Z-Score
Standardize your data by finding the distance in standard deviations.
Z-Score (Standard Score)1.0000
Base Formula
Z = (X - μ) / σ
Resolution
X = 85
Média (μ) = 75
Desvio Padrão (σ) = 10
Z = (85 - 75) / 10 = 1.0000
The Universal Language of Data
How do you compare who did better: a student who scored 8 on a math test worth 10, or someone who scored 70 on a history test worth 100? With the Z-Score, you eliminate the 'weight' of different scales and discover with scientific accuracy who achieved the best real performance within their own class.
