Well for one thing, you can use it to find the average and the standard deviation. Suppose we throw the dice N times and then average all of the results together. We expect that each of the six faces will show up 1/6 of the time, or N/6 total times if we throw N times.

Standard deviation - Simple English Wikipedia, the free encyclopedia
Standard Deviation Is Like An Average Of The Deviation: When we calculate the standard deviation, it is a way to get “an average deviation”. In this way, we then have a “typical” number we can use in discussions about the spread of the data. In our first step when calculating the standard deviation, we take our mean (typical value of ...

Standard deviation is a statistical calculation that is a measure of how much scatter (or uncertainty) there is in the data. If you round the standard deviation to one significant digit, that will tell you in which decimal place the uncertain digit of your final result lies. For example, ten quarters were weighed, and the average weight was ...

Think of the standard deviation as roughly an average distance of the observations from their mean. If all of the observations are the same, then the standard deviation will be 0 (i.e. no spread). Otherwise the standard deviation is positive and the more spread out the observations are about their mean, the larger the value of the standard ...

A random sample of 12 female students yielded a mean of 0.45 and standard deviation of 1.5. 99% CI to estimate the true mean weight change is (-0.8949 , 1.7949). Would you believe me if I claimed the average weight change was 0? How would you answer this using the hypothesis testing? Specify the hypothesis. Show test statistics= 1.04

For a population, the standard deviation can be estimated by a modified standard deviation (s) of a sample. The formulas are given below. Given a random variable (in blue), the standard deviation σ is a measure of the spread of the values of the random variable away from its mean μ.

Given that an average of 18 people can fit inside a square measuring 5 feet by 5 feet, estimate the size of a crowd that is 10 feet deep on both sides of the street standing along a 1-mile section of a parade route. (1 mile = 5,280 ft) The size of a television is the length of the diagonal of its screen in inches.

The standard deviation, when first presented, can seem unclear. By graphing your data, you can get a better "feel" for the deviations and the standard deviation. In symmetrical distributions, the standard deviation can be very helpful but in skewed distributions, the standard deviation may not be much help.

The standard deviation is . σ = 12 mm. As a class project, each student in a class of 200 students sample 100 random people and find the sample average of the blood pressures of his or her 100 people. If the class draws a histogram of the resulting 200 averages, about what would you expect the average standard deviation of the histogram to be?
