Question

Accepted Answer

**Yanke shawara ta tushen bayanai** yana nufin wajeje zaɓin samfura a cikin shaida — bayanain amfani, gwaje-gwaje, bincike — maimakon ra'ayi kadai. Sautin girma shi ne *bayanai-bayani*: bayanai yana baka hankali, amma bai maye gurbin ba. Jiya shine rage haɗarin fida jiya kan hasashe.

## Tushen shaida

```text
✓ QUANTITATIVE → analytics, funnels, retention, A/B tests (what is happening)
✓ QUALITATIVE → user interviews, support tickets, session recordings (why)
→ combine both: numbers tell you WHAT, conversations tell you WHY
```

Kwantitatibi babu kwalitatif yana gaya maka funnel yana faɗi a mataki 3 amma ba *me* — kuma ba za ka iya gyara me da ba ka fahimta ba.

## Gwaje-gwaje (A/B gwaje)

```text
✓ Form a HYPOTHESIS → "shorter signup → higher completion"
✓ Define the SUCCESS METRIC up front (and guardrails)
✓ Run on a meaningful, RANDOMIZED sample to significance
✓ Decide BEFORE looking → avoid cherry-picking results
✓ Beware false positives, tiny samples, and short-term wins that hurt long-term
```
