refers to difference between sample & population that exist only coz of the observations that happened to be selected for the sample.

Types of systematic errors with examples?

There are three types of systematic error....they are as follow (1) instrumental uncertainties that are attributable to imperfections in measuring devices, (2) method uncertainties that are caused by nonideal chemical or physical behavior of analytical systems. (3) personal uncertainties that result from physical or psychological limitations of the analyst

What factor can researcher control that will reduce the risk of a type 1 error?

In statistical tests there are 2 main types of Errors, Type I and Type II. Type 1 errors occur when you reject a null hypothesis that is actually true and is thus refereed to as a false positive. Type II errors are essentially the opposite, accepting a null hypothesis that is false, and is often called a false negative. You can reduce the risk of a type I error by lowering the value of P that you're significance test must return to reject the null, but doing so will increase the chance of a type II error. The only way to reduce both is to increase the entire sample size. Alternatively, in some cases, it may also be possible to lower the standard deviation of the experiment, which would also decrease the risk of type I and type II errors.

What are the two types of errors?

The two types of errors are systematic errors and random errors. Systematic errors are consistent, repeatable errors that occur due to flaws in measurement instruments or methods, often leading to bias in results. Random errors, on the other hand, arise from unpredictable fluctuations in measurements, resulting in variations that can affect the precision but not the accuracy of the results. Both types of errors can impact the reliability of data and findings in research and experiments.

What two types programming errors that can occur?

Two common types of programming errors are syntax errors and logic errors. Syntax errors occur when the code violates the rules of the programming language, preventing it from compiling or running. Logic errors, on the other hand, arise when the code runs without crashing but produces incorrect or unintended results due to flawed logic or assumptions in the algorithm. Both types can significantly impact the functionality and reliability of a program.


What are two types of errors in physics?

Two types of errors in physics are systematic errors, which result in measurements consistently being either higher or lower than the true value, and random errors, which occur randomly and can affect the precision of measurements. Systematic errors are usually due to equipment limitations or procedural mistakes, while random errors are caused by unpredictable variations in measurements.
