Exploratory Research

Initial research conducted to clarifyand define the nature of a problem

Does not provide conclusive evidence

Subsequent research expected


7/19

Descriptive Research

Describes characteristics of apopulation or phenomenon

Some understanding of the nature ofthe problem


8/19

Causal Research

Conducted to identify cause andeffect relationships


9/19

Identifying Causality

Evidence of causality:

1. The appropriate causal order ofevents

2. Concomitant variation--two

phenomena vary together 3. An absence of alternative plausible

explanations
