When a tornado forms or passes over a water surface‚ it is called a waterspout. Like tornadoes‚ they form in many shapes and often occur in series or families. Measurements of tornadoes can be a few kilometers an hour to as high as 64 to 80 kilometers per hour. We should know what to do before‚ during‚ and after a tornado has hit our town. Tornados cause much damage and we people should be prepared before a tornado‚ during a tornado and what to do after a tornado. Before a tornado‚ we should listen

Introduction to Measurements & Error Analysis The Uncertainty of Measurements Some numerical statements are exact: Mary has 3 brothers‚ and 2 + 2 = 4. However‚ all measurements have some degree of uncertainty that may come from a variety of sources. The process of evaluating this uncertainty associated with a measurement result is often called uncertainty analysis or error analysis. The complete statement of a measured value should include an estimate of the level of confidence associated

upon obtaining measurements. No measure is ever exact due to errors in instrumentation and measuring skills. If you were to obtain the mass of an object with a digital balance‚ the reading gives you a measure with a specific set of values. We can assume that the actual measure lies either slightly above or slightly below that reading. The range is the uncertainly of the measurement taken. More accurate instruments have a smaller range of uncertainty. Whenever you take a measurement‚ the last recorded

Fawzi Abdelgani Ahmad . Experiment 1: Experimental Uncertainty (Error) and Data Analysis Jan/30/2013 PRELAB: 1. Do experimental measurements give the rule value of a physical quantity? Explain. No. Statistical methods are used to establish the deviations in the measurement. 2. Distinguish between random (statistical) error and systematic error‚ and give an example of each. Random errors are caused by unknown and unpredictable changes in the experiment like mechanical

Measurements and Error Analysis‚ #1‚ Chris Baca Discussion of differences The purpose of this experiment is to understand why we have variances in measurements and how to reduce the variances. When taking a measurement there are multiple factors that affect its value. The more the measurement is taken the measurements average is closer to the actual value. Other factors include the instruments calibration‚ cleanliness of the inside of the measuring arms and human error in reading the measurements

measuring and interpreting individual differences. Rigorous measurement is a prerequisite in selection‚ because our ability to distinguish from one person to another is determined by the precision with which we can measure the variables. In this context various types of scales of measurement are used. Scales of measurement is simply a means by which individuals can be distinguished from one another. Four types of scales of measurement exist: 1. Nominal 2. Ordinal 3. Interval and 4.Ratio. Nominal

THEORY: Statistical variation and measurement uncertainty are unavoidable. A theory is consistent if the measurement is 2m +/- 1m. Uncertainty rises from statistical variation‚ measurement precision‚ or systematic error. EXPERIMENTAL OVERVIEW: Part 1. Coin Toss: Statistical Variation: Sixteen coins were tossed nine times and the number of heads was counted to determine variation associated with random events. Part 2. Measurement Precision: The measurements (length‚ width‚ and height) of the
