Understanding Z-Score
Z-Score: The Z-score, also known as the standard score, measures how many standard deviations a data point is from the mean of a dataset.
Formula: \( Z = \frac{X - \mu}{\sigma} \), where:
- X = Data value
- μ = Mean of the dataset
- σ = Standard deviation of the dataset
Example: If a test score is 85, with a mean of 70 and a standard deviation of 10, the Z-score is:
Z = (85 - 70) / 10 = 1.5
This means the test score is **1.5 standard deviations above the mean**.
Age Calculator
Age calculators help determine the exact age by inputting birth date details. These are widely used in legal, educational, and medical fields.
Simply enter your birthdate, and our system will provide your precise age in years, months, and days. This tool is perfect for tracking age-related milestones.
