Tanlashdan oldin — saralang

52-darsda gipotezani X → Y shaklida nomlashni o'rgandik. Endi variantlar bilan ishlashning eng tez usulini qo'shamiz.

Ko'p o'quvchi to'rt variantni o'qib, «qaysinisi eng yaxshi?» deb solishtiradi. Bu sekin va xato. Tezroq yo'l: har variantni uch qutidan biriga tashlang, ketma-ket, solishtirmasdan.

QutiSinov savoli
KUCHAYTIRADIBu rost bo'lsa, gipotezaga ishonchim ortadimi?
KUCHSIZLANTIRADIBu rost bo'lsa, ishonchim kamayadimi?
TEGMAYDIRost bo'lsa ham, X → Y strelkasi o'zgarmaydimi?
📌 Eslatma: Amalda variantlarning ikki yoki uchtasi uchinchi qutiga tushadi. Ya'ni bu savol turi ko'rinishidan qiyin, aslida esa ko'pincha bitta haqiqiy raqobatchi bo'ladi — faqat siz uni topa olishingiz kerak.
⏱ ~70 soniya

«Tegmaydi» qutisining uch ko'rinishi

1. Fon fakti. Mavzu haqida rost gap, lekin gipotezaning strelkasiga aloqasi yo'q («chumolilar Janubiy Amerikada uchraydi»).

2. Matnning takrori. Matn allaqachon aytgan narsa. Yangi ma'lumot bo'lmasa, u gipotezaga hech nima qo'shmaydi — «if true» degani yangi topilma degani.

3. Ikki tomonga ham yaraydigan. Gipoteza to'g'ri bo'lsa ham, noto'g'ri bo'lsa ham kutiladigan narsa. Bu eng nozigi: u dalilga o'xshaydi, lekin hech nimani ajratmaydi.

⚠️ Tuzoq: Uchinchi ko'rinish uchun oddiy sinov bor: «gipoteza noto'g'ri bo'lganda ham shu topilma bo'lishi mumkinmi?» Javob «ha» bo'lsa — u dalil emas. Qal'a devorlari ikki marta ta'mirlangani doimiy yashash uchun ham, vaqtinchalik boshpana uchun ham bir xilda kutiladi.

Ishlangan namuna — to'rttasini ham saralaymiz

Nurses on a ward were asked to wash their hands at a sink placed beside the door, and compliance was measured at under half of opportunities. After a second sink was installed in the middle of the ward, compliance rose to nearly four fifths. The ward manager concluded that the original failure was a matter of distance rather than of attitude: staff had not been unwilling, only far away.

Which finding, if true, would most directly support the manager's conclusion?

  1. Handwashing compliance on the ward is now higher than the hospital average.
  2. On the three wards where a second sink was later added, compliance rose by a similar amount, and on the two where staff attended a hygiene talk instead, it did not.
  3. Nurses on the ward reported that they understood the importance of handwashing.
  4. The new sink was installed during a week when the ward was unusually quiet.

Yechim — saralash

Gipoteza: masofa (X) → qo'l yuvmaslik (Y). Munosabat emas, masofa.

Endi har variantni qutiga tashlaymiz — solishtirmasdan:

TO‘G‘RIOn the three wards where a second sink was later added, compliance rose by a similar amount, and on the two where staff attended a hygiene talk instead, it did not — KUCHAYTIRADI. Ikki tomonlama: rakovina qo'shilgan joyda o'sish bor, munosabatga ta'sir qiladigan chora (suhbat) qo'llangan joyda esa yo'q. Bu gipotezaning «masofa, munosabat emas» degan aniq da'vosini sinaydi.
TUZOQHandwashing compliance on the ward is now higher than the hospital average — TEGMAYDI (fon fakti). Boshqa bo'limlar bilan solishtiruv yangi ko'rsatkich beradi, lekin o'sishning sababi haqida hech nima demaydi.
TUZOQNurses on the ward reported that they understood the importance of handwashing — TEGMAYDI (ikki tomonga ham yaraydigan). Ahamiyatni tushunish — masofa nazariyasida ham, munosabat nazariyasida ham kutiladi: munosabat muammosi bilim yetishmasligi degani emas.
TUZOQThe new sink was installed during a week when the ward was unusually quiet — KUCHSIZLANTIRADI. Bu muqobil tushuntirish beradi — balki o'sish tinch haftadan. Savol support so'ragan, demak bu javob emas; lekin uni «aloqasiz» deb tashlab yubormang — uni to'g'ri qutiga solish muhim.
💡 Maslahat: Saralash tugagach hisob shunday chiqdi: 1 kuchaytiradi · 1 kuchsizlantiradi · 2 tegmaydi. Savol support so'ragani uchun javob o'z-o'zidan qoldi — hech qanday solishtirish kerak bo'lmadi. Bu usulning butun foydasi shunda.

Fireflies in a valley flash in unison for part of each summer night. A researcher proposed that the synchrony arises without any leader: each insect simply shifts its own rhythm slightly toward the flashes it sees nearby, and with enough insects doing this the whole valley falls into step.

Which finding, if true, would most directly support the researcher's proposal?

Shops that play slow music report that customers stay longer and spend more. A consultant concluded that the tempo itself slows customers' movement through the shop, and recommended slow music to retailers generally.

Which finding, if true, would most directly weaken the consultant's conclusion?

A museum found that visitors spent longer at objects displayed alone in a case than at objects displayed in groups of six or more. The curator concluded that isolation signals importance, and that visitors read the display as an instruction about where to look.

Which finding, if true, would most directly weaken the curator's conclusion?

Villages that installed a communal water pump saw childhood illness fall over the following two years. Two explanations were offered: that the pump water was cleaner than the river water it replaced, and that families no longer spent hours a day carrying water and could spend the time on other things. The engineers who ran the programme concluded that the water quality was doing the work.

Which finding, if true, would most directly support the engineers’ conclusion?

Xulosa

  • Solishtirmang — saralang: kuchaytiradi · kuchsizlantiradi · tegmaydi.
  • Odatda ikki-uchtasi tegmaydi qutisiga tushadi.
  • «Tegmaydi» ning uch ko'rinishi: fon fakti · matnning takrori · ikki tomonga ham yaraydigan.
  • Sinov: «gipoteza noto'g'ri bo'lganda ham bu topilma bo'lardimi?» Ha bo'lsa — dalil emas.
  • Kuchsizlantirishning eng ko'p shakli: ikki guruh yana bir jihat bilan ham farq qilardi.
