name 3 types of scatter graph correlation
Zero
Negative
Positive
name at least 3 features of a normal distribution
Bell shape
symmetrical sides
asymptotic tail
mean, median and mode all at the peak
What is quantitative data?
data involving numbers
(remember: quantity = amount = numbers)
what is qualitative data?
data involving words or pictures
what is primary data?
Data collected for the purpose of the research being carried out. Collected first-hand from participants.
what is secondary data?
Second-hand data collected by someone other than the researcher- exists before the researcher’s investigation started.
eg- results of someone else’s study
Give some examples of quantitative data:
- closed question questionnaires
- observational studies with behavior categories
Give some examples of qualitative data
- unstructured, structured and semi-structured interviews
- open question questionnaires
- case studies
Define ‘overt observation’
the participants are
aware that they are being observed.
Overt= open, they are open with the
participants.
Define ‘covert observation’
The participant is
unaware that they are being observed.
Covert= covered up, they hide the fact they
are observing.
Define ‘participant observation’
The observer joins in (participates) with the group they are observing.
Define ‘non-participant observation’
The observer will watch from a distance and not join in with the activities.
Define ‘naturalistic observation’
The observation takes place in a natural setting.
Nothing is changed in the environment.
Define ‘controlled observation’
The environment where the observation takes place is set up and many aspects are controlled.
Define ‘Inter-observer reliability’
explain how you might control/remove bias from this
using 1 observer can mean
some things are overlooked or
not recorded (observer bias).
Using 2 observers avoids this as
they can check to ensure their
data is the same or similar.
