the assumptions for using a chi-square test. Research articles provide practical examples from the research to support your assumptions. Include a citation of one article you used for your research
analysis of variance
which analysis of variance should be applied when an experiment has more than one independent variable. Discuss the assumptions and limitations of the analysis of variance in comparison with the t test including a discussion of post hoc tests
how a t Test for a dependent variable can be of great value in applying a new approach to the treatment of aggressive behavior to a small group of students. Why would this t Test be preferred to using another test statistic?
how a t Test can be employed in hypothesis testing by the use of directional vs. nondirectional hypotheses. Discuss types of research where using the t statistic may be an appropriate alternative to using a z-score. Respond to at least two of your fellow students postin...
True or False If f'(c)=0=f''(c)is less than 0, the f(c) is a local maximum. Justify your answer.
For each of the following samples that were given an experimental treatment, test whether these samples represent populations that are different from the general population: (a) a sample of 10 with a mean of 44, (b) a sample of 1 with a mean of 48. The general population of in...
For a population that has a standard deviation of 10, figure the standard deviation of the distribution of means for samples of size- (b) 3
Why is the ionic compound NaCl (table salt) able to dissolve in a glass of the molecular compound water (H2O)?
If 35.8 grams of LiCl are dissolved in 184 grams of water, what is the concentration of the solution in percent by mass?
What would be the resulting molarity of a solution made by dissolving 21.9 grams of KCl in enough water to make an 869-milliliter solution?
