data types Flashcards
qualitative
expressed i words non-numerical it expresses feelings or opinions and is used in diary’s or newspapers, harder to analyse
quantitative
numerical data, it can be easily analysed , found in form of multiple choice
primary data
field research , fist hand data , collected by researcher from their participants , specifically collected for the specific research being done
secondary research
desk research ,collected by someone other than the researcher, the data already exists before the research takes place.
where to find primary data
interviews or observations
where to find secondary data
journals, records, websites
meta analysis
it is a type of secondary research where lots of exiting studies from the same area of study are reviewed this could be so that researchers can discuss the findings of several studies and calculate effect size
effect size
Overall statistical measure of relationship across variables in a meta-analysis. This is the DV in a meta-analysis.
quantitative pros and cons
easy to analyse
easy to show statistical analysis
less open to bias
less objective
narrower scope
less detail
may not represent real life
qualitative
rich in detail
answers can be developed and so have more information
greater to real life
difficult to analyse
hard to put into category’s
comparisons can not be made easily so makes it hard to see dv
primary data pros ands cons
first hand data so more reliable
it is authentic and targeted
takes time and effort
is expensive
secondary data pros and cons
easy and quick as the data already exists
inexpensive
not specific to research
could be out of date therefore non reliable
content may not match researchers needs
meta analysis pros and cons
simple to to analyse statistically so comparisons can be easily made
less open to bias less objective
publication bias , only using date that has been published and may miss out ion other valid data for their study.
quantitative types of data
nominal - weak least precise
ordinal - strong more precise
interval - strongest most precise
how can qualitative data be converted to be used for mathematical calculations
