MODEL ANALISA VALIDITAS
/MODEL ANALSISA SOAL DENGAN STATISTIKA
PROGRAM SPSS16.0
PRESENTED BY OKY WJ
Saya ucapkan terimakasih banyak atas dosen statistika dan komputer saya, yaitu pak Irianton Aritonang. Dan ini saya buat supaya ilmu dari beliau bisa di share kemana mana. Dan saya minta maaf dan mohon kritikan jika dalam interprestasi di bawah yang saya kemukakan ada kesalahan. Saya mohon kritikan dari para pembaca semua. Semoga kita bisa lebih maju dengan pola pikir yang lebih baik. Amin… salam pelajar Indonesia. Ayo semangat untuk maju.. SEMOGA BERMANFAAT. Untuk kritik kirim ke email : [email protected]
Buat variable terlebih dahulu seperti diatas dengan tampilan variable view pada spss 16.0
Di “value” beri dua pilihan “0 untuk jawaban salah” dan “1 untuk jawaban benar”
Agen 1 sampai 6 jangan dibuat dahulu. Itu bisa menggunakan vasilitas menu “transform, computer variable” seperti langkah di lembar berikut ini.
Isikan data dengan tampilan data view seperti di atas.”0 untuk jawaban salah, dan 1 untuk jawaban benar”
Buat agen 1 sampai agen 6 dengan langkah seperti di atas, dan penamaan bisa beda. Tidak harus agen, alias terserah anda bung. Cara input datanya ditampilkan di lembar berikutnya.
Di atas adalah cara input nya. Jadi agen 1 saya beri soal no 1 ‐6, agen 2 no 7‐14, agen 3 no 15‐20, agen 4 no 21 – 27, agen 5 28 ‐34, dan agen 6 no 36 ‐40. Pembagian ini terserah anda bung.
Ini adalah model pembagian tadi yang saya bicarakan di atas.
COMPUTE AGEN1= SOAL1 + SOAL2 + SOAL3 + SOAL4 + SOAL5 + SOAL6. EXECUTE. COMPUTE AGEN2=SOAL7 + SOAL8 + SOAL9 + SOAL10 + SOAL11 + SOAL12 + SOAL13 + SOAL14. EXECUTE. COMPUTE AGEN3=SOAL15 + SOAL16 + SOAL17 + SOAL18 + SOAL19 + SOAL20. EXECUTE. COMPUTE AGEN4=SOAL21 + SOAL22 + SOAL23 + SOAL24 + SOAL25 + SOAL26 + SOAL27.
EXECUTE. COMPUTE AGEN5=SOAL28 + SOAL29 + SOAL30 + SOAL31 + SOAL32 + SOAL33 + SOAL34. EXECUTE. COMPUTE AGEN6=SOAL35 + SOAL36 + SOAL37 + SOAL38 + SOAL39 + SOAL40.EXECUTE.
Langkah analisa bisa bung lakukan seperti di atas.
Ini tampilan selanjutnya dan bung bisa analisa tiap pembgian soal tadi sesuai pembagian agen tadi. Di sini yang saya tampilkan hanya cara analisa soal no 1‐6, tetapi untuk semua hasil analisa saya tampilkan semua yang ada di bawah / lembar selanjutnya bung.
Klik satistik untuk memunculkan apa saja yang mau ditampilkan dari hasil analisa bung.

Tabel di atas digunanak untuk mengetahui keeratan hubungan tiap soal. Apakah antara soal 1
dengan soal ke dua memiliki hubungan erat atau tidak. Dikatakan erat jika haril perpotongan
tabel di atas menunjukkan nilai mendekati 1 bahkan 1. Yang memiliki korelasi kuat akan
saya beri warna merah pada tabel di atas. Lihat warna merahnya gan. Apa interprestasi
anda… :D

AGEN1 5.0312 .999 1.000 . .286
Tabel di atas ini digunkan untuk menentukan apakah soal tersebut valid atau tidak valid.
Caranya lihat tabel “r pearson”, lihat yang dua sisi kemudian lihan yang dua sisi “two-side”,
lalu lihat tingkat kepercayaan anda. Di spss default 95 %, maka alfa adalah 5% (0,05). Hasil
dari pembacaan tabel adalah 0,2050 . Kemudian lihat hasil dari “Corrected Item-Total Correlation”.
Jika hasilnya ada yang di bawah angka 0,2050 maka bisa dikatakan tidak valid / tipe soal kurang valid.
!!!!! sesungguhnya valid atau tidak sangat dipengaruhi oleh banyaknya N/ sample yang anda gunakan……
