Also i put fMRI for the mpq as it has the best spatial resolution of the three and can study internal brain areas unlike ERP and EEG so is best for identifying an area.

What did people put for how the validity is affected by the researcher knowing which participants are in which group and how to fix this? Was it investigator effects?

For sign test you had to do condition B minus condition A and the total number of pluses was 3 which is the least frequent so it's the S value
They actually gave a different scenario the second time because this time they stated how the psychology teacher wanted to do the study of happiness with her students and used independent measures design and it was ordinal because its basically from scale of one to ten score your happiness.
But I could be wrong and don't worry about it now! Focus on paper 3 :smile:

was the sign test not 1 because the data on the table already calculated the difference?
Also why is it ordinal data when the same test tht was used used sign and so it mustve been nominal data?? so losttt

I wrote it increases researcher bias as the researcher influences the experiment....inorder to get the desired findings that he expects to get....

Lmao I put something like match on course studied, so they have similar stress/ workload. Stress can affect happiness levels
Dunno if it’s right but haha

for the neuron multiple choice it should've been relay motor relay because relay is found in the brain and spinal cord as they allow sensory and motor neurons to communicate.

also i put fMRI not ERPs because if u look in the text book fmri strength is that they provide a clear picture of how the brain is localised. whilst ERP's dont they show brain wave activity to specific stimuli

Did any other human on this planet put unrelated t test for the stats? It said score on a happiness questionnaire rather than a happiness rating, and as it’s a test score I thought it would be interval considering there are equal intervals? It’s probably wrong but thought I’d put it out there.
