APAKAH MAKSUD FALSE NEGATIVE dalam CORSICA?
Jenis I dan kesilapan jenis II
Dalam statistik, hipotesis nol adalah pernyataan bahawa perkara yang dipelajari tidak menghasilkan kesan atau tidak memberi perbezaan. Contoh hipotesis nol adalah pernyataan "Makanan ini tidak memberi kesan kepada berat badan manusia." Biasanya seorang pengeksperimen bingkai hipotesis nol dengan niat menolaknya: iaitu, berhasrat untuk menjalankan eksperimen yang menghasilkan data yang menunjukkan bahawa perkara yang di bawah kajian membuat perbezaan. Kesalahan jenis I ialah penolakan salah hipotesis nol sebenar. Berkenaan dengan hipotesis yang tidak nol, ia mewakili positif yang salah. Biasanya kesalahan jenis I mengarahkan seseorang untuk membuat kesimpulan bahawa kesan atau hubungan yang sepatutnya berlaku apabila sebenarnya tidak. Contoh kesilapan jenis I termasuk ujian yang menunjukkan pesakit mempunyai penyakit apabila pada hakikatnya pesakit tidak mempunyai penyakit, penggera kebakaran akan berlaku yang menunjukkan kebakaran apabila sebenarnya tiada api atau eksperimen menunjukkan bahawa rawatan perubatan harus menyembuhkan penyakit apabila sebenarnya tidak. Kesalahan jenis II ialah kegagalan untuk menolak hipotesis nol palsu. Berkenaan dengan hipotesis yang tidak nol, ia mewakili negatif palsu.
