Describe a scenario where a researcher could use a Goodness of Fit Test to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to use? (3 points) Describe a scenario where a researcher could use a Test for Independence to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to...
Briefly describe a scenario (real world or hypothetical) where Democratic leadership style would (or has) not be (been) effective (would be considered a con).
-It would not be appropriate to use the Mann–Whitney U test when: a researcher is comparing two independent populations. the dependent variable is measured at the ordinal level. the assumptions for an independent-samples t test are not met. a researcher is comparing three or more groups on a normally distributed dependent variable. -Kia assesses people's levels of gratitude and stress that occur naturally to determine if a relationship exists between the two variables. Kia is using a(n): correlational design experimental...
1. Describe a study where a one-way ANOVA would be appropriate (hint: how many independent variables are there in a one-way ANOVA?). Make sure to tell us your independent and dependent variables. 2. What would you hypothesize in terms of the effect of your IV on your DV on why?
A researcher conducts a study in which the population variance of difference scores between two groups is unknown. What type of t-test is most appropriate for this study? Question 6 options: one–independent sample t-test two–independent sample t-test related samples t-test There is not enough information to answer this question.
A researcher is using a two-tailed hypothesis test with α = .05 to evaluate the effect of a treatment. If the boundaries for the critical region are t = ± 2.080, then how many individuals are in the sample? n = 20 n = 22 n = 21 Impossible to determine without more information
The scenario is as follows You are an IO psychology researcher, and you have developed a new type of employee training program. You conduct an experiment in which you administer the training program to one group (treatment group) and do nothing to the other group (control group). You then give each group a task to complete. The training program was developed to improve performance on the experimental task; as a researcher, then, you expect the treatment group to perform better...
Post an example of a scenario that would warrant either a one-sample or a two-sample test. This can be a hypothetical example. Please state H0 and H1 and explain why your hypothetical example qualifies as either a one- or two-sample test. (Please recognize that one- and two-sample tests are not the same as one- or two-tail tests.) Also, clearly state the reason(s) this hypothesis test would be conducted. You do not actually have to complete the hypothesis test steps.
A researcher is interested in whether a person’s gender is related to their favorite subject in school. The researcher records how many male and female participants are in the study and whether they prefer English, Math, or Science. A. What type of study design is this (descriptive, correlational, or experimental)? B. What would be the appropriate statistical analysis to use in that situation (Chi-Square, Pearson correlation, one sample t-test, paired samples t-test, independent samples t-test, or ANOVA)?
3. A researcher is interested in comparing the average self-esteem scores between college educated adults and non-college educated adults. She collects a sample from each population to be in the study, which of the following tests would be appropriate for this analysis? i. Paired t test ii. Correlation Independent Samples T test iv. One Sample t test iii.
