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.
What is the most useful descriptive statistic of measuring dispersion?
The standard error.
What combination of factors produces the smallest risk of a type 1 error?
A combination of factors increase the risk of a Type 1 error. Giving the wrong amount or wrong diagnosis for a wrong drug would certainly increase an error.
Why is the use of zero error is necessary in in a measuring instruments?
haahahahh
What is meant by non sampling error?
A systematic error. This may arise because the measuring instrument is not properly calibrated or because there is a bias in recording the results.
What is 0.019 to 1sf?
It is 0.02
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
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.
What meant by the tolerance of a measuring instrumental?
Intrinsic error.
What is the lower bound to 1sf of 60000?
55000
What is the most useful descriptive statistic of measuring dispersion?
The standard error.
What are the sources of error in measuring heart rate by palpation?
stop watch
How do you avoid systematic error?
A systematic error is a reproducible inaccuracy with a nonzero mean. It can be avoided by ensuring that the measuring equipment is not flawed.
What type and source of error when or while using vernier caliper?
The Vernier caliper is an extremely precise measuring instrument Error is almost impossible The error that we must always look out for is the zero error and parralex error.
What is zero error in vernier caliper?
The zero error of a measuring instrument is the measure that it shows when it should actually be showing zero.
What combination of factors produces the smallest risk of a type 1 error?
A combination of factors increase the risk of a Type 1 error. Giving the wrong amount or wrong diagnosis for a wrong drug would certainly increase an error.
What is the greatest possible error when measuring to the nearest quarter of an inch in fraction?
An eighth of an inch.
