is a statistical procedure to translate distances and dissimilarities into a visual representation. In social science it is used to visualize social relations among people and groups.

    #20 Factor Analysis
    Dec 2 2020
    Factor analysis reduces complexity of data by extracting a few factors. It delivers underlying coordinates in an otherwise complicated set of variables. We use factor analysis for instance to understand the basic independent dimensions of personality.

    #19 Variance Analysis
    Dec 1 2020
    We use variance analysis (ANOVA) to compare variance within and between groups. It is a method to test hypothesis that is in particular suitable for experimental designs. Once there are more than one independent variables we name this MANOVA.

  • #18 Hypothesis Testing

    #18 Hypothesis Testing
    Dec 1 2020
    In social science we estimate the probability of the null hypothesis being wrong even though it might be true. Should we reject or accept the null hypothesis over the alternative hypothesis? This is an essential idea in inferential statistics. All slides to the entire series can be downloaded for free here: https://armintrost.de/en/professor/digital/social-research-methods/

    #16 Estimating Mean and Standard Deviation of Population
    Dec 1 2020
    While we know the mean and standard deviation of our sample we don’t know the real ones. That’s why we estimate. There is a reason, why using n-1 instead of N when estimating standard deviation of the population based on a sample.
