Baddeley used a standarised procedure including standarised recorded/visual word lists. This allowed for replication of the study to retest the results which increases the reliability of the findings.
Explain one weakness of Baddeleys (1966b) study
Baddeley used a word list recall task as a test of memory processing. This lacks validity as it does not represent the way in which memory is used for day-to-day functioning.
Positive correlation : shows that as one variable increases the other variable increases
Negative correlations show that as one variable increases the other variable decreases
Explain one strength of the correlational research method
The correlation method allows researchers to investigate naturally occurring variables that may be unethical or impractical to test experimentally in a laboratory
Explain one weakness of the correlational research method :
The correlation method cannot establish a cause and effect relationship between variables, as there may be a lack of control over the other variables that may influence the outcome of the results being measured
