Quantitative and Qualitative data Flashcards
(22 cards)
What is quantitative data?
data that is expressed numerically and statistically.
Can use this data for stats tests
Where do we get quantitative data?
typically controlled studies like Lab experiments
What questions gather quantitative data?
closed questions
What is an example of quantitative data?
a memory experiment and recalling how many words were recalled, such as Baddeley
What is a strength of quantitative data giving analytical, statistical data?
it assesses whether results are significant or due to chance.
Why is it a strength that quantitative data can be easily anaylsed?
data can be represented in charts and graphs giving objective results.
Why is it a strength that quantitative data uses operationalised variables?
It makes the study easier to repeat to test for reliability
Why is it a strength that quantitative data is viewed as more scientific?
These results can be measured objectively.
Why is it a weakness that quantitative data lacks detail?
results are often superficial and lack validity
Why is it a weakness that quantitative data is narrow and unrealistic that only discusses small sections of behaviour?
This means the results may be less valid as there is no context
What is qualitative data?
data that can be expressed in detailed descriptions/words/images.
what questions does qualitative data use?
open questions, they answer in their own words with no formal measure
where do we get qualitative data from?
case studies, real world settings such as blogs and magazines, Field studies.
How do we analyse qualitative data?
thematic analysis.
Why is it a strength that qualitative data is rich in detail/emotion?
these results are more thorough and valid.
Why is it a strength that qualitative data can be analysed in more depth?
more specific themes can be drawn from the data. more holistic and valid.
Why is it a strength that qualitative data can be turned into quantitative?
the results can then be analysed statistically to see if results are due to chance or significant.
why is it a strength that qualitative data can be conducted in more natural circumstances?
Increases ecological validity and the results can be applied to a real life scenario?
What are the levels of measurement?
Nominal
Ordinal
Interval
Ratio
What is nominal data?
categorical data, e.g., brown eyes, green eyes, blue eyes.
what is ordinal data?
Ordered categories and distances between the categories isn’t set, e.g. a Likert scale, where numbers may be interpreted differently between participants.
What is Interval/Ratio data?
Scale data, test scores, weight temperature. set intervals
