CORRELATION RESEARCH DEFINITION: Correlational research tests for statistical relationships between variables. The researcher begins with the idea that there might be a relationship between two variables. She or he then measures both variables for each of a large number of cases and checks to see if they are in fact related. The relationship of interest could be either a D relationship or an R relationship‚ so this might involve making a bar graph and computing D or making a line graph

Their client has offered samples to be analyzed‚ so they can quickly learn whether the process is operating satisfactorily or corrective actions needs to be taken. The numbers given in the case were as follows: assumed population standard deviation is equal to .21‚ sample size is equal to 30 and the test value of the mean was 12.

Invariance considerations imply the MANOVA statistic should be a measure of magnitude of the singular value decomposition of this matrix product‚ but there is no unique choice owing to the multi-dimensional nature of the alternative hypothesis. The most common[3][4] statistics are summaries based on the roots (or eigenvalues) λp of the A matrix:

MB 0050 Research Methodology Ques 1 Research is a sequential method of enquiry‚ directed towards a clear implicit or explicit objective. Describe in detail the steps to be carried out in a typical research study. Ans. Different scholars have interpreted the term ‘research’ in many ways. For instance‚ Fred Kerlinger (1986) stated that ‘Scientific research is a systematic‚ controlled and critical investigation of propositions about various phenomena.’ Grinnell (1993) has simplified the debate and stated

Basing upon these discussions‚ this report will make some recommendations to Jenkins about his business plan. 2. Method of analysis The choice of statistical analysis is a very important work. The right choice of analytical method should not only help solve the issue to be analysed‚ but should also have strong robustness. The choice of statistical analytical method is dependent upon mainly three factors‚ namely the scale of data‚ the research design and the fundamental assumptions (Nargundkar‚

classifying research are as per the following: 1) Descriptive versus Analytical Research : Descriptive research deals with finding facts to establish the nature of something as it exists. In contrast analytical research deals with determining validity of hypothesis based on analysis of facts collected. 2) Applied versus Fundamental Research : Applied research is carried out to find solutions to practical problems to be solved and as help in decision making in different areas like engineering design and insurance
