B1: GENERAL ISSUES Flashcards
AIMS
A broad statement of the purpose of the research.
- intends to find out, often based on previous research or studies
- focused, researchable, practical & use specific language
VARIABLES
The events, characteristics, behaviours, or conditions the researcher measures & studies.
- IV
- DV
- Co-variables
- CV
- EV
INDEPENDENT VARIABLE
The variable that is being manipulated or changed by the researcher, often the difference between conditions.
DEPENDENT VARIABLE
The variable that is measured by the researcher to establish the affect the IV has had.
The results obtained from measuring dependent variable will show the research to establish cause & effect.
CO-VARIABLES
The variables within a correlation & refer to the two variables within a correlation being correlated to establish whether there is a relationship between them.
OPERATIONALISATION
Variables that are explained in ways that are detailed, objective + measurable.
For example, to record people’s mood, a survey could be used w/ a scale of 1-10 how they feel every hour.
CONFOUNDING VARIABLES
Variables in a study that are not being measured or manipulated by the researcher but affect the results of SOME (or Certain) participants’ behaviour.
- Inconsistent & quite difficult to control
- Negative consequences for validity
EXTRANEOUS VARIABLES
Variables in a study that are not being measured or manipulated by the researcher but affect the results of ALL (or Every) participants’ behaviour equally.
- Generally consistent
- Negative consequences for validity
Hypotheses
A predictive statement about what the researcher expects to find.
Experimental/Alternative hypotheses
Experimental = when an experimental research method has been used
Alternative = when a non-experimental research method has been used
Directional hypotheses
It predicts the IV WILL affect the DV and states EXACTLY how this difference will occur.
- Researcher is confident about what they expect to find.
Non-directional hypotheses
It predicts the IV WILL affect the DV BUT does NOT state exactly how.
- Researcher is unsure about what they may find.
Null hypotheses
It predicts that the IV will have NO affect on the DV.
- There will be no significant difference between the two conditions.
Target population
The group of individuals the researcher is interested in.
- e.g. young people in the UK
Sampling frame
A smaller group of people within the TP.
