By how controlable (reproduceable/predictable) that variable is.
9f you are using the equation %error =[(oberved value - true value)/true value]x100 a negative percent indicates the observed value is less than the true value by the calculated percent.
error
In statistical significance testing, the p-value is the probability of obtaining a test statistic result at least as extreme or as close to the one that was actually observed. This is assuming that the null hypothesis is true.
Accuracy
This is the accuracy of a value.
The probability of the observed value or something more extreme under the assumption that the null hypothesis is true.
Accuracy
Accuracy
An absolute personal equation is the difference between an observed value and a standard value assumed as being true.
No. accuracy is a measure of how close the measurements are to the true value.
The probability of the observed value or something more extreme under the assumption that the null hypothesis is true. That is, the probability of standard scores at least as extreme as the observed test statistic.
How close a value is to the true value.
