Testing of hypothesis in research methodology

Practice Test Procedure for hypothesis testing means to tell on the basis of the data the researcher has collected whether or not the hypothesis seems to be valid. In hypothesis testing the main question is: Procedure for hypothesis testing refers to all those steps that we undertake for making a choice between the two actions i.

The various steps involved in hypothesis testing are stated below: Making a formal statement: The step consists in making a formal statement of the null hypothesis H0 and also of the alternative hypothesis Ha.

This means that hypotheses should be clearly stated, considering the nature of the research problem. Mohan of the Civil Engineering Department wants to test the load bearing capacity of an old bridge which must be more than 10 tons, in that case he can state his hypotheses.

The average score in an aptitude test administered at the national level is The state wants to know if there is a significant difference between the local scores and the national scores. The formulation of hypotheses is an important step which must be accomplished with due care in accordance with the object and nature of the problem under consideration.

It also indicates whether we should use a one-tailed test or a two-tailed test. Selecting a significance level: The hypotheses are tested on a pre-determined level of significance and as such the same should be specified.

The factors that affect the level of significance are: In brief, the level of significance must be adequate in the context of the purpose and nature of enquiry. Deciding the distribution to use: After deciding the level of significance, the next step in hypothesis testing is to determine the appropriate sampling distribution.

The choice generally remains between normal distribution and the t-distribution. The rules for selecting the correct distribution are similar to those which we have stated earlier in the context of estimation.

Selecting a random sample and computing an appropriate value: Another step is to select a random sample s and compute an appropriate value from the sample data concerning the test statistic utilizing the relevant distribution. In other words, draw a sample to furnish empirical data.

Calculation of the probability: One has then to calculate the probability that the sample result would diverge as widely as it has from expectations, if the null hypothesis were in fact true. Yet another step consists in comparing the probability thus calculated with the specified value for athe significance level.

In case we reject H0, we run a risk of at most the level of significance committing an error of Type I, but if we accept H0, then we run some risk the size of which cannot be specified as long as the H0 happens to be vague rather than specific of committing an error of Type II.Introduction.

Methodology is perhaps the most challenging and laborious part of research work. Essentially, the methodology helps to understand the broad philosophical approach behind methods of research you chose to employ for your study. This means that your methodology chapter should clearly state whether you chose to .

Aug 28,  · Qualitative research is not really designed for hypothesis testing. It is designed to explore an area that can later be hypothesis tested with a quantitative approach (or alternately, it can be used to explore the meanings of quantitative answers in more detail).
