What is the relevance of calculating standard deviation?
The Standard Deviation will give you an idea of how 'spread apart' the data is. Suppose the average gasoline prices in your town are 2.75 per gallon. A low standard deviation means many of the gas stations will have prices close to that price, while a high standard deviation means you would find prices much higher and also much lower than that average price.
Why is the standard deviation of a distribution of means smaller than the standard deviation of the population from which it was derived?
The reason the standard deviation of a distribution of means is smaller than the standard deviation of the population from which it was derived is actually quite logical. Keep in mind that standard deviation is the square root of variance. Variance is quite simply an expression of the variation among values in the population. Each of the means within the distribution of means is comprised of a sample of values taken randomly from the population. While it is possible for a random sample of multiple values to have come from one extreme or the other of the population distribution, it is unlikely. Generally, each sample will consist of some values on the lower end of the distribution, some from the higher end, and most from near the middle. In most cases, the values (both extremes and middle values) within each sample will balance out and average out to somewhere toward the middle of the population distribution. So the mean of each sample is likely to be close to the mean of the population and unlikely to be extreme in either direction. Because the majority of the means in a distribution of means will fall closer to the population mean than many of the individual values in the population, there is less variation among the distribution of means than among individual values in the population from which it was derived. Because there is less variation, the variance is lower, and thus, the square root of the variance - the standard deviation of the distribution of means - is less than the standard deviation of the population from which it was derived.
Inequalities to show the upper and lower regions of a decimal gcse level?
To shade the upper region of a line means the inequality has a greater than value while shading the lower region means the inequality has a less than value.
What does estimate in hundreds mean?
It means to round up if the number is bigger than 5 and if the number is lower than 5 you round down
Is 36.05 lower than 36.055?
Yes, 36.05 is lower than 36.055 is.
What is the standard performance for 3g?
The standard performance for 3g depends on what kind of service you are using. For cell phones it provides internet speeds of between 1 and 14 Mbps. For data services it allows for no lower than 200 k/bits per second.
Will the standard error always be lower than the standard deviation?
No.

Why is the standard toilet seat always lower in height than the standard dining room seat?
Because the lower height creates a better angle to facilitate defecation in a clean manner.
