Question

what is error? types of error?

Answer 1

The error and its types are explained below:

Error

• A result achieved that differs from the intended outcome, real value, or reference value is referred to as an error.

Different types of errors are described below:

1. Errors with a pattern or Systematic errors

• The measured value is skewed owing to a specific reason for this sort of mistake.
• Measurement variances occur due to changes in equipment or certain external conditions.

2. Errors of probability or Random errors

• Random conditions during the measuring procedure produce this form of mistake.

3. Inadvertent error or Negligent errors

• This sort of inaccuracy is produced by measuring an individual's lack of experience or inappropriate processes.

Answer 2

Answer:

Concept:

An error is an inaccurate or improper action (from the Latin error, meaning "wandering"). An error and a mistake are sometimes used interchangeably. The term "error" in statistics describes the discrepancy between the computed result and the correct value. Failure or a deviance from the anticipated performance or behaviour could come from an error.

Answer:

Error:

A divergence from precision or correctness is known as a "error." A "mistake" is an error brought on by a fault, such as poor judgement, negligence, or forgetfulness. Now, if the cops stop me after I run a stop sign because I was distracted and in a hurry, that is a mistake. However, it would be a mistake if I attempted to park in a spot where there were conflicting signs and received a penalty because I misread the signs' intended meaning. It would be incorrect the first time. It would be a mistake the second time because I should have gained a lot of knowledge. According to the source they originate from, errors can be divided into three categories.

These categories are:

1. Gross Errors
2. Random Errors
3. Systematic Errors

1. Gross Errors:

In essence, this category accounts for human error and other faults made while reading, recording, and listening. This group of measuring errors includes the most frequent ones, which are caused by human error. Reading and capturing the data should be done with caution. Additionally, proper error calculation is required. We can lower the obvious errors by increasing the number of experimenters. We can lessen the gross errors by taking the average of many readings if each researcher takes separate readings at different points.

2. Random Errors:

The errors classified as random are ones that happen erratically. These can develop as a result of erratic and unpredictable changes in the experimental environment (for instance, unpredictably changing temperature, voltage supply, mechanical vibrations of the experimental setups, etc., observer errors when obtaining readings, etc.). The numerous kinds of measuring errors were examined in this article. Every measurement we take contains these flaws.

3. Systematic Errors:

If we break systematic errors down into subgroups, we can better understand them.

These subgroups are:

• Environmental Errors
• Observational Errors
• Instrumental Errors

Environmental Errors:

This kind of measurement inaccuracy develops as a result of how the measurement is impacted by the outside environment. Along with temperature, pressure, and humidity, the external state may also contain an external magnetic field. If you take your temperature under the armpits, your body temperature will change during the measurement if the power goes out or the room becomes hot. Your temperature reading will fluctuate as a result.

Observational Errors:

These are the mistakes that result from bias on the part of the observer, improper instrument setup, or carelessness during taking observations. The measurement errors also include incorrect readings brought on by refraction errors.

Instrumental Errors:

The measurement instruments' poor design and calibration are to blame for these mistakes. These mistakes happen as a result of friction or the hysteresis of the machinery. Frequently, the equipment in use is malfunctioning as a result of misuse or neglect, causing the equipment's reading to shift. One extremely typical kind of error is the zero error. Devices like Vernier callipers and screw gauges frequently make this mistake. Either a positive or negative zero mistake is possible. A poor reading might also result from the scale's readings becoming worn out from use.

Instrumental error takes place due to :

An inherent constraint of devices

Misuse of Apparatus

Effect of Loading
