Quantitative research Essay

Quantitative research is the research method because this research method can collect many opinions and information from the large audiences and it is easier in doing analysis. After that, numerical data that successfully collected in the quantitative research is closely related to the final part of the research. (http://www.sagepub.com/upm-data/36869_muijs.pdf)- journal In addition, quantitative research is helpful in explaining and analyzing about a specific topic. (http://www.sagepub.com/upm-data/36869_muijs.pdf) For example, for research title† The negative impact of violence drama toward teenagers violence behavior†, through the quantitative research, people can know that actually how many of the teenagers actually will curious about the violence drama? Or actually how many of them will get influences or imitate what shown in the violence drama? Lastly, quantitative research can also help to narrow the wide number of public opinion into quantitative through questionn aire or tests. Thus, as mentioned above, it is easier in doing analysis after all the information is being gathered. Definition of quantitative research, viewed by †¦. Weblink Sample There are two types of sampling, which are probability sampling and nonprobability sampling. Probability sampling refer to everyone has the chance to enroll in the sample and it can be defined accurately. (http://www.statcan.gc.ca/edu/power-pouvoir/ch13/nonprob/5214898-eng.htm). Possibility sampling shows the features of the chosen population and thus, it is more credibility. (http://psychology.ucdavis.edu/sommerb/sommerdemo/sampling/types.htm) However nonprobability sampling refer to just some of the people can enroll in the sample and it result cannot define accurately. (http://www.statcan.gc.ca/edu/power-pouvoir/ch13/nonprob/5214898-eng.htm) There are quota sample, purposive sample and convenience sample in the nonprobability sampling. Convenience sample (nonprobability sample) is being used in this research because this research only targeted teenagers and college students. In other words, not all the people can be selected as target audiences for this research. The reason that t he survey questions are available to 100 people is because this can helps to find out different opinions and also find out how different teenagers behave differently after  watching violence drama. In addition, if there are no limits the numbers of the respondents, it is impossible to get the final result since there may be thousands of the different opinions and answers out there. Thus, choosing 100 people to answer on these questionnaires can help to minimize the large number of audiences too. Lastly, questionnaire survey for this research had been made as web questionnaire and target audiences can answer the questions by just clicking into the web link. Teenagers and college students have been choose to answer these questionnaires according to the gender because different gender may bring out a different result as well. Variables Variables are any aspect that will change the result of the studies. Independent variable is the one which always affects dependent variables. In this study, the independent variable is the violence drama and dependent variable would be the teenagers and college students because the negative impact brought out by violence drama may influence them. Measurement Measurement is the process of gathering the quantitative data. In addition, it is also a process that covert the data into phenomena based on the particular rules. Variables can be measured by different kind of measurement scales. In this research, there are close-ended questions, likert scales, guttman scaling. Close-ended Questions. Close-ended question is the question that provides several answers to let respondents choose. Means that, close-ended question is also the question that contain multiple choices. (www.businessdictionary.com/definition/closed-questions.html). Denifition of close-ended questions, Viewed by †¦Ã¢â‚¬ ¦, Weblink For example: Question: Have you ever watched violence drama before? Please choose the answer below. Yes No Respondents require choosing one answer only and this is easier to get the result and opinion from them. Likert Scales Likert scales are the questions to test the respondents’ level of agreement and disagreement. In addition, it is also the non-comparative scaling techniques. For example: Please choose the answer below. Questions: Statement Strongly Disagree Disagree Agree Strongly Agree I think I will to imitate because curious of the action from violence drama Respondents are require to choose one answer only of above and this is easier to test their level of agreement and disagreement. Guttman Scaling Guttman scaling is the question that contain few choices of answers and let respondents to choose the satisfy answer among it. For examples: Please choose the answer below. Questions: How often do you watch violence drama? Everyday Twice a week Once a month Others:__________ Respondents are require to choose one answer only and this is easier to do the analysis. Techniques and Scoring The techniques used to calculate the data of these measurement scales. Close-ended Questions For example: Question: Have you ever watched violence drama before? Please choose the answer below. oYes oNo Scoring Scores Final percentage Yes 83 89% No 10 11% 100% Table above showed the sample scoring for close-ended questions. From the result above, stated that most of the respondents have ever watched violence drama before. This is easier to find out the result by analyzing out the data collected. Likert Scales For example: Please choose the answer below. Questions: Statement Strongly Disagree Disagree Agree Strongly Agree I think I will to imitate because curious of the action from violence drama Final Percentage Strongly Disagree 29% Disagree 38% Agree 26% Strongly Agree 7% 100% Table above showed the sample scoring for likert scales. By looking through this table, the level of agreement and disagreement of respondents can be seen. Guttman Scaling For examples: Please choose the answer below. Questions: How often do you watch violence drama? oEveryday oTwice a week oOnce a month oOthers:__________ Scoring Final Percentage Everyday 15% Twice a week 30% Once a month 29% Others 26% 100% Table above showed the sample scoring for guttman scaling. As the table showed, there are most of the respondents watch violence drama twice a week. However, there are only few respondents that answer others. The percentages make the data analysis easier. Procedure The very first step to start this research is to decide the research topic first. Then, the following things that need to decide after the research topic is research problem and objectives. After determining all of these, all the questionnaires will be drafted out according to the information that decided and gathered during the previous steps. After created the questionnaires, the questionnaires were made as a web questionnaire and send to the target audiences for answering. Lastly, the next step after this was to collect the data, calculate it out, and make a data analysis for it. Thus, the first step is always important in doing a research as all the progress will be affected if the first step was doing in a wrong way. Conclusion As a conclusion, questionnaires are very important in getting an accurate result. Thus, when deciding the questionnaire, it is necessary to make sure the questionnaires are asking in a right way and logical way. If the questionnaires have a lot of mistakes, this will influence the final results and accurate data and information could not be collected.
