how is the statment a good example of why qualitative methodologie is more valuable in advancing cross-cultural research? I think qualitative methodologies are very valuable in advancing cross-cultural research. Qualitative methodologies are used in cross-cultural research by cultural anthropologist for what are called ethnographies. Ethnographies involve observation and field-work within the cultural context and require descriptive qualitative analysis. Some of the advantages of studies involving two or three countries compared to studies that involve ten or more countries are a more concentrated and have a smaller study group. Another advantage is being able to report various cultural variables as it relates to the study and qualitative data. A few disadvantages of studies involving two or three countries compared to involving ten or more countries are the potential for inaccurate results if it does not include the entire population. Another disadvantage of three countries in a study…

Question The question is the bottom of the page. See the figure attached to this question. Scenario 9.1 is based on and presents results consistent with the following studies: Snedeker, J., Geren, J., & Shafto, C. L. (2012). Disentangling the effects of cognitive development and linguistic expertise: A longitudinal study of the acquisition of English in internationally-adopted children. Cognitive Psychology, 65(1), 39–76. doi:10.1016/j.cogpsych.2012.01.004 Snedeker, J., Geren, J., & Shafto, C. L. (2007).

Psychological Science, 18(1), 79–87. doi:10.1111/j.1467-9280.2007.01852.x Language development occurs in orderly stages, beginning with one-word utterances and progressing to two-word utterances, simple sentences containing function morphemes, and the emergence of grammatical rules. Psycholinguists have attempted to determine if language development is a consequence of cognitive development…

How can surveys be used to address descriptive and/or causal research questions? What are some of the advantages of using surveys to collect data? What about the disadvantages?

Absenteeism:  Absenteeism can be a serious employment problem.  It is estimated that absenteeism reduces potential output by more than 10%.  Two economists launched a research project to learn more about the problem.  They randomly selected 100 organizations to participate in a 1-year study.  For each organization, they recorded the average number of days absent per employee and several variables thought to affect absenteeism. Management’s goal here is to analyze the data and determine which factors may be helpful in predicting absenteeism. Perform a two-sample t-test analysis to determine if mean absenteeism is different between organizations which have a good Union management and those that do not. I have provided the F-test for two variances below: Copy and paste the Two sample t-test output below AND provide a clear conclusion supported by key statistics in the output about how absenteeism is affected by the Union Management Relationship. (I just need to know how to perform the two…

Now let us build a model to predict absenteeism based on key independent variables available in this dataset; wage, PctPT, PctU, Av Shift and U/MRel. Correlation matrix is provided below. Why are the variables AvShift and U/MRel excluded from this correlation matrix?  Which variable in the matrix is likely to provide the best simple linear regression model and why? Does the correlation matrix show any evidence of collinearity? Explain.    Data:…

Case study The board of a large Australian investment bank of 7,200 employees (1,800 females and 5,400 males) has received media criticism over its poor record on employee work-life balance. It is looking to implement a range of workforce strategies and wants to survey its employee base to see how that might best improve. The company is headquartered in Melbourne, with equally-sized offices in Sydney, Brisbane and Perth. Some variables of interest in the proposed survey include: Variable Department ID Age Number of dependants Desire to work-from-home (WFH) preference Description Randomly generated 5-digit number for each of the company's 42 departments, which also identifies the department's location In years Scale from 'Highly undesirable' to 'Highly desirable' a) For each of the variables mentioned in the table above, determine whether they are nominal, ordinal or quantitative. Furthermore, for variables that are quantitative, also determine if the variable is likely to be discrete…

Learning math The Core Plus Mathematics Project (CPMP) is an innovative approach to teaching Math-ematics that engages students in group investigations and mathematical modeling. After field tests in 36 highschools over a three-year period, researchers comparedthe performances of CPMP students with those taughtusing a traditional curriculum. In one test, students had tosolve applied Algebra problems using calculators. Scoresfor 320 CPMP students were compared to those of a control group of 273 students in a traditional Math pro-gram. Computer software was used to create a confidence interval for the difference in mean scores. (Journal forResearch in Mathematics Education, 31, no. 3[2000])Conf level: 95% Variable: Mu(CPMP) – Mu(Ctrl)Interval: (5.573, 11.427)a) What’s the margin of error for this confidenceinterval?b) If we had created a 98% CI, would the margin of errorbe larger or smaller?c) Explain what the calculated interval means in context.d) Does this result suggest that students…

Part I - ANOVA An experiment was conducted to determine if motivational techniques in management significantly affected employee stress levels compared to no intervention.  An employee survey was given to three groups: one group under a manager who started using a transformational motivation technique, one group under a manager who began using a transactional motivation technique, and then a control group with no new technique used.  Stress levels were self-reported by the employees on 10-point Likert scales (0 – no stress, 1- little stress, 9 – very high stress). The results are shown below. Use alpha = 0.05. Transformational Transactional Control 0 2 6 7 5 5 3 3 8 5 0 9 2 1 5   Explain why using ANOVA is appropriate for this data. What assumptions need to be addressed to use this type of test? What is your null hypothesis and alternative hypothesis?   After running the single factor analysis of variance (ANOVA) on the data,…

"Bullying." according to noted expert Dan Olweus, "poisons the educational environment and affects the learning of every child." Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure depression in a group of victims and a group of bully-victims using a 26-item, 3-point depression scale. Assume scores on the depression scale are normally distributed and that the variances of the depression scores are the same among victims and bully-victims. The group of 25 victims scored an average of 25.3 with a sample standard deviation of 9 on the depression scale. The group of 23 bully-victims scored an average of 20.5 with a sample standard deviation of 8 on the same scale. You do not have any presupposed assumptions about whether victims or bully-victims…
