CHAPTER III RESEARCH METHODOLOGY

A. Scope of Research

This research is empirical study of research testing to prove the influence of service quality and promotion toward customers’ satisfaction. Scopes of research for this study are as follows: 1. The focus of the author in this study is the influence of service quality and promotion toward customers’ satisfaction. 2. The location and the objects to be examined are the customers of Lazada that located in www.lazada.co.id period June 2015. 3. For the purpose of the study, researcher employs customers’ satisfaction Y and service quality X 1 and promotion X 2 . B. Sampling Method 1. Population The population of this study covers the customers of Lazada Indonesia in the fashion segment. The reason why researcher chooses this population because the researcher wants to know the influence of service quality and promotion toward customers’ satisfaction of Lazada Indonesia. A population is the aggregate of all the elements that share some common set of characteristics and that comprise the universe for the purpose of marketing research problem, Maholtra, 2004: 314. Population is the generalization which consists of object and subject of a certain quantity and characteristics applied by researchers to learn and then drawn 35 the conclusion Population is subject or object which have certain qualities and characteristics are determined by researcher. Thus, the population is not only people but also objects or other natural objects. Population also not only quantity, but includes all of characteristics ’ subject or object Sugiyono, 2011:80. 2. Sample Samples are selected using non probability convenience sampling by means of sample units drawn easily be reached anywhere and anytime, is not troublesome to measure and cooperative Hamid, 2007: 30. Sample is a subject of the population that should represent that entire group. Or the sample is a subset of the population, and the sample unit pertains to the basic level of investigation Burns, 2005: 334. A sample is a member of the selected population using a specific procedure that is expected to represent its population Sugiyono, 2007:57. Sample is a subgroup of the elements of the population selected for participation in the study Maholtra, 2009:373. According to Cooper 2007:204 convenience sampling is non probability sampling where researcher use any radial available individuals as participants. The researcher takes 100 samples respondent, because according to Sugiyono 2010:74 guidelines to determining sample are as follows : a. Sample size should be between 30-500 elements. b. In the multivariate research multiple linear regressions the sample size should be several times larger 10 times than the 36 number of variables to be analyzed. c. A simple experiment for research, with strict controls, sample size between 10-20 elements.
