କ'ଣ Z-Score Calculator?

▾

A z-score (standard score) expresses a value's distance from the population mean in standard deviation units. z = (x − μ) / σ. Positive z = above average; negative z = below average.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

କିପରି Z-Score Calculator

▾
  1. 1z = (x − μ) / σ
  2. 2Percentile from z-score: use standard normal CDF
  3. 3z=1.96 → 97.5th percentile
  4. 4Enables comparison across different measurement scales

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

▾
ଉଦାହରଣ 1
ଦିଆ ଯାଇଛି:Score 85 · Mean 70 · SD 15
ଫଳ:z = 1.0 → 84th percentile

(85-70)/15=1.0; P(Z<1)=84.1%
