1. Aphasia

   Annotations:

2. t-test

   Annotations:

   • 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

   Annotations:

   • 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)

5. Pearson's r

   Annotations:

   • Pearson r correlation is widely used in statistics to measure the degree of the relationship between linear related variables.
