types of data Flashcards
qualitative data
expressed in words and non-numerical
quantitative data
counted, usually given in numbers
primary data
information that has been obtained first hand by a researcher for the purpose of gathered directly from participants as part of experiment, self-report or observation
secondary data
information that has already been collected by someone else and so predates the current research project
meta analysis
the process of combining the findings from a number of studies on a particular topic
- the aim is to produce an overall statistical conclusion based on a range of studies
where is quantitative data used ?
recall memory experiment
how is primary data gathered ?
conducting an experiment, questionnaire, interview or observation
where is secondary data found ?
journal articles, books or websites
qualitative data - evaluation
- greater external validity than quantitative data - provides the researcher with a more meaningful
insight into the participants world view - difficult to analyse - lend itself to being summarised statistically so that patterns and comparisons withing and between data may be hard to identify
- rely on the subjective interpretations of the researcher ad these may be subject to bias
quantitative data - evaluation
- simply to analyse
- more objective and less open to bias
- much narrower in meaning and detail
- may fail to represent real life
primary data - strength
strength: fits the job
- authentic data obtained from the participants themselves for the purpose of a practical investigation
primary data - limitation
requires time and effort on the part of the researcher - considerable planning, preparation and resources
secondary data - strength
inexpensive and easily accessed requiring minimal effort - researcher may have found the desired info which already exists
secondary data - limitation
may be outdated or incomplete - may not match the researchers needs or objective - challenge the validity of any conclusions
meta analysis - strength
creates a large, more varied sample and results can than be generalised across much larger populations which increases validity
