Purpose of Research
Exploratory

Types of Investigation

Broad

Correlational (associations)

Increase general understanding of
context

“Are smoking and cancer related?”

Causal (directional)

Descriptive

“Does smoking cause cancer?”

Identify variables
Identify relationships

Hypothesis testing
Analytical or Predictive

Usually requires manipulating the
precedent variable

Focused

Varying degrees of manipulation
Controlling the independent variable
Usually requires longitudinal study

Nature of relationships
Nature of (explanation) of variations of the
variables

Scenario #1

Time

A manager is intrigued why some people
seem to derive joy from work and get
energized by it, while others find it
troublesome and frustrating.

Cross Sectional
Point in time

Identify the purpose of the study

Longitudinal

Correlational

The type of investigation

Time Series

Hypothesis testing

Continual
Incremental
Cross-Sectional

The extent of researcher interference
Minimal

The study setting
Field study

The time horizon for the study
One-shot (cross-sectional)

The unit of analysis
9

Scenario #2

Would this be a causal or correlational study?
Causal

Is this exploratory, descriptive, or hypothesis
testing (analytical or predictive) study?
Hypothesis testing – analytical (causality)

The extent of researcher interference

Many were concerned about the operations of
the infamous BCCI, the international banking
institution. If the Government had desired to
probe into the details, would this investigation
have called for:
A causal or correlational study?
Correlational – probe into details, not causes

An exploratory, descriptive, or hypothesis
testing (analytical or predictive) study?
Descriptive – describing operations

Minimal

What kind of study would this be: Field study,
field experiment, or lab experiment?
Field experiment (manipulation required)
Individual (operators)

Exercise 6.2

A foreman things that the low efficiency of the
machine tool operators is directly linked to the
high level of fumes emitted in the workshop.
He would like to prove this to his supervisor
through a research study.

What will be the unit of analysis?

Individual

A field study, field experiment, or lab
experiment?
Field study – natural environment

Cross-sectional or longitudinal study?

12
Cross-sectional – collected at one point in time
