Bias is any trend or deviation from the truth in data collection, data analysis, interpretation and publication which can cause false conclusions. Every scientist should therefore be aware of all potential sources of bias and undertake all possible actions to reduce and minimize the deviation from the truth.

The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. Even the best-intentioned scientists can’t escape bias. It results from personal beliefs, as well as cultural beliefs, which means any human filters information based on his or her own experience.

Scientists are keen to avoid bias of any kind because they threaten scientific ideals such as objectivity, transparency and rationality. Such awareness is commonly seen as a crucial step towards making science objective, transparent and free from bias.

Understanding research bias is important for several reasons: first, bias exists in all research, across research designs and is difficult to eliminate; second, bias can occur at each stage of the research process; third, bias impacts on the validity and reliability of study findings and misinterpretation of data can …

Bias is an inclination toward (or away from) one way of thinking, often based on how you were raised. For example, in one of the most high-profile trials of the 20th century, O.J. Simpson was acquitted of murder. Many people remain biased against him years later, treating him like a convicted killer anyway.

The tendency to judge in favor of people and symbols we like is called the bias from liking or loving. We are more likely to ignore faults and comply with wishes of our friends or lovers rather than random strangers. We favor people, products, and actions associated with our favorite celebrities.

We hear the word ‘bias,’ and we say it’s bad or wrong,” Ross said. “In reality, bias can be bad or wrong … but it can also be tremendously helpful.” One example of an instance in which bias is helpful, said Ross, is when someone is approached by a stranger with a knife in their hand.

A person who is influenced by a bias is biased. The expression is not “they’re bias,” but “they’re biased.” Also, many people say someone is “biased toward” something or someone when they mean biased against. To have a bias toward something is to be biased in its favor.

Bias means that a person prefers an idea and possibly does not give equal chance to a different idea. Facts or opinions that do not support the point of view in a biased article would be excluded. For example, an article biased toward riding a motorcycle would show facts about the good gas mileage, fun, and agility.

The English language develops about 1000 new words a year, but dictionaries exhibit bias by delaying or refusing to incorporate conservative words or expressions like “invisible hand”, “term limits,” “Rule of Law,” and “strict constructionism.”

Bias is direct current ( DC ) deliberately made to flow, or DC voltage deliberately applied, between two points for the purpose of controlling a circuit . In a bipolar transistor , the bias is usually specified as the direction in which DC from a battery or power supply flows between the emitter and the base.

Biasing is the process of providing DC voltage which helps in the functioning of the circuit. A transistor is based in order to make the emitter base junction forward biased and collector base junction reverse biased, so that it maintains in active region, to work as an amplifier.

In electronics, biasing is the setting of initial operating conditions (current and voltage) of an active device in an amplifier. This current or voltage is a bias. The AC signal applied to them is superpositioned on this DC bias current or voltage.

Types of bias circuit for class-A amplifiers

• Fixed bias.
• Collector-to-base bias.
• Fixed bias with emitter resistor.
• Voltage divider bias or potential divider.
• Emitter bias.

TYPES OF BIASING There are two main classes of biasing—FIXED and SELF. In a tube circuit that uses fixed bias, the grid-bias voltage is supplied from a power source external to the circuit. You are already familiar with battery bias, which is one form of fixed bias.

Because it receives the most current carriers, it generates more heat than all other regions. The collector region is the largest of all regions because it must dissipate more heat than the emitter or base regions. The larger area ensures that it has more surface area to dissipate heat.

The doping level of collector is intermediate between the heavy doping of emitter and the light doping of the base. The collector is so named because it collects electrons from base. The collector is the largest of the three regions; it must dissipate more heat than the emitter or base.

Emitter is always forward biased w.r.t base so as to supply majority charge carriers to the base.
