EXERCISE 36 6. Can ANOVA be used to test proposed relationships or predicted correlations between variables in a single group? Provide rationale for your answer. ANOVA cannot be used to test proposed relationships or predicted correlations between variables in a single group because it is designed to test for correlations and interactions amongst groups‚ i.e. in the test group of patients with OA you are testing the correlations between those who do not use GI and PMR and those that do. Although

The antifeedant activity of the extracts choice and no-choice test methods‚ after 24 and 48 hours in each test‚ against 7 day old (3rd instar) larvae of S. litura on castor leaves. Stock solutions of the test compounds were prepared in the carrier solvents. Further dilution was done in emulsified water by maintaining emulsifier (Tween – 80) level at 0.5 % to yield various concentrations. Castor leaf discs (4 cm diameter) were punched out from the washed and dried castor leaves. Leaf discs were dipped

Source credibility Source credibility‚ is about the source and spokesperson’s credibility. From previous literature‚ source expertise and trustworthiness are crucial to be transmitted from a credible source. The spokesperson’s credibility has the following characteristics: to possess relevant expertise on the information topic‚ and to be trusted to transmit objective opinions (Hussein‚ 2012). Other studies state that the source’s expertise is the level of convincing. Convincing means that the communication

Exercise 36 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. The F-value is high enough at the 5% level of significance to suggest a significant difference between the control and treatment groups. The p-value 0.005 < 0.05 hence this suggests a rejection of the null hypothesis
