Jadi UMVU merupakan penduga tidak bias yang

memiliki ragam terkecil diantara semua penduga

tidak bias lainnya, dan sifat ini berlaku untuk semua

kemungkinan nilai parameter.

Istilah lain bagi UMVU adalah minimum variance

unbiased estimator (MVUE).

Persoalan berikutnya adalah bagaimana cara

memperoleh penduga yang bersifat UMVU ini.

Hal ini akan dibahas pada materi-materi

selanjutnya.
