Introduction Measurement is a crucial part of statistics and science. But no measurement is ever 100% accurate! 📏 Whether you're measuring height, weight, distance, or temperature , there’s always some error involved. In this blog, we’ll explore the different types of measurement errors , how to calculate them, and ways to minimize them. Types of Measurement Errors 1️⃣ Absolute Error – The Basic Difference Absolute error is the difference between the actual (true) value and the measured value . It shows how much our measurement deviates from reality. 📌 Formula: Absolute Error = |Measured Value - True Value| 📌 Example: If the actual temperature is 38°C , but a thermometer reads 38.5°C , the absolute error = 0.5°C . 2️⃣ Relative Error – Comparing Errors Relative error helps us compare errors across different measurements by expressing the absolute error as a fraction of the actual value. 📌 Formula: Relative Error = Absolute Error / True Value 📌 Example: ...
In today’s data-driven world, statistics is a superpower. From making predictions to uncovering hidden patterns, statistical skills can shape industries, drive decisions, and even change lives.
