Explanation:By using the sunglasses while looking at If your sunglasses are polarized, instead of only seeing the surface of a lake or river, you will suddenly be able to see through the glare and into the water below.
Another one is by comparing two sunglasses, hold your glasses and another one simultaneously and look through both pairs at the same time. Then, rotate one pair of sunglasses about 60 degrees. If both pairs of glasses are polarized, the overlapping area will darken as they filter out excess light. If your pair isn't polarized, however, you won't notice any difference.
Also it can be determined by simple computer test If you rotate your glasses sideways while looking at a computer monitor through polarized glasses, portions of your screen will become blank or go dark. The same also applicable to LCD display screens such as the ones on a gas pump.

Answer:
The standard deviation is a measure of the dispersion of a series of data
Result = x_{average} ± σ
Explanation:
The standard deviation is a measure of the dispersion of a series of data, it is generally used when a series of measurements of some parameters are made and it is desired to take into account the statistical fluctuations of these measurements, its formula is
where N is the number of measurements
This is a measure equivalent to the absolute error in a single measurement.
Therefore, the number of decimal places in a result must not be greater than the standard deviation.
Result = x_{average} ± σ
