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…

Light and exam performance. A study is designed to test the effect of light level on exam performance of students. The researcher believes that light levels might have different effects on males and females, so wants to make sure both are equally represented in each treatment. The treatments are fluorescent overhead lighting, yellow overhead lighting, no overhead lighting (only desk lamps). What is the response variable?  What is the explanatory variable?  What are its levels?  What is the blocking variable? What are its levels?

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:…

Do single-parent families tend to be more impoverished than families with two parents? In order to test if there is a relationship between family structure and family income level, family researcher studied a sample of 35 one-parent and 65 two-parent families in a particular city to determine whether their total family income fell below the poverty level. _________________________Family Structure____________________________ Total family Income               One Parent                  Two Parents                TOTAL Below poverty level                      24                                      20                        44     Not Below Poverty Level                                            11                                      45                         56 Total                                            35                                      65                        100 What are the independent and dependent variables.?

Can you please answer all of the questions about the information provided.  Background Previous studies have demonstrated the short-term efficacy of pharmacotherapy and behavior therapy for attention-deficit/hyperactivity disorder (ADHD), but no longer-term (ie, >4 months) investigations have compared these 2 treatments or their combination. A 1999 study conducted by MTA Cooperative Group conducted a multisite study designed to evaluate the leading treatments for ADHD.  The Study A group of 425 children with ADHD Combined Type, aged 7 to 11 years, were assigned to 14 months of medication management (titration followed by monthly visits); intensive behavioral treatment (parent, school, and child components, with therapist involvement, gradually reduced over time); or the two combined. Outcomes were assessed in multiple domains before and during treatment and at the treatment endpoint (with the combined treatment and medication management groups continuing medication at all assessment…

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…

variables and hypothesis section: The article reviews various aspects of network analysis and probabilistic inference to understand the complexities and dynamics of network analysis. It utilizes data from clinical education on diabetic foot and online social network software to analyze the relationships between network participants and the patterns related to their networking behavior. The data explored involve clinical education on diabetic foot and online and social network software for research. The variables being analyzed are the relationships between the network participants, as well as the patterns related to the networking behaviors. The hypotheses tested in the article are related to examining the effect of different forms of networks on the efficacy of clinical education, as well as the impact of online network relationships among people. The outcomes of the analysis and hypotheses in the article are used to explain the importance of different probabilistic inferences and…

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,…
