Practise distinguishing quantitative and qualitative evidence, selecting data that fits the aim and explaining consequences for analysis, depth and interpretation.
Dement and Kleitman (sleep and dreams) asked participants to record their dream narratives. The words in each narrative were counted.
Identify the type of data provided by counting the words in the narratives. Justify your answer.
Quantitative; because it was the number of words/was numerical/ how many...; (justification)
2
type of data (quantitative) = 1 [definitive] justification = 1 (does not have to be linked)
lgnore discrete / categorical = 0= incorrect Accept ordinal/interval/ratio
Explain one strength of collecting this type of data in this study.
Explain one strength of collecting this type of data in this study.
can be analysed / compared; (explanation) can use statistics/graphs; (explanation) e.g. compare number of words in REM and nREM; (link)
objective / does not need interpretation / free of bias; (explanation) dream 'detail' less reliable to estimate; (link)
numerical is reliable; (explanation) researchers are unlikely to make mistakes counting words; (link)s

explanation = 1
link = 1
factual / accurate =0
measurable =0 needs 'because' or 'than'
