i.e. different measurements for samples. Our sources of error could have included eye measurement error‚ timing of set solutions error‚ measurement errors‚ and small calculation errors. Among other variables‚ the calibration of the analytical balance and spectrophotometer could have been off slightly‚ yet our results‚ like most other groups‚ still followed the general trend line generated by the graph using Beer’s Law. The measurement errors could have occurred due to the fact that one partner’s perspective

when completing a task and that often leads me to over think small errors I may make. I perceive these small errors as greater flaws in my mind‚ and will not declare a task complete until it is perfect. I have learned to use this to my advantage by never making the same mistake twice through my critical thinking process. 2. When I make mistakes I tend to over-think my error. My potentially small error turns into a bigger error mentally than it actually is‚ which causes me to think about the problem

The high accidental rates might be lead by the human errors‚ which are including the person approach and the system approach(Reason‚ 2000). However‚ there are some causation models‚ such as James Reason’s model‚ which known as the Swiss Cheese Model‚ provides ascent to quite distinct philosophies of error management(Reason‚ 2000). Besides‚ there are some assets are found by the comparison among the Reason model and other models

information is lacking since there are no formal procedures installed that monitor his actions. Further‚ the management of the firm has never received any training in giving constructive feedback and in avoiding common errors‚ such as the error of central tendency or the contrast error.
