An error (from the Latin error, meaning "wandering") is an action which is inaccurate or incorrect. In some usages, an error is synonymous with a mistake.
In statistics, "error" refers to the difference between the value which has been computed and the correct value. An error could result in failure or in a deviation from the intended performance or behavior.
I know that least count is the smallest measurement that is possible with a measuring device. But I fail to understand the exact meaning of least count error. According to my textbook, the following is the definition of least count error.
"Least count error is the error associated with the...
Question is simple: what happens when ##DNL = -1 LSB## where DNL signifies differential nonlinearity and LSB stands for Least Significant Bit. It is also required to try and sketch such condition.
Equation for differential nonlinearity: $$DNL(i) =...
I have a question that maybe has to do more with Mathematics, but if you do experimental physics you find it quite often.
Let's assume that we want to measure two quantities x and y that we know that they relate to each other linearly. So we have a set of data points xi and yi...
Please bear with me...
In a curriculum in mechanical engineering, there is a set of standard topics: statics, dynamics, vibrations, fluid mechanics, thermondynamics, etc.
What is Artificial Intelligence, and what does it entail?
(at the moment, it seems like a buzz phrase that does not...
What is the uncertainty in 5.00mm measured by an analog device?
No equations, Uncertainty and error analysis question
The Attempt at a Solution
I know that the uncertainty is half the smallest division but i can't figure out what is the uncertainty and...
I was reading an 1803 paper by Thomas Young (of double slit fame), "Experiments and Calculations relative to physical Optics". In it, he lists various dimensions of fringes of light and things.
All without any error bars.
It got me thinking, what's the history of error bars in scientific...
I have doubt in calculating the permissible error. It goes as follows
Measure of two quantities along with the precision of respective measuring instrument is
A = 25.0 ± 0.5 m/s, B = 0.10 ± 0.01 s. A physical quantity C is calculated as C = A × B. What will be the value of...
Imagine we are sampling of a gaussian signal along time and need to know the power/variance associated with the first N spectral components. So we take our favorite fft algorithm to get the PSD.
The error associated with a given estimated spectral component f(w) (w is the...
Hi! I am currently trying to write a code in C to simulate the orbit of planets around the Sun in the solar system.
I am using the velocity Verlet approach and finding that my code produces no acceleration in the ##y##-direction (aside from for ##t_n = 0##,) and that the planet just flies off...
Hey guys, I'm pretty new and desperate. I been trying to compile this program for a while and keep jumping from error to error.
Currently I have the following error:
Error: Rank mismatch in argument 't' at (1) (scalar and rank-1)
I have checked that my arrays are correctly. I have checked that...
For my coursework task, i am to quantify and discuss errors associated with an experimental procedure.
This involved a thyristor control unit which allowed the firing angle of two thyristors (in a half controlled bridge rectifier) to be varied with a rotary dial or pot/rheo...
