areas of research Flashcards
quantitative data
-data gathered such that they can be quantified (numbers)
-examine relationships among variables
-determine if discoveries are generalizable
-statistical analysis
-can be easier to summarize or bring together
-more objective, use same thing to measure people (can compare between tests easier)
-giving up personal perspective
usually self report **
qualitative
data gathered such that they can be analyzed through informed judgment (words)
-smaller focused samples
-focus is on the complexity of the phenomenon
-how we asked qustions will effect answers
quantitative data generally gathered by….. and used for…
surveys/questionnaires/physiological or performance measures
hypothesis testing
qualitative data generally gathered by… generally used for…
researcher is the “instrument” for collecting data through interviews, open-ended responses on surveys
exploring concepts - hypothesis-generating
big difference bw what quantitative and qualitative data have
Qualitative research has no variables**
as soon as u apply frequencies or counts then we have quantitative data**
mixed methods
both quantitative and qualitative methods are included within a research study
-more than simply collecting and analyzing both kinds of data
-strength of study is greater than either approach alone
strengths of qualitative study usually..
weakness of quantitative study and vice versa
quantitative surverys measure
thoughts
perceptions
attitudes
personality
emotions
behaviours
quantitative surveys guided by
theory
-theories guide conceptual framwork for measurement
-trait or state ?
-one dimensional or multidimenesional
multidimensional subscales influence one score at the end
quantitative surveys factors / issues
validity (accuracy) and reliability
-social desirability : responses that make the responder look better
-acquiescence : tendency for survey respondents to agree with statements regardless of their content particularly when they are unsure of the answer
(acquee = agree)
quant surveys factors cont
extremity : tendency to endorse the most extreme response categories regardless of the question
leniency : unrealistically favourable rating to a known person
(leanient with kid, rate higher)
performance measures
speed, accuracy
reaction time
force
balance/stability
motion analysis
movement skills
physical/physiological measures
weight, height, BMI , body fat, lean mass
BP, CV disease indicators, hormones, cardiac output, lung volume, resting met rate
MRI fMRI CAT scans
micronutrients (vits/mins)
data collection in qualitative data
interviews
observations
visual method
media
interviews
uncover whats not directly observable
discover what meaning experience has for individual
participants perform (make themselves sound good, looking for certain answer)
want to remain neutral
make participants comfortable
