Document Summary
Mean ( : also known as average, where xi = individual values of x making up the set of n replicate measurements. Median: middle result of replicate data when arranged in ascending or descending order if data set has even number of replicates, the median can be evaluated as the mean of the middle pair. 1: the number of significant figures is equal to the number of digits needed to represent a value in scientific notation without the loss of accuracy. The significance of zeroes: only significant when they appear in the middle of a number or at the end of a number on the right side of the decimal point. Absolute and relative uncertainty: absolute uncertainty expresses the margin of uncertainty associated with a measurement (ex. Slow or incompetent reactions, istability of reactants and products, side product formation etc: personal error carelessness, inattention, being under the influence etc.
