Lecture week 9- para and non-para tests Flashcards
what are all statistical tests derived on the basis of
what tests relate to normally distributed data
what shapes are parametric tests
what are the calculations based on for parametric tests
what tests relate to not normally distributed data
what shape are non-parametric tests
what are the calculations based on for non- parametric tests
median and IQR
What type of data is nonparametric
If data are not normally distributed can you mathematically transform it
what are 4 examples of transformations
does transforming data always normalise data
what are the 4 consequences of transforming data
What are the differences between parametric and non-parametric tests?
what type of data relates to parametric tests
does non-parametric tests put data in ranks
how do we rank data from non-parametric tests
what are the pros of non-parametric tests
what are the cons of non-parametric tests
what is the parametric and non test for paired samples
what is the parametric and non test for 2 independent groups
what is the parametric and non test for over 2 independent groups
what is the parametric and non test for correlations
what is the parametric and non test for categorical/ nominal/ ordinal data
what is the wilcoxon signed rank test
what is an example of a wilcoxon signed rank test
What is the Mann Whitney U test?
What is an example of the Mann Whitney U test?
What is the Kruskal-Wallis Test?
What is an example of the Kruskal-Wallis Test
What is the Chi-square test X2
What is an example of the Chi-square test?
what is a low SES associated with
