Abstract: <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> Spatial data is a collection of data based on the location where the measurement taken. To analyze spatial data, the method from Krige, called kriging, usually is <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> applied. In this thesis, this method is adopted to analyze the average of National Test Score from students in 36 vocational high schools located in Bandar Lampung. To get a kriging model, a semivariogram model is needed as an information to calculate the parameters in kriging model. For this case, the observation gives a spherical semivariogram model. In practice, kriging model is to estimate, by interpolation, the value of new selected location, around observed location. In here, this method is modificated. Kriging is applied to n-1 data, where <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> n is the total number of data. To evaluate the result, estimation from kriging is compared to the real value by a true statistic test Q.
