Should I use standard deviation or standard error?

So, if we want to say how widely scattered some measurements are, we use the standard deviation. If we want to indicate the uncertainty around the estimate of the mean measurement, we quote the standard error of the mean. The standard error is most useful as a means of calculating a confidence interval.

What is uncertainty and why does it matter?

Why does uncertainty matter? Uncertainty affects all measurements. For critical measurements uncertainty can mean the difference between a pass or fail decision.Esfand 20, 1398 AP

How do you interpret a standard deviation?

More precisely, it is a measure of the average distance between the values of the data in the set and the mean. A low standard deviation indicates that the data points tend to be very close to the mean; a high standard deviation indicates that the data points are spread out over a large range of values.

Is it better to have a higher or lower standard deviation?

Standard deviation is a mathematical tool to help us assess how far the values are spread above and below the mean. A high standard deviation shows that the data is widely spread (less reliable) and a low standard deviation shows that the data are clustered closely around the mean (more reliable).
