Interval Kepercayaan yang sering ju

Interval Kepercayaan yang sering juga disebut Margin of error merupakan tingkat kepercayaan yang ditentukan berdasarkan ukuran sampel yang kita inginkan. Sedangkan dalam Sundari (2014) dijelaskan bahwa confidence interval adalah sebuah interval yang berdasarkan observasi sampel dan terdapat probabilitas yang ditentukan. Dimana interval mengandung nilai parameter sebenarnya yang tidak diketahui. Perhitungan dalam confidence interval umumnya menggunakan kemungkinan 95% nilai sebenarnya. Adapun persamaan yang digunakan dalam menghitung confidence interval sebagai berikut

The confidence interval is often also called the Margin of error is determined based on the degree of confidence that the sample size we want. Whereas in Sundari (2014) explained that the confidence interval is an interval based on the observation of a sample and there is a probability that is specified. Where the interval contains the actual parameter values are not known. In the calculation of confidence intervals 95% chances are generally use the actual values. As for the equation used in calculating confidence intervals as follows
