Research Methods in Psychology

What type of data is measured in numbers?

• Qualitative

• Categorical

• Descriptive

• Quantitative

Which design involves repeating the same test with the same participants?

• Matched pairs

• Repeated measures

• Independent measures

• Volunteer sampling

What is a confounding variable?

• A variable the researcher manipulates

• A variable that affects the DV but isn't controlled

• Another term for DV

• A random error

What increases reliability?

• Demand characteristics

• Standardized procedures

• Ecological validity

• Subjective scoring

A double-blind experiment prevents:

• Standardization

• Demand characteristics

• Experimenter bias

• Ecological effects

What's the purpose of a pilot study?

• Increase ecological validity

• Collect data

• Recruit more participants

• Test procedures beforehand

Which method is a type of experiment where the IV is naturally occurring?

• Lab

• Field

• Quasi

• Case Study

What is inter-rater reliability?

• Reliability across different tests

• Agreement between raters

• When DV stays constant

• Ecological consistency

What is population validity?

• If results apply to all settings

• How well variables were defined

• If results generalize to other people

• If a test measures what it says it measures what it says it does

Volunteer sampling can lead to:

• Less bias

• Low reliability

• Demand characteristics

• Biased sample
