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…

Does data reduction and balancing the target variable eliminate skewness?

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…

Examination of large data sets to uncover hidden patterns is often referred to as:    Data analytics, Analysis review procedures, Test of controls, Artificial analytical review

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…

Because statistical software plays such an important role in modern statistical applications, many studies have encouraged the use of technology in statistics courses. The Guidelines for the Assessment and Instruction in Statistics Education (GAISE) (Aliaga et al., 2005) project was funded by the American Statistical Association to examine needs for college level statistics courses. One of the six recommendations from GAISE is the use of technology for developing conceptual understanding and analyzing data. A survey was sent to students at 100 different universities across the United States to access the relationship between ease of learning the statistical software program SAS and a student's currently level of SAS proficiency. The results of the survey are published in Jackson et al., 2011, in the International Mathematical Forum journal and are shown below. Table 1.Two-way table for ease of learning SAS and SAS proficiency level. Proficiency Not Somewhat Total Very proficient…

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…
