![]() ![]() Alternative Hypothesis (H a): Factor 1 is not independent of factor 2.Null Hypothesis (H 0): Factor 1 is independent of factor 2.In other words, it can be used to test whether there is any statistically significant relationship between two discrete factors. The chi-square test can also be used to test whether two factors are independent of each other. The symbol k is the number of populations of our interest k ≥ 2. Alternative Hypothesis (H a): At least on of the proportions is different from others.Null Hypothesis (H 0): p 1 = p 2 =… = p k.There are multiple chi-square tests available and in this module we will cover the Pearson’s chi square test used in contingency analysis. a specified value, and the proportions of two populations, but what do we do if we want to analyze more than two populations? A chi-square test is a hypothesis test in which the sampling distribution of the test statistic follows a chi-square distribution when the null hypothesis is true. You may assume that the checks on identity and location are adequate.We have looked at hypothesis tests to analyze the proportion of one population vs. If you conclude that there is a relationship, describe it. Include discussion of assumptions and take appropriate action regarding any problems. 0mg 10mg 20mg 40mg 80mgBack Pain 15 55 9 11 15 No Back Pain 251 816 66 72 88Test the hypothesis that, among Australians aged 30 – 50 years, occurrence of back pain is un- related to statin dose. The table below summarises participants’ journal entries regarding back pain, classified by statin dose. Confirmation of statin dosage (if any) was obtained from their doctor. After screening, accepted participants were asked to maintain a daily diary for a week via an online form that asked about a range of possible side-effects. No applications were accepted from addresses that lay outside Australia or appeared to be aliases. Volunteers were screened to ensure that none had the same address, or belonged to the same family, and no more than 5 shared the same postcode. ![]() A small fee was offered to accepted participants, and evidence of identity was required (e.g., driver’s licence). One study advertised for volunteers aged 30 – 50 years who were ei- ther currently taking statins under medical supervision, or not taking statins at all. However, they are known to have some unfortunate side-effects. Statins are widely prescribed to treat high cholestorol.
