What do standard deviation error bars indicate when they go past your minimum value?

∙ 8y ago
If the minimum value is the minimum observed value then it indicates that the distribution goes below the minimum observed value.
If the minimum value is the minimum defined for the distribution then it indicates that
- the data do not come from the proposed distribution,
- estimates for the mean or standard deviation are incorrect, or
- you have got a sample which is atypical.

What do error bars show within treatments?
Error bars within treatments typically show the variability or uncertainty in the data points related to that specific treatment. They can represent standard deviation, standard error, confidence intervals, or other measures of dispersion, depending on the study design and statistical analysis. Error bars provide a visual way to assess the precision and reliability of the data within each treatment group.
Scientific word for mistake?
The scientific word for mistake is "error." It refers to a deviation from the expected or correct outcome in a process, experiment, or calculation.
Will display to indicate a cell contains an error or message?
Common ways to indicate that a cell contains an error or message in Excel are through error indicators (green triangle in the top left corner of the cell), error messages, or custom formatting (e.g., changing the cell color or font style). You can also use conditional formatting to highlight cells with errors or messages.
Vitamins to analyze the variation of vitamin supplement tablets you randomly select and weigh 14 tablets the results in milligrams are shown use 90 percent level of confidence?
To analyze the variation of vitamin supplement tablets, calculate the mean and standard deviation of the weights of the 14 tablets. With a 90% confidence level, determine the margin of error using the t-distribution. This margin of error will help define the range within which the true mean weight of the tablets is likely to lie.
How is sph measured?
Sph (sphere) is a measurement of refractive error in eyeglass prescriptions, indicating the amount of nearsightedness or farsightedness. It is measured in diopters. Positive sph values indicate farsightedness, while negative values indicate nearsightedness.
Why is standard deviation of a statistic called standard error?
The standard error is the standard deviation divided by the square root of the sample size.
What is the difference between standard error of mean and standard deviation of means?
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
Why is the standard error a smaller numerical value compared to the standard deviation?
Let sigma = standard deviation. Standard error (of the sample mean) = sigma / square root of (n), where n is the sample size. Since you are dividing the standard deviation by a positive number greater than 1, the standard error is always smaller than the standard deviation.
Will the standard error always be lower than the standard deviation?
No.
Can standard deviation equal standard error?
If n = 1.
The standard deviation of a point estimator is called the?
standard error
What if the standard deviation is negative?
There is a calculation error.
Is standard deviation same as standard error?
From what ive gathered standard error is how relative to the population some data is, such as how relative an answer is to men or to women. The lower the standard error the more meaningful to the population the data is. Standard deviation is how different sets of data vary between each other, sort of like the mean. * * * * * Not true! Standard deviation is a property of the whole population or distribution. Standard error applies to a sample taken from the population and is an estimate for the standard deviation.
Is standard deviation and standard error the same?

Difference between standard error and sampling error?
Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
What is the standard error of the sampling distribution equal to when you do not know the population standard deviation?
You calculate the standard error using the data.
How does one calculate the standard error of the sample mean?
Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.
