In marketing and business intelligence, A/B testing is a term for a randomized experiment with two variants, A and B, which are the control and variation in the controlled experiment.

A/B testing is a form of statistical hypothesis testing with two variants leading to the technical term, two-sample hypothesis testing, used in the field of statistics.

Other terms used for this method include bucket tests and split.run testing.

These terms can have a wider applicability to more than two variants, but the term A/B testing is also frequently used in the context of testing more than two variants.

In online settings, such as web design (especially user experience design), the goal of A/B testing is to identify changes to web pages that increase or maximize an outcome of interest (e.g., click-through rate for a banner advertisement).

Formally the current web page is associated with the null hypothesis.

A/B testing is a way to compare two versions of a single variable typically by testing a subject's response to variable A against variable B, and determining which of the two variables is more effective.

Customer service is the provision of service to customers before, during and after a purchase.

The perception of success of such interactions is dependent on employees "who can adjust themselves to the personality of the guest".

Market segmentation is the process of dividing a broad consumer or business market, normally consisting of existing and potential customers, into sub-groups of consumers (known as segments) based on some type of shared characteristics.

In dividing or segmenting markets, researchers typically look for shared characteristics such as common needs, common interests, similar lifestyles or even similar demographic profiles.

The overall aim of segmentation is to identify high yield segments – that is, those segments that are likely to be the most profitable or that have growth potential – so that these can be selected for special attention (i.e. become target markets).

Knowledge management (KM) is the process of creating, sharing, using and managing the knowledge and information of an organization.

It refers to a multidisciplinary approach to achieving organisational objectives by making the best use of knowledge.

The piano is an acoustic, stringed musical instrument invented around the year 1700 (the exact year is uncertain), in which the strings are struck by hammers.

It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings.

The word piano is a shortened form of pianoforte, the Italian term for the early 1700s versions of the instrument, which in turn derives from gravicembalo col piano e forte and fortepiano.

The Italian musical terms piano and forte indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the greater the velocity of a key press, the greater the force of the hammer hitting the strings, and the louder the sound of the note produced and the stronger the attack.

The first fortepianos in the 1700s had a quieter sound and smaller dynamic range.
