- What is implied by standard deviation being much larger than the mean?
What does it imply for standard deviation being more than twice the mean? Our data is timing data from event durations and so strictly positive (Sometimes very small negatives show up due to clock
- probability - Why are mean 0 and standard deviation 1 distributions . . .
The mean of 0 and standard deviation of 1 usually applies to the standard normal distribution, often called the bell curve The most likely value is the mean and it falls off as you get farther away
- How does the sampling distribution of sample means approximate the . . .
The mean of the sample means will approximate the population mean Now what I don't understand is a lot of the times you see "A sample of 100 people…" Wouldn't we need 10s or 100s of samples of 100 people to approximate the population of the mean?
- Which mean to use and when? - Cross Validated
So we have arithmetic mean (AM), geometric mean (GM) and harmonic mean (HM) Their mathematical formulation is also well known along with their associated stereotypical examples (e g , Harmonic mea
- What is the difference between mean value and average?
The mean you described (the arithmetic mean) is what people typically mean when they say mean and, yes, that is the same as average The only ambiguity that can occur is when someone is using a different type of mean, such as the geometric mean or the harmonic mean, but I think it is implicit from your question that you were talking about the arithmetic mean
- mean - How do I calculate confidence intervals for a non-normal . . .
It demonstrates the Central Limit Theorem, i e how the sampling distribution of the mean tends to the normal, even for values following a very "unnormal" distribution
- Interpretation of mean in this example - Cross Validated
N = 259 Mean = 72 StdDev = 7 I don't remember anything about this, and my career doesn't deal with any of this I want to know how can I interpret these results with those values What does it mean that the mean was 72? What does it mean that the standard deviation value is 7? What does it mean if, for example, I obtained an 88 or a 78 on the test?
- Mean absolute deviation vs. standard deviation - Cross Validated
After calculating the "sum of absolute deviations" or the "square root of the sum of squared deviations", you average them to get the "mean deviation" and the "standard deviation" respectively The mean deviation is rarely used
