What is the technique called for observing and measuring responses are the same for all participants?

What is an experimental research design for which each participant is randomly allocated to one of two entirely separate conditions?
Beneficence
When there are potential benefits of the research to participants or the wider community this is called?
Extraneous variable
What is the name for any variable other than the IV that can cause a change in the DV and therefore affect the results in an unwanted way?
Dependent variable
What is the name of the variable in an experiment the researcher chooses to measure to assess the effect(s)?

Conclusion
What is the name of the decision about what the results obtained from a research study mean called?
What is unwanted influence on the results produced by the person carrying out the research called?
Random allocation
What is the name of the procedure used to assign participants to experimental and control groups so everyone has an equal chance of being placed in any of the groups?
Order effect
What is it called when the DV is influenced by the specific sequence in which experimental tasks are performed, rather than the IV?

What is the experimental design that involves participant’s written or spoken responses to questions, statements or instructions presented by the researcher?
p-value
What is the name of the statistically significant value at which chance is likely to have operated on the results obtained from research?
Confounding variable
What is the name of the variable other than the IV that may have an unwanted effect on the DV?

What is the sampling procedure involving selecting participants who are readily available?
Counterbalancing
When an experimenter systematically changes the order of treatments or tasks in a way to prevent any unwanted effects on performance of any one order, this is called?
Repeated measures design
What is the design used when participants are part of the control group and experimental group?
Validity
The extent a tool accurately measures what it claims to have measured refers to its?
When the findings of a research study can be applied to the population from which the sample was drawn?
Stratified sampling
What is the sampling that involves the experimenter ensuring that particular groups are represented proportionally to how they occur in a population?
Double blind procedure
What is the design called when neither the participants or researcher knows which participants are in an experimental or control group?
Matched participant design
What is the design used when a researcher wants the advantage of having participants with similar scores on the variable they are controlling?

When a measurement tool produces results that are consistent, dependable and stable this confirms refers to its?
