ISO 9001:2008 - Certificate: HU11/6195 Methodology Control The control procedures used in every stage of the research guarantees the validity of the research results: * When choosing the sampling procedure and when deciding the largeness of the sample, we report the largeness of the error of the sampling in every case. * In the case of trial questions, we reveal the possible mistakes of the finished questionnaire (misunderstood question, refused to answer, etc.). * Our interviewers are individually prepared for each and every research project. * The work of our interviewers is monitored with 100% supervision. * Each questionnaire goes through a logic supervision consisting of many different point of views. Sampling Control The choosing of the proper sampling method and the proper largeness of the sample will in advance determine the cost and the use of the research: If the largeness of the sample is too small, then it not possible to obtain a generalization of the results. If the largeness of the sample is too big, then the price will be higher. Data Analysis Control Since we typically work with small samples, because of the characteristics of our groups, we place a large emphasis on the use of the most modern, processed statistic procedures which are specialized for the research of small samples. Naturally, our company has succeeded in marketing research up to this point and uses data analysis procedures which are widespread in a wide ring.
