In hypothesis testing, the ANOVA, T-Test, or Chi-Square is used to investigate if a hypothesis’s mean is true or false. Hypothesis testing involves developing the null hypothesis, choosing the suitable test static, identifying the statistical significance, deciding the decision rule to reject or not reject the null hypothesis, and collecting the data and completing the required calculations. The null hypothesis is simply a statement, which the investigator comes up with, that is being tested. Static testing involves using a value that is consistent and is computed from the data, such as the mean or mode. It measures the similarity or dissimilarity between the data and the null hypothesis.
The second method was also used considering that two points along the best fit line were exactly one cycle away, meaning the value of H2 was ten times larger than the value of H1. Equation 3 was used in this method. It became easier since the value of log10 is equivalent to 1. After Q1 and Q2 were chosen at the H values, the next step is to solve for log Q2/Q1. This calculated value of n came out to be 0.5057.
The criteria for inclusion & exclusion should be appropriate in such a way that there are minimal confounding factors which will interfere in the results. The statistical techniques used for deriving the results will be checked for their appropriateness. The discussion will be reviewed to highlight whether it reflects the results obtained in the study. The conclusion will be checked if it actually achieved the objective of the study. References will be analysed to check its completeness, relevance and current or old

Taking an example of a laboratory it should consist of a particular organizational structure and protocols to carry out and document laboratory work. Traceability and integrity of data are also important along with the quality of the data. The type and amount of documentation forms the major difference between GLP and Non-GLP. GLP inspector looks after documentation and to easily find out the following: • Person who has done a study, • The overall procedure on how the experiment was carried out,- • Which procedures have been used in the experiment, and • Any problem faced and if so • How it has been solved. There are few requirements of a GLP system which are as follows: • Responsibilities should be assigned for the management of sponsor, study and quality assurance unit.
Test plans and their relationship with other test artifacts From a test plan you can manage other test artifacts, such as test cases and requirements. The topic on test artifact relationships describes the relationships between tests plans and other test artifacts, such as test cases, requirements, test scripts, keywords, test data, and so on. Test execution status From the test plan overview you can track the test execution status of test cases and test suites. User can view the relationship between test estimates and actual time spent, test execution progress in relation to the assigned weight (or point) values, and test execution status in relation to the number of tests attempted. Test plan tasks Here are some of the tasks that user can perform with test plans: • Set up a formal review process that is visible at all times to all members of the larger project
Researchers using grounded theory technique must develop the required theoretical sensitivity to find out “substantive, grounded categories” (Glaser, 1978). This is an essential requirement in the course of going beyond description to conceptual theory (Guthrie 2000). Grounded theory enables to analyse relationships and attitude within a phenomenon from an impartial comprehensive viewpoint. Thus, when a researcher starts a study with no structure or theory, they are desired to fit the data into the way which are open to determining justification that have to be expressed. More significantly, the explanations finally come from the participants being studied.
Since the conclusion of deductive reasoning is correct when premises used are also true, there must be certainty that premises used truly right. The deductive proofing process will involve a theory or a mathematical formula which has already been proven to be deductive as well. In inductive reasoning, general conclusions are built on factors collected through directional observation. It means, someone can gain knowledge by observing the natural surroundings and the fact that occur, then make a general conclusions. How to draw conclusions on this inductive reasoning has opposite way with the deductive reasoning.
For performance of a research, its methodology must be clear to the researchers. A clear methodology indicates the methods or techniques to be used as well as their relevance for the study. In choosing an appropriate methodology Guba& Lincoln (1994, pg. 105) argue, “Questions of method should be secondary to questions of paradigm”. The issue is one of choosing the most appropriate research method to achieve stated research objectives.
Introduction_______________________________________________________________ In this essay I will attempt to critically analyse the above statement by accessing the validity and reliability in a number of assessments. First of all we need to pass a critical eye over both validity and reliability. The statement above states that these are the foundations of underpinning assessments. But what exactly does validity and reliability mean? The definitions for these terms are, Reliability is the extent to which an "experiment, test, or any measuring procedure yields the same results on repeated trials.
