Minimization of false trends in measurement caused by extraneous variables can be minimized by:A. Randomizing the order of application of the independent variable.B. Repeated measurement of the dependent variables.C. Signal conditioning and recalibration of the test instrument.D. Neglecting controlled parametrization of fundamental features of the test instrument.E. Getting a new replacement of the test instrument.

You want to determine if diet impacts body weight. You recruit 60 subjects, assigning 20 each to either one of two dietary interventions or to maintain their normal diet. You measure body weight before and after the intervention and calculate the change in body weight (post minus pre weights). To determine the diet effect on the calculated change in body weight, you would use a .Assume all assumptions are met for a parametric test.

Katy is interested in Chinese language learning. She believes that the Chinese characters with different numbers of strokes may affect the reading performance. You are invited to help her to design an experiment. A)What is the independent variable (IV) in this study? If the IV is required to have THREE levels, how can you manipulate it? What is the scale of measurement of this IV? B) Please provide the operational definition for the dependent variable (DV)? How can you measure the DV you defined? What is the scale of measurement of this DV?
The relationship between the independent variable (IV) and the dependent variable (DV) is likely to be mediated by a third variable (MV). With regard to the statement above, which of the following is most likely to be correct? A IV = Students’ performance (i.e., marks) in the formative assessment; DV = Students’ performance (i.e., marks) in the summative assessment, and MV = Students’ level of comfort with the venue of the assessments B IV = Students’ performance (i.e., marks) in the summative assessment; DV = Students’ performance (i.e., marks) in the formative assessment, and MV = Students’ level of preparation for the assessments. C IV = Students’ performance (i.e., marks) in the formative assessment; DV = Students’ performance (i.e., marks) in the summative assessment, and MV = Students’ level of preparation for the assessments D IV = Students’ performance (i.e., marks) in the summative assessment; DV = Students’ performance (i.e., marks) in the formative assessment,…
Quality control at a soda bottler suspects that the variance in the mean volume of bottles of soda being filled by the bottler is intolerably high. In a sample of 14 bottles, the sample variance is 1.5 ml. Use this sample to test Ho: o? = 1.2 against H:0? > 1.2 at a = 0.05. a) Find the critical value or values for this test. b) Find the value of the test statistic. c) Give your decision in terms of the null hypothesis.
Compute test statistic (Independent t-score) Pooled variance S2p: Estimated standard error S(M1-M2) : Computed Independent t statistic: 2. Make a decision about the null hypothesis and state a conclusion. Decision: Are you going to reject the null or fail to reject the null Conclusion: ex. The independent variable did or did not have a significant effect Remember: if you reject, there was significance When people learn a new task, their performance usually improves when they are tested the next day, but only if they get 6 hours sleep (Sticckgold, et al., 2000). The following data demonstrate this phenomenon. The participants learned a visual discrimination task on one day. Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night. 6 hours sleep No sleep…
