Research Design
This document discusses research design and its key elements. It defines research design as the basic outline or blueprint of a research study that helps collect and analyze data to find outcomes. A good research design is efficient, flexible, appropriately designed, and helps avoid misleading paths. It includes questions about the study purpose and significance. Research design has four parts: sampling design, observational design, statistical design, and operational design. Key elements are a clear problem statement, objectives, literature review, population and sample, data collection and analysis methods. The document also explains terms like dependent and independent variables, extraneous variables, control, and experimental designs. It discusses research design for exploratory and descriptive research.
Research design
Research design is a plan or blueprint that outlines how research will be conducted to answer the research question. It specifies the methods and procedures for collecting and analyzing needed information. A good research design is appropriate, efficient, economical, and flexible. It minimizes bias and experimental error while maximizing reliability and the information obtained. Research design can be exploratory, descriptive, or causal. Exploratory research aims to gain background information through methods like secondary data analysis or focus groups. Descriptive research describes situations through structured data collection and analysis. Causal research studies hypotheses about relationships between variables through experiments that reduce bias and rule out alternative explanations.

New PPT Research design
Research design provides a framework or blueprint for conducting research projects. It involves outlining how data will be collected and analyzed to answer research questions. There are two main types of research design: exploratory and conclusive. Exploratory research is aimed at gaining insight and understanding about a problem using flexible questions, while conclusive research uses formal, structured questions to provide statistical evidence to make decisions. Conclusive research includes causal research, which determines relationships between factors, and descriptive research, which describes market characteristics. Descriptive research can be cross-sectional, collecting a single snapshot of data, or longitudinal, collecting repeated data from the same sample over time.

Research design provides a framework for conducting marketing research projects by detailing the necessary procedures to obtain needed information. There are two main types of research design: exploratory and conclusive. Exploratory research formulates problems, identifies actions, develops hypotheses, and isolates key variables through methods like expert surveys, pilot surveys, and case studies. Conclusive research has clearly defined information needs, is formal/structured, uses large samples, and applies quantitative analysis and findings to decision making. Descriptive and causal research are also discussed.
Research process & design
Research is used in business decision making to apply scientific methods to management problems in a systematic way. The research process involves defining the problem, designing the study, collecting and analyzing data, interpreting results, and reporting findings. There are different types of research designs depending on whether the goal is exploratory, descriptive, or testing hypotheses. Exploratory research explores problems broadly while descriptive and experimental research more specifically describe characteristics or test relationships between variables.

Lesson 3
The document discusses different types of research categorized by purpose, process, and outcome. Research can be descriptive, analytical, exploratory, or predictive depending on its purpose.

RESEARCH DESIGN Research Design is the plan, structure and strategy of investigations conceived so as to obtain answer of research questions and to control variance. ----- Kerlinger The plan of attack: What approach to the problem will be taken? And what strategies will be most effective? A plan for selecting the sources and types of information used to answer research questions A framework for specifying the relationships among the study variables A blueprint that outlines each procedure from the hypothesis to the analysis
- 2. PROCESS OF DESIGNING AND CONDUCTING A RESEARCH PROJECT: What--What was studied? What about--What aspects of the subject were studied? What for--What is/was the significance of the study? What did prior lit./research say? What was done--How was the study conducted? What was found? So what? What now? 2 1. Introduction, Research Problems/ Objectives, & Justification 2. Literature Review 3. Methodology (Research sample, data collection, measurement, data analysis) 4. Results & Discussion 5. Implications 6. Conclusions and Recommendations for Future Research
- 3. ELEMENTS OF RESEARCH DESIGN The Problem The Methodology Data Gathering Data Analysis Report Writing Considerations while designing Research Design Useful and less costly Simplification of research Flexibility Minimize errors Reliability Appropriate Results
- 4. HISTORICAL RESEARCH DESIGN Analyzing the past events and develops the present concept and conclusion Analyzing the previous informations or events minutely and testing their validity The main purpose is to show the relevance of past events to present Depends upon data observed by other rather than investigator Depends upon primary sources and reviews of literature
- 5. DESCRIPTIVE RESEARCH DESIGN Fact finding from analyzing informations Assessing opinions, behaviors and to describe the situations and events. Process of accumulating facts Researcher collects, classifies and correlates data to describe what exists Related to prediction and explanation of facts

Longitudinal growth study: study people or events at different time periods. 2. Cross sectional growth study: Data are gathered just once: perhaps over a period of time.One shot study. 3. Trend study: Data are collected after a certain time interval 4. Cohort Study:Study of a group of people who have similar characteristics or experience.
