CHAPTER III RESEARCHMETHODOLOGY

A. Scope of Research

This study was conducted on 60 people users futsal shoes in eastern ciputat chosen as respondents in this study. The object of research was conducted on the product Specs brand futsal shoes.

B. Determine sample method

1. Population

According to Indriantoro and Supomo 2002: 115 population population are a group of people, events or things that have certain characteristics. Meanwhile, according to Sugiyono 2008: 90, the population is a generalization region consisting of, objects subjects that have certain qualities and characteristics defined by the researchers to be studied and then drawn conclusions. From the above understanding of the population referred to in this case is whole is a set of all elements that 58 became the object of research or investigation.

2. Sample

According to Indriantoro and Supomo 2002: 115 can be interpreted that the sample is partially the elements that are in the population. According Sugiyono 2008: 91, the sample is part of the number and characteristics possessed by this population. The exposure of the sample in this case is a part of the population studied, which is considered representative of the population in this study. Techniques for taking the sample data used sampling techniques. In determining the data to be studied, the sampling technique used is the non- probability sampling is a sampling technique that does not provide equal opportunity for each element or member of the population to be sampled. Respondent was done by using purposive sampling. The intended use of purposive sampling techniques in this study to obtain respondents who are consumers make the shift from other brand shoes to the shoe brand Specs. Sugiyono 2008: 102 quotes the opinion of Roscoe stating decent sample size in the study was between 30 to 500. Researchers took a sample of 60 respondents with consideration of the number of samples is a decent amount and facilitate in making the presentation of research results.

C. Methods of Data Collection

Methods of data collection in this study carried out by way of noting a small part of the population, or in other words the sample course record. 59 Data collection method called sampling. Sampling is a method of collecting data that are incomplete, meaning that does not cover the whole object of research population = universe but only a part of the population only, which only covers a sample taken from the population Supranto, 1997: 55. The data used in this research is quantitative data, which is data that form of numbers Supranto, 1997: 6. Meanwhile, according to Indriantoro and Supomo 2002: 12 quantitative data is the data showing the number or amount of something. Data obtained in this research is the primary data, that is data collected by an individual organization directly via its object Supranto, 1997: 6. Primary data from this study were obtained by providing questions to a sample of respondents to the study questionnaire or a list of questions related to the research. The samples of this study were taken using a non- probability sampling method, which is the method of purposive sampling samples intended. Samples aims are non-probability sample that conform to certain criteria. The criteria that have been established are the Specs futsal shoes ever make purchases of other brand products. Because of the sampling technique used is non-probability sampling, not everyone has the opportunity to be the respondent. Therefore, it needs to be asked questions filtering to filter the respondent. For the data in this study secondary data obtained by reading the literature related to the 60 research and through the Internet, and other secondary data. This study also used a Likert scale measuring agreement and disagreement of respondents in responses proposed the statement. Likert scale is a measurement with five response categories ranging from “strongly disagree” to “strongly agree”, which requires the respondents to indicate a degree of agreement or disagreement with each of a series of statements related to the stimulus objects. Maholtra, 2006:264 The score of questionnaire assessment figures resulted in this study is according to the Likert scale described in the methods used to measure attitudes, opinions, and perceptions of a person or group of persons on a social phenomenon Sugiyono, 2007: 96 A measurement of each variable in this research using Likert scale to measure attitudes, opinion and perceptions of individuals or groups social phenomena Sugiyono, 2009: 94 By using a Likert scale, the measurement variable is an indicator variable that will be outlined. Using a Likert scale of five 5 levels to express the attitude or the respondent’s answer as follows: 61 Table 3.1 Likert scale of five 5 levels Sugiyono, 2009: 94 No Range Weight 1 Strongly Agree SA 5 2 Agree A 4 3 Neutral N 3 4 Disagree D 2 5 Strongly Disagree SD 1
