  1. PDF 1. Formulation of Research Hypothesis with student samples

    Your hypothesis is what you propose to "prove" by your research. As a result of your research, you will arrive at a conclusion, a theory, or understanding that will be useful or applicable beyond the research itself. 3. Avoid judgmental words in your hypothesis. Value judgments are subjective and are not appropriate for a hypothesis.

  2. PDF Introduction to Hypothesis Testing

    Hypothesis testing or significance testing is a method for testing a claim or hypothesis about a parameter in a population, using data measured in a sample. In this method, we test some hypothesis by determining the likelihood that a sample statistic could have been selected, if the hypothesis regarding the population parameter were true.

    The intent of hypothesis testing is formally examine two opposing conjectures (hypotheses), H0 and HA. These two hypotheses are mutually exclusive and exhaustive so that one is true to the exclusion of the other. We accumulate evidence - collect and analyze sample information - for the purpose of determining which of the two hypotheses is true ...

  8. PDF Two Samples Hypothesis Testing

    Statisticians refer to this case (equal n in the two samples) as a paired samples hypothesis test. The procedure is very similar to the single-sample hypothesis tests we have already discussed, except that we replace variable x by the difference between the two variables, δ = x − x . B A.

  9. PDF Hypothesis Testing

    Hypothesis testing is formulated in terms of two hypotheses: H0: the null hypothesis; H1: the alternate hypothesis. The hypothesis we want to test is if H1 is \likely" true. So, there are two possible outcomes: Reject H0 and accept H1 because of su the sample in favor or H1; cient evidence in.

    Effect size. Significance tests inform us about the likelihood of a meaningful difference between groups, but they don't always tell us the magnitude of that difference. Because any difference will become "significant" with an arbitrarily large sample, it's important to quantify the effect size that you observe.

    Step 1: The hypothesis statement is H0: μ = 150 versus H1: μ ≠ 150. Observe that μ represents the true-but-unknown mean for the new Krisp-o-Matic machine. The comparison value 150 is the numerical claim, and we want to compare μ to 150. It might seem that the whole problem was set up with H1: μ < 150 in mind.
