The Null Hypothesis assumes that there is no relationship or difference between the two samples or variables under investigation

what is meant by a directional (one-tailed) experimental hypothesis
For experimental designs: you predict a significant difference between variables A and B AND you predict that A will be larger/smaller than B

Explain how the t-value is calculated
Mean difference between conditions divided by the standard error of the mean difference between conditions
