1. Aphasia

   Anmerkungen:

   • Acquired neurogenic language disorder (injury to the brain) that affects all language modalities: spoken language expression, spoken language comprehension, written expression, and reading comprehension.

         Anmerkungen:

         • Internal validity refers to how well an experiment is done, especially whether it avoids confounding (more than one possible independent variable [cause] acting at the same time). The less chance for confounding in a study, the higher its internal validity is.
      2. External Vallidity

         Anmerkungen:

         • the extent to which the results of a study can be generalized to other situations and to other people.
   5. Participation Bias

      Anmerkungen:

1. Chi-squared

   Anmerkungen:

   • used with categorical data to see whether any difference in frequencies between your sets of results is due to chance
2. t-test

   Anmerkungen:

   • enables you to see whether two samples are different when you have data that are continuous and normally distributed. The test allows you to compare the means and standard deviations of the two groups to see whether there is a statistically significant difference between them.
3. Mann-Whitney U-test

   Anmerkungen:

   • It is used when comparing ordinal data (i.e. data that can be ranked or has some sort of rating scale) that are not normally distributed. Measurements must be categorical – for instance, yes or no – and independent of each other (e.g. a single person cannot be represented twice)
4. Spearman's Rho

   Anmerkungen:

   • tests the relationship between two variables in a dataset. If there is a statistically significant relationship, you can reject the null hypothesis, which may be that there is no link between the two variables.
   • NONPARAMETRIC
5. Pearson's r

   Anmerkungen:

   • Pearson r correlation is widely used in statistics to measure the degree of the relationship between linear related variables. 
   • For the Pearson r correlation, both variables should be normally distributed.  Other assumptions include linearity and homoscedasticity
6. ANOVA

   Anmerkungen:

   • tests for the difference in means between two or more groups
   1. MANOVA

      Anmerkungen:

      • Multivariate analysis of variance (MANOVA) is simply an ANOVA with several dependent variables, tests for the difference in two or more vectors of means.
