CLARIFYING THE RESEARCH QUESTION THROUGH SECONDARY DATA AND EXPLORATION …
CLARIFYING THE RESEARCH QUESTION THROUGH SECONDARY DATA
A SEARCH STRATEGY FOR EXPLORATION
When researchers lack a clear idea of the problems they will meet during the study
individual depth interviews
Discovery and analysis of secondary sources
LEVELS OF INFORMATION
Secondary sources: interpretations of primary data, ex: encyclopedias, textbooks, handbooks, magazine and newspaper articles, and most newscasts
Tertiary sources: interpretations of a secondary source but generally are represented by indexes, bibliographies, and other finding aids
Primary sources: original works of research or raw data
TYPES OF INFORMATION SOURCES
INDEXES AND BIBLIOGRAPHIES
EVALUATING INFORMATION SOURCES
MINING INTERNAL SOURCES
DATA MINING: discovering knowledge from databases stored in data marts or data warehouses to identify valid, novel, useful, and ultimately understandable patterns in data
DATA WAREHOUSE: an electronic repository for
databases that organizes large volumes of data
=> DINAMICALLY ACCESSIBLE
DATA MART: compile locally required information. The entire system must be constructed for integration and compatibility among the different data mart.
EVOLUTION OF DATA MINING
Data collection => Data access =>data navigation => data mining
DATA MINING TECHNOLOGY
PREDICTING TRENDS AND BEHAVIORS: examples of predictive problems: targeted marketing, forecasting bankruptcy and loan default
Modify: Modify or transform data.
Model: Develop a model that explains the data relationships.
Explore: Identify relationships within the data.
Assess: Test the model’s accuracy.
Sample: Decide between census and sample data.
THE QUESTION HIERARCHY:
HOW AMBIGUOUS QUESTIONS
BECOME ACTIONABLE RESAERCH
THE MANAGEMENT QUESTION
the restatement of the management dilemma in question form.
An unstructured exploration allows the researcher to develop and revise the management question and determine what is needed to secure answers to the proposed question.
THE RESEARCH QUESTION
best states the objective of the business research study
more specific answers => more necessary
information to make decision
FINE-TUNING RESEARCH QUESTION
represent the information that the decision maker needs to know
must answer to satisfactorily arrive at a conclusion
actual questions that researchers use to collect data in a study.
Custom-designed measurement questions
Predesigned measurement questions
