No. It's the number that will help you work out the percentage.
The standard deviation in a standard normal distribution is 1.
The standard deviation in a standard normal distribution is 1.
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.

No. It's the number that will help you work out the percentage.
One standard deviation for one side will be 34% of data. So within 1 std. dev. to both sides will be 68% (approximately) .the data falls outside 1 standard deviation of the mean will be 1.00 - 0.68 = 0.32 (32 %)

The standard deviation in a standard normal distribution is 1.
4.55% falls outside the mean at 2 standard deviation
Standard deviation doesn't have to be between 0 and 1.
The standard deviation in a standard normal distribution is 1.
Mean 0, standard deviation 1.
Mean = 0 Standard Deviation = 1
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.
16.5 is 1 standard deviation from the mean. If you add the mean of 14 to the 1 standard deviation of 2.5, the result is 16.5.
