Weighted Standard Deviation – Giving Data Its True Weight! ⚖️
Not all groups in HR data are equal. Some teams are huge, others are small — and treating them the same can distort results. That’s where Weighted Standard Deviation (WSD) steps in.
✨ What it does:
WSD measures how spread out data is, but with a twist — it gives bigger groups more influence.
👉 HR Example:
* Dept A (500 employees) → Engagement 80%
* Dept B (50 employees) → Engagement 70%
* Dept C (100 employees) → Engagement 60%
Instead of letting Dept B skew results, WSD ensures Dept A’s larger size has the right impact.
💡 For HR leaders, this means smarter insights on engagement, performance, and pay fairness — without small groups distorting the story.
