The null distribution of this statistic is calculated under the null hypothesis that the samples are drawn from the same distribution ( in the two-sample case ) or that the sample is drawn from the reference distribution ( in the one-sample case ).

Note that the two-sample test checks whether the two data samples come from the same distribution.

An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass.

The product of two " beat tracks " of slightly different speeds overlaid, producing an audible moiré pattern ; if the beats of one track correspond to where in space a black dot or line exists and the beats of the other track correspond to the points in space where a camera is sampling light, because the frequencies are not exactly the same and aligned perfectly together, beats ( or samples ) will align closely at some moments in time and far apart at other times.

If parasitic effects are significant, point-to-point wiring has the disadvantage compared to a PCB of indeterminate parasitic components ; while the inductance and capacitance due to a PCB are the same for all samples, values may vary between point-to-point wired units, changing circuit operation.

It was released by Interplay in 1997, featuring a new super deformed style for the characters ( the original version kept the same art style as the first game ) as well as voiced dialogue samples.

The JFIF standard requires samples to be sited " interstitially " — meaning the decoder can treat each component array as representing an array of equal-sized rectangular pixels sampled in their centers, with each array having the same exterior boundaries as the image.

The symposium provides an opportunity to confront the self with specific statements which were made at particular times by identifiable communicators who were addressing definite audiences -- and throughout several hundred pages everyone is talking about the same key symbol of identification.

In much the same way, we recognize the importance of Shakespeare's familarity with Plutarch and Montaigne, of Shelley's study of Plato's dialogues, and of Coleridge's enthusiastic plundering of the writings of many philosophers and theologians from Plato to Schelling and William Godwin, through which so many abstract ideas were brought to the attention of English men of letters.

He could no longer build anything, whether a private residence in his Pennsylvania county or a church in Brazil, without it being obvious that he had done it, and while here and there he was taken to task for again developing the same airy technique, they were such fanciful and sometimes even playful buildings that the public felt assured by its sense of recognition after a time, a quality of authentic uniqueness about them, which, once established by an artist as his private vision, is no longer disputable as to its other values.
