What does accuracy refer to in measurement?
How close a measure relates to the ‘true’ value of the quantity being measured
Accuracy is crucial for ensuring the validity of research findings.
Define aim in the context of research.
A statement outlining the purpose of the investigation
The aim guides the direction of the research.
What is a bar chart?
A graph which uses a series of separate bars or rectangles next to, but not touching one another, to enable comparisons of different categories of data
Bar charts are commonly used for categorical data.
Define behaviour.
Any action made by a living person (or animal) that can be observed or measured
Behaviour is a key focus in psychological research.
What does beneficence mean in research ethics?
The commitment to maximising benefits and minimising the risks and harms involved in taking a particular position or course of action
Beneficence is a fundamental ethical principle in research.
What is meant by between subjects in experimental design?
An experimental design in which each participant is assigned to only one group or condition and provides only one score for data analysis
Also called independent groups and between groups.
Define biased sample.
A research sample that does not adequately represent the key characteristics of its population
Biased samples can lead to invalid conclusions.
What is a case study?
An intensive, in-depth investigation of some behaviour, event or problem of interest in a single individual, group, organisation or situation
Case studies provide detailed qualitative insights.
What does conclusion refer to in research?
A decision about what the results obtained from a research study mean
Conclusions are drawn based on the analysis of data.
Define confidentiality in research.
Ethical guideline for research involving the privacy, protection and security of a participant’s personal information, including results
Maintaining confidentiality is essential for ethical research practices.
What is a confounding variable?
A variable other than the independent variable that has affected the results (the dependent variable) and whose effect(s) cannot be separated from that of the independent variable
Confounding variables can obscure the true relationship between variables.
What is the control condition in an experiment?
The standard against which the experimental condition can be compared; involves the control group who are not exposed to the independent variable
Control conditions help establish a baseline for comparison.
Define control group.
The group in an experiment not exposed to the independent variable
Control groups are essential for determining the effect of the independent variable.
What is a controlled experiment?
An experimental investigation of the relationship between an independent variable and a dependent variable, whilst controlling all other variables
Controlled experiments help establish cause-and-effect relationships.
What is a controlled variable?
A variable that is considered to have an effect on the dependent variable so it is held constant to remove its potential effect
Controlling variables is crucial for the validity of an experiment.
Define correlation.
The degree of a relationship between two variables
Correlation does not imply causation.
What is a correlational study?
A research method used to investigate the relationship between variables without any control over the setting in which the relationship occurs or any manipulation by the researcher
Correlational studies can identify relationships but not causation.
What is a correlation coefficient?
A statistic used to describe the relationship between two variables
The correlation coefficient ranges from -1 to +1.
What does counterbalancing refer to?
Systematically changing the order of treatments or tasks for participants in a ‘balanced’ way to ‘counter’ the unwanted effects on performance of any one order
Counterbalancing helps control for order effects.
Define data in research.
Information collected through research; see also primary data, secondary data, quantitative data and qualitative data
Data is essential for analysis and drawing conclusions.
What is debriefing in research ethics?
Ethical guideline requiring that at the end of the experiment, the participant leaves understanding the experimental aim, results and conclusions including wellbeing checks where appropriate
Debriefing ensures participants are informed and supported.
What does deception mean in research?
When a researcher deliberately conceals the true purpose of the experiment from participants by misleading or misinforming them
Deception must be justified and debriefed afterward.
What is a demand characteristic?
A cue in an experiment that may influence or bias a participant’s response, thereby distorting the results
Demand characteristics can threaten the validity of the findings.
What is the dependent variable (DV)?
The variable the researcher measures, after selecting the independent variable that is assumed to have an effect on the independent variable
The DV is the outcome that is affected by the IV.
