Regression analysis of Complex Sample Survey Data: results from a national survey

This study made comparison if there are differences in mean and sig- nificant probability depending on application method of weights when chi- square test is performed using Complex Sample Survey Data. Multiple regres- sion and complex sample regression analysis were used as analyzing methods. Youth Risk Behavior Web-based Survey (KYRBS) 2012 was used as data source. As the result of multiple regression and complex sample regression analysis, there were differences in mean and significant probability. The result of this study confirmed that in the analysis of data from complex sample survey, biased variance (standard error) may be drawn out when using Simple Random Sampling Design.
