2- Correlational Research
3- Experimental Research
Research Methods
Descriptive Research
Name the 5 type styles
1-Observation
2-Surveys and Interviews
3-Standardized tests
4-Case studies
5-Life-history records
Research Methods
Descriptive Research
Define
Observation
Very Systematic
Observer must be unbiased, impartial and accurate
Observation can occur in natural or lab environment
STRENGTHS: can be done in a lab where variables are controlled
WEAKNESS: if done in a lab, subject may not be natural
Research Methods
Descriptive Research

Not a causation style
Goal is to describe the strength of 2 events or characteristic. Ex do pt's w/good attitude get D/C faster?
Research Methods

At least one EXPERIMENTAL GRP(whose experience is manipulated)
INDEP variable-CAUSE (the manipulated factor that causes change)
DEPENDENT variable-EFFECT (factor that is measured for change; it will change as indep var is manipulated)
RANDOM ASSIGNMENT
TIME SPAN of RESEARCH
4 time spans
1-Longitudinal
2-Cross-Sectional
3-Sequential
4-Cohort
TIME SPAN of RESEARCH
Define
Longitudinal
Long period, years.
Expensive
Subjects drop out, die, etc
BUT can provides a wealth of info
TIME SPAN of RESEARCH
Define
Cross-Sectional
Can use different aged groups and research is done fairly quickly, don't have to wait for subjects to age.
Not as costly, time effective
But info is weak in showing how individuals change
TIME SPAN of RESEARCH
Define
Sequential
Combination of longitudinal and cross-sectional:
expensive, time consuming, complex, BUT it provides info that cross-sectional or longitudinal can't provide alone
TIME SPAN of RESEARCH
Define
Cohort
Use subjects born around the same year, and have similar experiences, yet have different factors;like diff yrs of education, health, attidudes, child rearing practices, etc
