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 are the units of measurement for the standard error of mean?
The same units as the mean itself. If the units of the mean, are, for example miles; then the error units are miles.
What affects the standard error of the mean?
The standard error of the underlying distribution, the method of selecting the sample from which the mean is derived, the size of the sample.
What happens to the standard error of the mean if the sample size is decreased?
The standard error increases.
What does source of error mean?
A source of error is something that could have caused you to obtain an incorrect result.
Why is zero error not considered in spherometer?
No, you have not any knowledge about spherometer. In spherometer also, similar to other measuring instruments zero error should be considered every time; in order to achieve accurate value.
How is backlash error avoided?
Yes
Why spherometer is called spherometer?
The reason a spherometer is called a spherometer is because it measures the radius of a sphere.
Why spherometer is so called?

What is the source of error in a bourdon gauge?
· Friction· Wear· And backlash in gears.
What is spherometer uses?

What is the unit of measurement in spherometer?
A spherometer is an instrument for the precise measurement of the radius of a sphere. The spherometer directly measures a sagittal. Since the spherometer is essentially a type of micrometer, it measures very small things like millimeters.
What is the Difference between screw gauge and spherometer?
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
