One of the primary differences between them is that research methods are the methods by which the research is conducted into a specific subject or a topic. On the other hand, research methodology explains the methods by which you may proceed with your research. What are Research Methods? Research methods can be defined as the various ways and means of conducting a research that involve the conduct of experiments, tests, surveys and the like.
Based on the cyclomatic complexity measure of McCabe, structured testing uses the control flow structure of software to establish path coverage criteria. The resultant test sets provide more thorough testing than statement and branch coverage.
Extensions of the fundamental structured testing techniques for integration testing and object-oriented systems are also presented.
Several related software complexity metrics are described. Summaries of technical papers, case studies, and empirical results are presented in the appendices.

Executive Summary This document describes the structured testing methodology for software testing and related software quality management techniques. The key requirement of structured testing is that all decision outcomes must be exercised independently during testing.
The number of tests required for a software module is equal to the cyclomatic complexity of that module. The original structured testing document [NBS99] discusses cyclomatic complexity and the basic testing technique.
This document gives an expanded and updated presentation of those topics, describes several new complexity measures and testing strategies, and presents the experience gained through the practical application of these techniques.
The software complexity measures described in this document are: The testing techniques are described for module testing, integration testing, and object-oriented testing. A significant amount of practical advice is given concerning the application of these techniques.
The use of complexity measurement to manage software reliability and maintainability is discussed, along with strategies to control complexity during maintenance. Methods to apply the testing techniques are also covered.
Both manual techniques and the use of automated support are described. Many detailed examples of the techniques are given, as well as summaries of technical papers and case studies.
Experimental results are given showing that structured testing is superior to statement and branch coverage testing for detecting errors. The bibliography lists over fifty references to related information.

5 is not only important for the researcher to know the research techniques/ methods, but also the scientific approach called methodology.
Research Approaches. A research method is a systematic plan for doing research. In this lesson, we'll look at the definition for a research method and examine the four most common research methods used.
Module 2: Study Design and Sampling Study Design.
Cross-sectional studies are simple in design and are aimed at finding out the prevalence of a phenomenon, problem, attitude or issue by taking a snap-shot or cross-section of the rutadeltambor.com obtains an overall picture as it stands at the time of the study. Social research is a research conducted by social scientists following a systematic plan.
Social research methodologies can be classified as quantitative and qualitative.. Quantitative designs approach social phenomena through quantifiable evidence, and often rely on statistical analysis of many cases (or across intentionally designed treatments in an experiment) to create valid and reliable.
