The Behaviorally Anchored Rating Scale (BARS) is a performance appraisal method that combines elements of both graphic rating scales and critical incident methods. It evaluates employee performance by using specific behavior examples as anchors to rate performance levels, providing specific and observable criteria for assessing performance. This method helps reduce rating errors and provides a more objective assessment compared to traditional rating scales.
The F scale was developed by Dr. T. Theodore Fujita in 1971. The highest rating on the scale is F5, which indicates tornadoes with winds speeds of over 200 mph.
The highest rating on the Mercalli scale is XII, which indicates total destruction and extreme devastation with waves noticeable on the ground.
The rating system that estimates the total energy released by an earthquake is called the moment magnitude scale (Mw).
The Fujita (F) scale was originally developed by Dr. Tetsuya Fujita at the University of Chicago. The current scale, the Enhanced Fujita (EF) scale was developed by a large group of engineers and scientists working at Texas Tech University.
Yes, there is a rating system for thunderstorms called the Enhanced Fujita Scale (EF-Scale) which rates the intensity of tornadoes spawned by thunderstorms. The scale ranges from EF0 (weakest) to EF5 (strongest). Additionally, the Storm Prediction Center issues severe storm watches and warnings based on the potential for severe thunderstorms to occur.
