An experimental error is is
A theoretical error is an error that is not quite proven, which means that it is also arguably not an error.
Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
In stats, a sampling error is simply one that comes from looking at a sample of the population in question and not the entire population. That is where the name comes from. But there are other kinds of stats errors. In contrast, non sampling error refers to ANY other kind of error that does NOT come from looking at the sample instead of the population. One example you may want to know about of a non sampling error is a systematic error. OR Sampling Error: There may be inaccuracy in the information collected during the sample survey, this inaccuracy may be termed as Sampling error. Sampling error = Frame error + Chance error + Response error.
In statistics, there are two types of errors for hypothesis tests: Type 1 error and Type 2 error. Type 1 error is when the null hypothesis is rejected, but actually true. It is often called alpha. An example of Type 1 error would be a "false positive" for a disease. Type 2 error is when the null hypothesis is not rejected, but actually false. It is often called beta. An example of Type 2 error would be a "false negative" for a disease. Type 1 error and Type 2 error have an inverse relationship. The larger the Type 1 error is, the smaller the Type 2 error is. The smaller the Type 2 error is, the larger the Type 2 error is. Type 1 error and Type 2 error both can be reduced if the sample size is increased.

POST will indicate error messages by a series of beeps or a series of lighted-up LEDs (depending on your computer).
It issues a number of short beeps.
It places an error message in the BIOS.
You would use a caret (^) inserted above or below the error to indicate it needs to be corrected.
During the POST a single beep indicate normal operation of the PC. hope this will help cathrine mauchi
A typographical error for "post meridiem" meaning afternoon.

POST means "Power On Self Test", and is a series of tests the computer will conduct before loading your operating system (i.e. Windows). Most desktop computers that pass POST will sound a single short beep. If POST fails with a "no video" error, that probably means the computer was unable to properly initialize the video device during POST. You will likely need your computer serviced, in this event.
