Quantitative Research Review RDL 2

A one-shot survey for the purpose of describing the characteristics of a sample at one point in time.

• Descriptive Survey

• Longitudinal Survey

• Cross-Sectional Survey

ONE group is studied at DIFFERENT POINTS IN TIME.

• Descriptive Survey

• Longitudinal Survey

• Cross-Sectional Survey

How close a measurement is to the true value is called..

• Accuracy

• Precision

• Significant

• Estimate

This research method is a measure of the extent to which two variables change together, and thus of how well either variable predicts the other

• Correlational
• Experiments
• Case Study
• Survey
• Observational

A type of research method that investigates the effect of an IV on a DV.

• Correlational study

• Experimental method

• Case study

• Brain imaging

Any factor a researcher must consider in order to reduce possible negative effects of the research on participants or other people.

• Participant variability

• Extraneous variable

• Ethical consideration

• Generalizability

A study that tests the effects of some kind of treatment on a dependent variable, but one or more characteristics of a true experiment can't be met.

• True experiment

• Field experiment

• Quasi experiment

• Natural experiment

Experimental design where people take part in only one condition but they have been carefully matched with another person in the other group based on any participant variables that might affect the DV (e.g. IQ, personality)

• independent measures

• repeated measures

• matched pairs

The extent to which findings can be generalised to other peoples, times, settings

• External validity

• Ecological validity

• Internal validity

• Temporal validity

The extent to which the effects of the study are due to the manipulation of the IV

• Face validity

• Content validity

• External validity

• Internal validity
