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…

5. Effect size for independent-measures t test - Cohen's d and r squared Tobacco companies have actively attempted to remake their public image by launching a youth smoking prevention advertisement campaign. Melanie Wakefield (a professor of applied psychology and researcher at the Center for Behavioral Research in Cancer in Victoria, Australia) and her colleagues conducted a study to assess the relation between exposure to tobacco companies' youth smoking prevention advertising and youth smoking-related beliefs, intentions, and behaviors. You use Professor Wakefield's research to design an experiment with two groups of middle school students from Morocco. You show the tobacco company's youth smoking prevention ads to one of the groups of students every day for a week at the beginning of their math class. After the week, you assess the groups on the degree to which the students approve/disapprove of adults smoking, using a 5-point Likert scale. You do not have a prediction about the…

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. 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 The following down below is the correlation matrix between absenteeism and potential independent variables. 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…

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.

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…

Is Data analysis methods: description of the data analysis methods is clear and appropriate? Thematic analysis was utilized in which themes from the data of the interviews, questionnaire, and phone call were identified by grouping similar answers into larger categories. Major themes emerged in the process of grouping. These themes were then organized into minor themes. Open coding, or initial coding was utilized for the data where fragments of data such as keywords, incidents, etc. were studied closely for analytic import. "Initial coding continues the interaction that you shared with your participants while collecting data but brings you into an interactive analytic space (Silipigni Connaway, L., &, Radford, M. L., 2021). The software that seemed best for the study that was used was MicroCase, a statistical analysis and data management system, as it developed with social science researchers in mind to utilize, and the area of workplace ageism as derived from social interaction…

What is the observational study design used in the study   Objective: We evaluated the associations of long-term changes in consumption of sugary beverages (including sugar-sweetened beverages and 100% fruit juices) and artificially sweetened beverages (ASBs) with subsequent risk of type 2 diabetes.   Research design and methods: We followed up 76,531 women in the Nurses' Health Study (1986-2012), 81,597 women in the Nurses' Health Study II (1991-2013), and 34,224 men in the Health Professionals' Follow-up Study (1986-2012). Changes in beverage consumption (in 8-ounce servings/day) were calculated from food frequency questionnaires administered every 4 years.   Results: During 2,783,210 person-years of follow-up, we documented 11,906 incident cases of type 2 diabetes. After adjustment for BMI and initial and changes in diet and lifestyle covariates, increasing total sugary beverage intake (including both sugar-sweetened beverages and 100% fruit juices) by >0.50 serving/day over a…

Early-Onset Dementia. Dementia is the loss of the intellectual and social abilities severe enough to interfere with judgment, behavior, and daily functioning. Alzheimer’s disease is the most common type of dementia. In the article “Living with Early Onset Dementia: Exploring the Experience and Developing Evidence- Based Guidelines for Practice” (Alzheimer’s Care Quarterly, Vol. 5, Issue 2, pp. 111–122), P. Harris and J. Keady explored the experience and struggles of people diagnosed with dementia and their families. A hypothesis test is to be performed to decide whether the mean age at diagnosis of all people with early-onset dementia is less than 55 years old. a. determine the null hypothesis. b. determine the alternative hypothesis. c. classify the hypothesis test as two tailed, left tailed, or right tailed.
