Week 12 Flashcards
How can you be sure an effect does exist?
Reproducible
What is replication important for?
Reproducibility; helps you accumulate more evidence
What is the file drawer problem?
Too much research is ‘filed away’ in favour of positive findings
What is p-hacking?
When you keep analysing your results until you find a significant effect.
What are some examples of Questionable Research Practices?
P-hacking; excluding data without justification; measuring multiple DVs but only reporting a subset; controlling multiple IVs but only reporting a subset.
What are the different kinds of replication?
Direct, conceptual, replication plus extension, independent replication
What is direct replication?
Boring kind of replication - same stimuli, design and kind of participants used.
What is conceptual replication?
Uses different operational definition of the relevant variables, different sample, different design.
What is replication plus extension?
Like a direct replication where the effect of interest is reproduced but further expansions and developments are added.
What is independent replication?
Completely independent set of researchers replicate the effect of interest with possible different design, instrument, stimuli, participants.
What are meta-analyses?
Grouping the results of several experiments and finding a overall average.
