What particular aspects of the SPSS output would you look at to make your decision about the best model?
Step by step
Solved in 2 steps
- Outline the components of the classical experimental design. How is it different from a one-group pre-test post-test design?7 How many degrees of freedom (df) are associated with two different samples, 15 participants in each sample for a study investigating the effects of illumination of productivity under two treatment conditions?4. Why do you think most journals will not publish papers with an alpha = 0.1 ? Explain your answer using Type I or Type Il errors.
- A sample has a minimum value of 7 and a maximum value of 58 .Estimate its variance.J 1 Explain how length and lead time bias impacts the results of an evaluation of a screening program.22.) Using the parameter estimates in the JMP output, is there a problem with multicollinearity? YES NO CANNOT ASSESS Justification: What other method(s) may be used to assess multicollinearity?
- A cohort study is conducted to assess the association between clinical characteristics and the risk of stroke. The study involves n=1,250 participants who are free of stroke at the study start. Each participant is assessed at study start (baseline) and every year thereafter for five years. The following table displays data on hypertensive status measured at baseline and incident stroke over 5 years. Free of Stroke at 5 Years Stroke Baseline: Not Hypertensive 952 46 Baseline: Hypertensive 234 18 Compute the population attributable risk of stroke for patients with hypertension.The effects of developer strength (factor A) and development time (factor B) on the density of photographic plate film were being studied. Two strengths and two development times were used, and four replicates in each of the four cells were evaluated. The results (with larger being best) are shown in the following table: At the 0.05 level of significance, a. is there an interaction between developer strength and development time? b. is there an effect due to developer strength? c. is there an effect due to development time?Suppose that, as part of a research methods class, Bailey was asked to write a summary of a research paper on the topic of the effects of oil contamination in soil on seed germination rates. Identify the explanatory and the response variables.
- The dataset below was collected from a survey to determine whether CFT development in the island can be used as a strategy for the sustainable management and utilization of the fishery and aquatic resources in small islands. It shows the monthly income (in thousand pesos) estimated by 200 randomly selected fishers in Guimaras according to the type of fishers (i.e., the income source of fishers is solely fishing or they have alternative/supplemental livelihood such as island hopping services, sari-sari store ownership, fish value adding and/or vending, souvenir selling, carpentry, as construction worker, farming and tour guiding) and their perceived benefit from CFT development in the island. From this dataset and using = 0.05, is there a significant difference in estimated monthly income due tofisher type? How about due to the CFT perceived benefit? How about due to the interaction between fishertype and the perceived CFT benefit?a. Analyze manually and assume that the…What steps do I take on SPSS to do data screening for a T-Test?Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Boletus pinicola and published the results in the paper “Influence of Some Factors in Toxicity and Accumulation of Cd from Edible Wild Macrofungi in NW Spain” (Journal of Environmental Science and Health, Vol. B33(4), pp. 439–455). A hypothesis test is to be performed to decide whether the mean cadmium level in Boletus pinicola mushrooms is greater than the government’s recommended limit. Hypothesis tests are proposed. For each hypothesis test,a. determine the null hypothesis.b. determine the alternative hypothesis.c. classify the hypothesis test as two tailed, left tailed, or right tailed.
