t tabel
2,0423
Untuk df = 30 dan α = 0,05 uji dua sisi, nilai t tabel adalah 2,0423. H₀ ditolak jika |t hitung| > 2,0423.
Apa itu t tabel?
t tabel adalah nilai kritis dari distribusi t Student. Nilai ini menjadi batas untuk memutuskan apakah hasil uji t signifikan. Kalau nilai mutlak t hitung lebih besar dari t tabel, H₀ ditolak.
t tabel dipakai di banyak analisis skripsi:
- Uji t satu sampel: membandingkan rata-rata dengan nilai tertentu.
- Uji t sampel berpasangan, misalnya nilai pretest dan posttest.
- Uji t sampel independen, misalnya kelas eksperimen dan kelas kontrol.
- Uji t parsial dalam regresi: menguji pengaruh tiap variabel bebas secara terpisah.
Menentukan derajat bebas (df)
| Analisis | Rumus df |
|---|---|
| Uji t satu sampel | |
| Uji t berpasangan | (n = jumlah pasangan) |
| Uji t sampel independen | |
| Uji t parsial regresi | (k = jumlah variabel bebas) |
| Uji signifikansi korelasi |
Cara membaca tabel t
- Hitung df sesuai jenis analisis (lihat tabel di atas).
- Tentukan α dan arah uji. Umumnya α = 0,05 uji dua sisi.
- Cari pertemuan baris df dan kolom α. Baris judul putih untuk uji dua sisi, baris judul kuning untuk uji satu sisi.
- Bandingkan: H₀ ditolak bila (uji dua sisi).
Contoh: uji t parsial regresi
Penelitian dengan 100 responden dan 3 variabel bebas (promosi, harga, kualitas layanan) terhadap minat beli.
- , , uji dua sisi, sehingga .
- Variabel promosi memiliki . Karena , promosi berpengaruh signifikan secara parsial.
- Variabel harga memiliki . Karena , pengaruh harga tidak signifikan.
Kesalahan umum
- Memakai untuk semua jenis uji. df berbeda untuk tiap analisis.
- Membandingkan t hitung yang negatif tanpa nilai mutlak pada uji dua sisi.
- Memakai kolom satu sisi untuk hipotesis yang tidak berarah.
- Menyimpulkan "tidak ada pengaruh sama sekali" dari hasil yang tidak signifikan. Yang tepat: belum cukup bukti adanya pengaruh.

Pertanyaan umum
Berapa t tabel untuk df 30 dan α 0,05?
Untuk uji dua sisi, t tabel = 2,0423. Untuk uji satu sisi, t tabel = 1,6973.
Bagaimana menentukan df untuk uji t parsial di regresi?
df = n − k − 1, dengan n jumlah sampel dan k jumlah variabel bebas. Contohnya, regresi dengan 100 responden dan 3 variabel bebas memakai df = 96, sehingga t tabel (α = 0,05, dua sisi) = 1,9850.
Bagaimana mencari t tabel di Excel?
Untuk uji dua sisi gunakan =T.INV.2T(alpha; df), misalnya =T.INV.2T(0,05; 30) menghasilkan 2,0423. Untuk uji satu sisi gunakan =T.INV(1−alpha; df).
Mengapa t tabel untuk df besar mendekati 1,96?
Semakin besar df, distribusi t semakin mirip distribusi normal baku. Untuk df = 1000 dan α = 0,05 dua sisi, t tabel = 1,9623, sangat dekat dengan z tabel 1,9600.
