The Apply Research Of Multivariate Statistical Analysis In The Improving Effectiveness Of User Research

With the arrival of the era of experience economy, the experience of the user-centered design has become an important research direction in the process of product development and design. In order to improve the accuracy of user research and effectiveness, and provide direction for developing products, this study was based on the theory of multivariate statistical method theory. Through the analysis of the user survey data, this paper put forward user research model based on multivariate statistical analysis.The article reviewed the content of multivariate statistical theory and application status. Then the paper focused on the theory of factor analysis, cluster analysis and multiple linear regression theory. On the other hand, based on the theory of user research, the main contents of the user study and the methods of analysis were summarized, the application of multivariate statistical theory of innovation combined with user research were presented.Based on the proposed multivariate statistical validity in ascension user research point of application, we built three models. Such as model of users difference analysis based on factor analysis, model of user clustering based on cluster analysis and model of the use of the will analysis based on multiple linear regression. These models can be applied to different user studies.Considering the development of Internet technology and the popularity of smart phones, we selected the mobile phone APP users as an example. In user difference analysis, questionnaire investigation based on user's lifestyle and the results were factor analysis, extracted eight main factors. Through fast clustering method for grouping users, users have eventually been divided into five categories. In the analysis of users intend, quoting the UTAUT model for the design principle of the survey questionnaire. All factors were weighted regression analysis size, to better guide the product development design.This study provided a more systematic research method of the user study. Through the application about multivariate statistical theory and user studies, improved the effectiveness of user research, to enhance the validity of the results.
