What causes systematic error?
Improper calibration of the measuring instrument. If the measuring instrument is not at zero prior to measuring the object you will get a systematic error which, is a value either always higher or always lower then the actual value of the object.
Parallax error how it can be avoided?
I'm assuming you're measuring somethings' displacement along a scale. There are three simple ways of reducing parallax error in that case: 1: Attach a straight object (like a ruler or straightened paperclip) to the thing you're measuring the displacement of, it should stick out of the object perpendicularly to the scale you're measuring the displacement on. 2: Make sure that object is as close to your scale as possible, but not touching. 3: Put your eyes level with the object, and as close to it as you safely can.
Why is necessary to use measuring tools in measuring length of an object?
It is necessary because measuring tools help you measure the length of an object accurately.
What is the equivalent ratio of 156 390?
[object Object]
What is the most useful descriptive statistic of measuring dispersion?
The standard error.

What are the errors committed in measuring accuracy of an object?
Common errors in measuring accuracy of an object include human error, instrumental error, environmental factors, and systematic errors from calibration issues. Additionally, inconsistent measurement techniques and insufficient sample size can also lead to inaccuracies in measuring accuracy.

What is parallax error in measurement?
:parallax error occurs when the line of sight or measure is not at right angles ( perpendicular ) to the objects being measured. Any distance between the object and the measuring reference ( for example a rule ) will cause a misreading. This error will increase as the distance between the object and the reference increases.
Why is necessary to use measuring tools in measuring length of an object?
It is necessary because measuring tools help you measure the length of an object accurately.
What are the Causes of phase angle error and ratio error at Current Transformers?
RATIO ERROR The secondary current is less than the expected value. The secondary is less in magnitude. This diffence is known as ratio error. PHASE ERROR The angle between the expected and actual secondary current is known as phase error.
If someone is using a balance during a laboratory experiment what are they measuring?
Measuring how heavy an object is compared to another object.
Why is use of zero error necessary in a measuring instrument?
Zero error is necessary for measuring instruments for measuring accurate results because it helps to check that the instrument which we are using is whether correct or wrong
Is measuring software used to write letters?
[object Object]
What meant by the tolerance of a measuring instrumental?
Intrinsic error.
What are some of the challenges of measuring accurately?
Some challenges of measuring accurately include human error, instrument calibration issues, environmental factors affecting measurements, and variations in the object being measured. It is important to account for these challenges to ensure the precision and reliability of measurements.
How do you get the the volume of shapes?
by measuring the object
