Web-based or online surveys
The proportion of variance accounted for by the treatment, or the difference between a treatment and control group measured in standard deviation units.
Effect size
Use this design to study cause-effect relationships.

This type of data requires the use of advanced technology and can increase the expense of data collection.
Biobehavioral Data
You can control random error by ____
The use of uniform procedures
There are this many types of data collection instruments.
Seven
These four factors govern statistical power.
The statistical test, the alpha level, the sample size, and the effect size.
This research design is a fallback strategy for situations in which random assignment is not feasible.
Quasi-Experimental Design
This type of data is based on events, actions, or circumstances.
Observational Data
ACASI stands for which data collection instrument
Audio computer-assisted self-interview
This type of data that may include meeting minutes, journals, and program reports.
Documents
This data collection may be a manual coding sheet for recording information from a paper file folder or the data collector may use a portable computer to enter information directly into a preformatted research database.
