Understanding Uncertainty in Measurements
Learn about uncertainty and measurements, including percent uncertainty calculations.
00:00:01 This video explains the concept of uncertainty in measurements and how to determine the uncertainty for a particular device.
📏 Every measurement has some uncertainty.
🔍 To determine uncertainty, divide the smallest division by 10.
🔢 The uncertainty determines the number of decimal places in the measurement.
00:01:05 Understanding Uncertainty & Measurements: Learn how measurements can have a range of values due to uncertainty, affecting the precision of the result.
📏 Uncertainty in measurements is an important factor to consider.
🔢 Measurement uncertainties can be expressed as a range of values.
⚖️ The uncertain digit in a measurement determines the level of uncertainty.
00:02:11 Learn about uncertainty and measurements, including percent uncertainty calculations, in this concise video summary.
📏 One way to calculate uncertainty is by determining the range of measurements, such as from 25.99mm to 26.01mm.
📊 Percent uncertainty can be calculated by dividing the uncertainty by the measured value, multiplied by 100.
🔢 For example, a measurement of 2.54cm with an uncertainty of 0.01cm would have a percent uncertainty of 0.4%.
