survey design
Descriptive design type involving data obtained through subjects' self-
report
-most common descriptive design
strengths and weaknesses: Survey Design
Strengths: Large samples, inexpensive, anonymous
Limitations: Superficial answers, socially desirable answers
Prospective Studies
Studies over time with presumed causes that follow subjects to determine
whether the hypothesized effects actually occur
Retrospective Studies
Research designs when researchers look back in time to determine
possible causative factors
