Question

PSY315 Week One Practice Problems;21. Raskauskas and Stoltz (2007) asked a group of 84 adolescents about their involvement in traditional and electronic bullying. The researchers defined electronic bullying as ??a means of bullying in which peers use electronics such as text messages, emails, and defaming Web sites to taunt, threaten, harass, and/or intimidate a peer? (p.565). The table below is a frequency table showing the adolescents? reported incidence of being victims or perpetrators or traditional and electronic bullying.;a. Using this table as an example, explain the idea of a frequency table to a person who has never had a course in statistics.;Frequency is how many times something has happened and of all of the possible results that can occur, and each result's respective chance of happening. So the frequency of the table would be how many times the vairiable occurred and are used to explain data gathered plus are a way to display certain factors existing. These tables are used to find the mean of a large set of data values.;b. Explain the general meaning of the pattern of results.;The general meaning of the pattern of results implies that;Incidence of Traditional and Electronic Bullying and Victimization (N=84);Forms of Bullying;N;%;Electronic victims;41;48.8;Text-message victim;27;32.1;Internet victim (websites, chatrooms);13;15.5;Picture-phone victim;8;9.5;Traditional Victims;60;71.4;Physical victim;38;45.2;Teasing victim;50;59.5;Rumors victim;32;38.6;Exclusion victim;30;50;Electronic Bullies;18;21.4;Text-message bully;18;21.4;Internet bully;11;13.1;Traditional Bullies;5;64.3;Physical bully;29;34.5;Teasing bully;38;45.2;Rumor bully;22;26.2;Exclusion bully;35;41.7;22. K?rn? and colleagues (2013) tested the effects of a new antibullying program, called KiVa, among students in grades 1?3 and grades 7?9 in 147 schools in Finland. The schools were randomly assigned to receive the new antibullying program or no program. At the beginning, middle, and end of the school year, all of the students completed a number of questionnaires, which included the following two questions: ?How often have you been bullied at school in the last couple of months?? and ?How often have you bullied others at school in the last couple of months?? The table below is a frequency table that shows students? responses to these two questions at the end of the school year (referred to as ?Wave 3? in the title of the table). Note that the table shows the results combined for all of the students in the study. In the table, ?victimization? refers to students? reports of being bullied and ?bullying? is students? reports of bullying other students.;a. Using this table as an example, explain the idea of a frequency table to a person who has never had a course in statistics.;Frequency is how many times something has happened and of all of the possible results that can occur, and each result's respective chance of happening. So the frequency of the table would be how many times the vairiable occurred and are used to explain data gathered plus are a way to display certain factors existing. These tables are used to find the mean of a large set of data values.;b. Explain the general meaning of the pattern of results. (You may be interested to know that the KiVa program successfully reduced victimization and bullying among students in grades 1?3 but the results were mixed with regards to the effectiveness of the program among those in grades 7?9.).;Frequencies of Responses in the Five Categories of the Self-Reported Bullying and Victimization Variables at Wave 3;Grades 1?3;Grades 7?9;Victimization;Bullying;Victimization;Bullying;Variable;Freq.;%;Freq.;%;Freq.;%;Freq.;%;Occurrence;Not at all;3,203;53.6;4,296;72;10,660;77.4;10,880;79.5;Only once or twice;1,745;29.2;1,333;22.3;2,031;14.7;1,987;14.5;2 or 3 times a month;446;7.5;197;3.3;402;2.9;344;2.5;About once a week;297;5;90;1.5;312;2.3;196;1.4;Several times a week;281;4.7;49;0.8;375;2.7;279;2;Participants;Respondents n;5,972;100;5,965;100;13,780;100;13,686;100;Missing n;955;962;2,723;2,817;Total N;6,927;6,927;16,503;16,503
