AICE Psych Research Methods Vocab

Independent Measures

An experimental design in which different groups of pt. are used for esch condition.

Sample

Groups that participate in a study is called.

Population

Group of people in the community that you want to pull your sample from.

null hypothesis

A testable statement that states any correlation is due to chance.

True

Is a Situational Variable an extraneous variable?

Volunteer sampling

When pt's are invited to participate in a study through email or advertisement.

Opportunity Sampling

When pt's are chosen because they are available (ex. present where study is taking place)

Quantitative data

Data collected based on numerical results.

Demand characteristics

When pt. change their behavior to match the aim of the study, it is called

Order effects, practice effect, or fatigue effect

A weakness of repeated measures is:

Reliability or validity

When a procedure is consistent and produce same results when replicated, it has?

Field experiment

An investigation conducted in a normal environment and has a IV present.

Ecological Validity

When your study can be applied to a wide population.

Field

Barry is doing a study at a school to see how children are affected by teachers helping. What's the exp method?

Standardized

When you apply the same procedure to all pts. in each condition, then the study is__.

Natural Experiment

A study completed in a normal environment and the IV is not present.

Overt Observer

When the role of the observer is obvious to PT.

Covert Observer

When the observer is not obvious because they are hidden or disguised.

Experimental design

Matched Pairs is a type of

Any relevant participant variable

In matched pairs, participants are matched on

Independent variable

Variable that is being manipulated or controlled by the researcher.

Dependent Variable

Variable that is expected to change due to the independent variable

Repeated Measures

When the participants do both of the IV's

No participant variables or less people needed

Strength of treated measures.

Order effects or demand characteristics

Name a weakness of repeated measures design.

Lab Experiment

A research method that has IV, DV, and strict control.

Experimental Design

The way we allocate the participants into the IV is called

Qualitative Data

Data that is descriptive with in depth results

Aim

__ is to investigate a link or relationship between two measures variables.

Extraneous variable

Piliavin

All case studies under psychology lack mundane realism except.

Reflects the real world

Mundane realism is when a study

An interview with set pre-determined questions

What is a structured interview

Two tailed hypothesis

Does not state what direction the research results are expected to go.

One-Tailed Hypothesis

Predicts which direction the research results are expected to go.

Random sampling

a type of probability sampling in which the researcher randomly selects a subset of participants from a population.

hypothesis

educated guess based on what you've observed and can be tested
