Experimental Flashcards
Outliers
A value that lies a long way from other results.
Respect
All living things have value and are empowered to make their own decisions.
Controlled variable
Variables a researcher holds constant.
Personal errors
Mistakes and miscalculations by the researcher.
Between Subject design
Participants are randomly allocated to either the Experimental or Control group.
Uncertainty
A lack of exact knowledge of the value being measured; can identify possible causes of errors.
Confounding Variable
The variable that HAS affected the DV apart from the IV.
Extraneous Variable
A variable that isn’t the IV but MAY affect the DV if not monitored.
Within-Subject design
All participants are involved in both the Experimental and Control groups.
Systematic Errors
Cause the accuracy of a measurement to differ from the true value.
Random Errors
Unpredictable, affects the precision of a measurement.
Beneficence
The research maximises benefits and minimises risks and harm.
Investigation Methodology
The type of research study - how the data is gathered.
Mixed Design
Has elements of both Within and Between subjects design.
Precision
How closely a set of values agree with each other.
Repeatability
How close successive measurements are to each other (SAME CONDITIONS).
Non-Maleficence
The harm from the research doesn’t outweigh the benefits.
Classification and Identification
Arranging phenomena, objects or events into manageable or unique sets.
Accuracy
How close a measurement is to the True Value.
Controlled Experiment
Investigation of the relationship between 1 IV and a DV.
External Validity
The results can be applied to similar individuals in a similar setting.
Literature Review
Collating and analysing secondary data.
Modelling
Constructing or manipulating a representative model.
Integrity
Honest reporting, searching for knowledge.
Justice
No outcome of the research is unfair to one group over another.
Simulation
Using a model to study a real or theoretical system.
Fieldwork
Observations out of a lab/classroom.
Case Study
Individual or small group. Real-life situation.
True Value
The value found if the quantity could be measured perfectly.
Correlational Study
Studies the relationships between uncontrolled variables.
Validity
If the study measures what it is supposed to be measuring.
Reproducibility
How close successive measurements are to each other (CHANGED CONDITIONS).
Internal Validity
If the investigation investigates what it claims to investigate.
