TESTING A HYPOTHESIS
STEPS IN TESTING A HYPOTHESIS
Step 1 – Making Assumptions Two types of assumptions:
Assumptions that you know because you did it while conducting the research; and
Assumptions that you do not know - that is why you are conducting the test of statistics. This second assumption is your statement of the null and alternative hypothesis TYPES OF STATISTICAL HYPOTHESES
Null hypothesis. The null hypothesis, denoted by H0, is usually the hypothesis that sample observations result purely from chance.
Alternative hypothesis. The alternative hypothesis, denoted by H1 or Ha, is the hypothesis that sample observations are influenced by some non-random cause.
Step 2 - Identifying a Sampling or Probability distribution
Step 3 – Establishing a level of significance and critical region
Step 4 – Calculate/compute the test
Step 5 – Make decisions
Step 6 – Conclusions

    Research is a systematic process of critical enquiry leading to valid propositions & conclusions that are communicated to interested others1 and good research is reproducible. Research is a collective activity – each study drawing on what has gone before. The important aspect of which is, that it is a process that systematically involves a series of steps, and generally grows out of our human tendency to grow, learn and solve, finding things that work. The aim of research is to lead to the development and refinement of new knowledge that is based on concrete experiences or observations, as opposed to purely theoretical conjecture.2…

    7) HYPOTHESIS: What is your hypothesis? Remember a hypothesis contains three things: first it indicates the object of observation, the dependent and independent variables, and the direction of their relationship. For example: “the more I’m feeding my cat, the fatter she gets”. “Cat” is the object of observation, “food” is the cause, cat getting “fat” is the effect, and the direction of the relationship is positive.…

    The hypothesis testing procedure consists of five steps. In the first step, the researcher will restate the question and form the research hypothesis. The null hypothesis will be the complete opposite of the research hypothesis. The second step is to determine the characteristics of the comparison distribution. The comparison distribution is the distribution that represents the population situation if the null hypothesis is true. Step three will be to determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected. In…
