Psycholinguists have attempted to determine if language development is a consequence of cognitive development…arrow_forwardFriendship Motivation. In the article “Assessing Friendship Motivation During Preadolescence and Early Adolescence” (Journal of Early Adolescence, Vol. 25, No. 3, pp. 367–385), J. Richard and B. Schneider described the properties of the Friendship Motivation Scale for Children (FMSC), a scale designed to assess children’s desire for friendships. Two interesting conclusions are that friends generally report similar levels of the FMSC and girls tend to score higher on the FMSC than boys. Boys in the seventh grade scored a mean of 9.32 with a standard deviation of 1.71, and girls in the seventh grade scored a mean of 10.04 with a standard deviation of 1.83. Assuming that FMSC scores are normally distributed, determine the percentage of seventh-grade boys who have FMSC scores within a. one standard deviation to either side of the mean. b. two standard deviations to either side of the mean. c. three standard deviations to either side of the mean. d. Repeat parts (a)–(c) for seventh-grade…arrow_forward

- Social media provides an enormous amount of data about the activities and habits of people using social platforms like Face book and Twitter. The belief is that mining that data provides a treasure trove for those who seek to quantify and predict future human behavior. A marketer is planning a survey of Internet users in the United States to determine social media usage. The objective of the survey is to gain insight on these three items: key social media platforms used, frequency of social media usage, and demographics of key social media platform users. a. For each of the three items listed, indicate whether the variables are categorical or numerical. If a variable is numerical, is it dis crete or continuous? b. Develop five categorical questions for the survey. c. Develop five numerical questions for the survey.arrow_forwardAs you read about each study, (a) classify the type of research that it reflects, and (b) identify the kinds of conclusions that might reasonably be drawn from the results. During their 8th- and 11th-grade school years, students in the Ranger School District take standardized achievement tests designed to assess their language and math skills. The superintendent receives a report showing how Ranger students compare with those in many other school districts across the nation. The superintendent discusses the results with the school principals. (a) Classify the research as one of the following: Quantitative/descriptive Quantitative/correlational Quantitative/experimental Quantitative/quasi-experimental Qualitative Mixed methods, and then (b) Identify one or more conclusions that might reasonably be drawn from this study and, if relevant, one or more conclusions that cannot be drawn from the studyarrow_forward"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…arrow_forward
- The University of Michigan Health and Retirement Study (HRS) surveys more than 22,000 Americans over the age of 50 every two years. A subsample of the HRS participated in an Internet-based survey that collected information on a number of topical areas, including health (physical and mental health behaviors), psychosocial items, economics (income, assets, expectations, and consumption), and retirement. Two of the questions asked were: "Would you say your health is excellent, very good, good, fair, or poor?" and “Do you smoke cigarettes now?" Here is the two-way table that summarizes the answers on these two questions: Current smoker Нealth Yes No Excellent 25 484 Very good 115 1557 Good 145 1309 Fair 90 545 Рoor 29 11 This table gives the responses of a survey of 4310 Americans to questions about their health and whether they currently smoke cigarettes.

Less overt health implications may also occur within affected communities. The health consequences of mass shootings as well as violence, terrorism, and war disproportionately affect children because the periods of fetal development, infancy, and young childhood are especially sensitive to adverse shocks and stress. The purpose of this retrospective cohort study was to assess changes in newborn birthweight in U.S. communities where a mass shooting took place. Methods: This study ascertains whether exposure to a mass shooting in the county of birth adversely affected subsequent birthweight through community bereavement and stress. All births records from 1982-2002 in counties where a mass shooting took place were used; newborns were compared within-counties. A total of 3.2 million births were included in the analysis as well as 61…arrow_forwardWhat would be a easy suitable research design for this topic.
