1. Jelaskan pengertian The Weighted mean dan Geometric mean! Sertakan contohnya! a. Weighted Mean : Rata-rata yang dihitung dengan memperhitungkan bobot setiap datanya. Setiap bobot tersebut merupakan pasangan setiap data. Contoh : Pada tes penerimaan mahasiswa baru di suatu PTN, siswa harus mengikuti ujian masuk yang terdiri dari 3 pelajaran: Tes kemampuan IPA, Tes Kemampuan Dasar (TKD), dan Tes Potensi Akademik (TPA). Agar penilain lebih baik, setiap mata pelajaran yang diujikan diberi nilai bobot: 50 untuk kemampuan IPA, 30 untuk TKD, dan 20 untuk TPA. Setelah ujian dilaksanakan, seorang siswa mendapat nilai: 65 untuk Kemampuan IPA, 70 pada TKD, dan 80 pada TPA. Setelah di rata-rata, nilai siswa tersebut menjadi: ´ x = ( 65 × 50 ) + ( 70 × 30 ) +( 80 × 20 ) 50 + 3 + 20 = 6950 100 = 69,5 b. Geometric Mean : rata-rata yang diperoleh dengan cara mengalikan semua data dalam suatu kelompok sampel, kemudian data tersebut di- akar-pangkatkan dengan banyaknya data. Contoh : Suku bungan tabungan beberapa bank adalah: 6,75; 5,75; 6,5; 6,25; 6,25; 6,10; 5,70; 5,90; 5,60 Cara 1 G = 10 6,75 × 5,75 ×…× 5,56 = 10

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
