Rumus untuk angket berbentuk kuesioner: Σ Skor PR =
X 100 % Σ Responden X Σ Item X Skala tertinggi
Untuk tes digunakan rumus: Skor rata-rata PR =
X 100% Skor maksimum
B. Hasil Perhitungan 1. Variabel Strategi Membaca (X1) Σ Skor = 10457 Σ Item = 30
Σ Responden = 84 Skala tertinggi = 5

10457 PR =
X 100 % 80 X 30 X 5i
= 82,9% (Kategori Baik)
2. Variabel Penguasaan Kosakata (X2) Skor Rata-rata = 66,46 Skor Maksimum = 83 Skor rata-rata PR =
X 100% Skor maksimum
= 66,46 X 100% 83 = 80,07% (Kategori Baik)
3. Variabel Kemampuan Membaca Alinea (Y) Skor Rata-rata = 77,25 Skor Maksimum = 95 Skor rata-rata PR =
X 100% Skor maksimum
= 77,25 X 100% 95 = 81,31% (Kategori Baik)
