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
2 of 14
Explain how the t-value is calculated
Mean difference between conditions divided by the standard error of the mean difference between conditions
3 of 14
How would you work out the proportion (or %) of variation that is shared between the two variables
R squared x 100

What is the conventional critical p-value for statistical significance?
p ≤ .05 [1 for the value, and 1 for the ‘≤’ sign
5 of 14
three measures of central tendency
Mean, median, Mode
6 of 14
Explain how the t-value is calculated
Mean difference between conditions divided by the standard error of the mean difference between conditions

What is qualitive psychology

What is triangulation
• Undertaking a second study with either a second group of participants [1] or using another method of data collection or having someone else collect or analyse the data would all provide triangulation and thus increase reliability of the findings.
