Data structure is the structural representation of logical relationships between elements of data. Data structure mainly specifies the structured organization of data‚ by providing accessing methods with correct degree of associativity. Data structure affects the design of both the structural and functional aspects of a program. Algorithm + Data Structure = Program Data structures are the building blocks of a program. The programmers have to strive hard to solve these problems. If

source code modules written during the previous week‚ or all the modules in a particular subsystem‚ or all modules written in a particular language may cause biases to enter the sample that would not allow statistically valid generalization. Advantages ü There is no need to have a sampling frame for the whole population. ü usually less costly comparing to random sampling such as stratified ü researcher can increase sample size with this technique Disadvantages ü Selection may be biased since

johnk@ce-asia.com Annie Wong Director Corporate Edge Asia anniew@ce-asia.com ABSTRACT This research evaluates the effectiveness of using a management simulation‚ a management game or case studies within a strategic management training programme. The literature suggests that there is anecdotal evidence that both simulations and games surpass the use of case studies‚ but there is much criticism of the lack of robust research models used to validate the claims. Using a quasi-experimental design with a reliable

Educator’s Guide to Classroom Research by Nancy Fichtman Dana and Diane Yendol-Hoppey. Joining a book club is not new for me. Every year‚ I participate in book circles with my school division to engage‚ discuss and debate relevant ideas in education with colleagues. By joining this book club‚ I was hoping to review and analyze the content from my Introduction to Research Methods course with the professional development model in my division to develop a deeper understanding of research and professional inquiry

Examine the use of one research method used in the biological level of analysis‚ including an evaluation of the ethical considerations related to them. The case studies method consists in taking a patient personal history in order to take a diagnosis. It is usually applied in persons that have abnormal characteristics in behaviour‚ at biological or at cognitive level; it can also be applied to a group of people that are under the same situation. Case study is a long-term research where the patient

Scientific Method The Scientific Method is a system devised to allow scientists to gain insight‚ or knowledge‚ on a wide range of questions about one’s behavior and other points of interest. The first step in this process is to identify a question that deserves an explanation or answer to. For example‚ a good indentifying question that one could use would be why did the chicken cross the road? This is a specific behavior that can be addressed and quantified. Once the individual has the question

The Scientific Method What is the Scientific Method? “The Scientific Method is a logical and rational order of steps by which scientists comes to conclusions about the world around them that helps to organize thoughts and procedures.”1 The process of the Scientific Method is used by making an observation‚ forming a hypothesis‚ testing the hypothesis‚ analyzing data and then coming up with a conclusion. Scientists use the scientific method to search for cause and effect relationships in nature.

Inquiry Method Steps 1. Ask a question or identify the problem – What do you want to learn about? This question forms the starting point for inquiry. Example: You may be interested in discovering what methods of studying lead to better exam results. 2. Develop a hypothesis – A hypothesis is possible answer to your research question. Your hypothesis gives you direction. It helps you to determine what needs to be tested and which research method you will use. Example: You may hypothesize that
