3 What is the difference between intra rater and inter rater relibility 

i.             Carry out a rank order correlation of the first and second sets of marks. 
       This is to check ‘intra-rater reliability’.



  1. i.          Intra-rater reliability

2nd time
d = R1-R2

ii.            Correlate the first set of marks with another person’s first set of marks. 
       This is to check ‘inter-rater reliability’.


  1. ii.        Inter-rater reliability

Factors That Can Affect The Inter-rater Reliability

There are several factors that can affect inter-rater reliability

  • Knowledge background.

v  Markers’ knowledge background is somehow a factor that can alter the reliability for marking process. It is because their views on certain issues may vary, thus affecting their agreement on the issues. This may lead to differences in evaluation during the marking.

  • Markers’ experience in marking.

v  A group of markers’ with distinct differences in experiences may lead to disagreement among them. Experience may alter their perceptions towards candidates’ performances, thus becoming a major factor that can affect the inter-rater reliability.

Experimental design



I need to find more on:

1. Repeated measures experimental design /
This type of design is also known as within groups
https://www.simplypsychology.org/experimental-designs.html

2. ANOVA and repeated measures

3. Counterbalance methods

4, Recommended effect size statistics
for repeated measures designs.
