00
Q2596
what is captcha code
CAPTCHA
Although most CAPTCHAs are letter pictures randomly generated, many of them have become difficult even for a human to read , so picture CAPTCHAs were created in which a human is shown a simple test to show a picture of a certain animal (given few animal pictures), which is simple for a human being to process, and therefore easy to pick, while a bot cannot process and solve the question because although it can analyze the picture, it cannot easily guess the animal.

00
Q2602
what is standard deviation in statistics
Standard deviation
Cumulative probability of a normal distribution with expected value 0 and standard deviation 1.
00
Q2602
what is standard deviation in statistics
Standard deviation
In statistics and probability theory , standard deviation (represented by the symbol sigma, σ ) shows how much variation or dispersion exists from the average ( mean ), or expected value.
00
Q2602
what is standard deviation in statistics
Standard deviation
A low standard deviation indicates that the data points tend to be very close to the mean ; high standard deviation indicates that the data points are spread out over a large range of values.
00
Q2602
what is standard deviation in statistics
Standard deviation
The standard deviation of a random variable , statistical population , data set, or probability distribution is the square root of its variance .
00
Q2602
what is standard deviation in statistics
Standard deviation
It is algebraically simpler though practically less robust than the average absolute deviation .
00
Q2602
what is standard deviation in statistics
Standard deviation
A useful property of standard deviation is that, unlike variance, it is expressed in the same units as the data.
00
Q2602
what is standard deviation in statistics
Standard deviation
Note, however, that for measurements with percentage as unit, the standard deviation will have percentage points as unit.
00
Q2602
what is standard deviation in statistics
Standard deviation
In addition to expressing the variability of a population, standard deviation is commonly used to measure confidence in statistical conclusions.
00
Q2602
what is standard deviation in statistics
Standard deviation
For example, the margin of error in polling data is determined by calculating the expected standard deviation in the results if the same poll were to be conducted multiple times.
00
Q2602
what is standard deviation in statistics
Standard deviation
The reported margin of error is typically about twice the standard deviation ­– the radius of a 95 percent confidence interval .
00
Q2602
what is standard deviation in statistics
Standard deviation
In science, researchers commonly report the standard deviation of experimental data, and only effects that fall far outside the range of standard deviation are considered statistically significant – normal random error or variation in the measurements is in this way distinguished from causal variation.
00
Q2602
what is standard deviation in statistics
