    • A box plot (also called a box and whisker diagram) is a simple visual representation of key features of a univariate sample.

  • Multivariate Testing

    • Because measures of this type are usually highly correlated, it is not advisable to conduct separate univariate $t$-tests to test hypotheses, as these would neglect the covariance among measures and inflate the chance of falsely rejecting at least one hypothesis (type I error).
    • In particular, the distribution arises in multivariate statistics in undertaking tests of the differences between the (multivariate) means of different populations, where tests for univariate problems would make use of a $t$-test.

  • Introduction to describing one network

    • Most social scientists have a reasonable working knowledge of basic univariate and bivariate descriptive and inferential statistics.
    • So, let's begin with the simplest univariate descriptive and inferential statistics, and then move on to somewhat more complicated problems.

  • Repeated Measures Design

    • Univariate assumptions include:
    • Standard Univariate ANOVA $F$-test: This test is commonly used when there are only two levels of the within-subjects factor.
    • Alternative Univariate test: These tests account for violations to the assumption of sphericity, and can be used when the within-subjects factor exceeds 2 levels.
    • The $F$ statistic will be the same as in the Standard Univariate ANOVA F test, but is associated with a more accurate $p$-value.

  • Probability

    • A probability density function is most commonly associated with absolutely continuous univariate distributions.
