If three dice are tossed, a trial is one toss of one die and the experiment is composed of three trials.

If the response variable is expected to follow a parametric family of probability distributions, then the statistician may specify ( in the protocol for the experiment or observational study ) that the responses be transformed to stabilize the variance.

::" If anyone imagines that we are stating the case too strongly, let him try an experiment with the first bright boy he meets by asking,

If there are T treatments and T – 1 orthogonal contrasts, all the information that can be captured from the experiment is obtainable from the set of contrasts.

If morning rush traffic can be heard from outside, if researchers or maintenance staff appear at the same time each day, an experiment can be ruined by masking.

Since counter-clockwise may be defined in terms of up, forward, and right, this experiment unambiguously differentiates left from right using only natural elements: If they were reversed, or the atoms spun clockwise, the radiation would follow the spin axis instead of being opposite to it.

If the aether was dragged by mass then this experiment would have been able to detect the drag caused by the lead, but again the null result was found.

If at any time the subject indicated his desire to halt the experiment, he was given a succession of verbal prods by the experimenter, in this order:

If the subject still wished to stop after all four successive verbal prods, the experiment was halted.

If, in some future experiment, one of the mass-related phenomena is shown to not be proportional to the others, then that specific phenomenon will no longer be considered a part of the abstract concept of mass.

If a random experiment can result in N mutually exclusive and equally likely outcomes and if N < sub > A </ sub > of these outcomes result in the occurrence of the event A, the probability of A is defined by

If one throws a die once, it is difficult to predict the outcome, but if we repeat this experiment many times, we will see that the number of times each result occurs divided by the number of throws will eventually stabilize towards a specific value.

If that happens, Franks said, “... the Western world, the free world, loses what it cherishes most, and that is freedom and liberty we ’ ve seen for a couple of hundred years in this grand experiment that we call democracy .” Franks then offered “ in a practical sense ” what he thinks would happen in the aftermath of such an attack.

If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results.

In 2002, psychologist Richard Wiseman and colleagues at the University of Hertfordshire, UK, finished a year-long LaughLab experiment, concluding that of all animals, ducks attract the most humor and silliness ; he said, " If you're going to tell a joke involving an animal, make it a duck.

If outcomes of different runs of an experiment differ in any way that matters, they are distinct outcomes.

If Randall ’ s claim that the host may chase off possible dangers to the cleaner will be proved right, an experiment might be constructed in which reciprocity could be demonstrated.

If we modify this experiment so that one slit is closed, no interference pattern is observed.

If an experiment is carefully conducted, the results usually either support or disprove the hypothesis.

If the experiment is repeated with other colors, the color which has a majority will still rarely win.

If the experiment is repeated using approval voting, where voters are encouraged to vote for as many candidates as they approve of, then the winner is much more likely to be any one of the five marbles, because people who prefer green will be able to vote for every one of the green marbles.

If the subjects in the experiment are suspicious of the researcher, they are unlikely to behave as they normally would, and the researcher ’ s control of the experiment is then compromised ( p. 807 ).

In a 1975 retrospective article, Gold commented that his policy with If was to experiment, using new writers that had not yet established themselves.

If she, Pamela, were being held responsible for his crimes, then hers must be the final act of expiation.

If we were creating a wholly new society, we could insist that our social, political, economic and philosophic institutions foster rather than hamper man ; ;

If living Jews were unavailable for study, the Bible was at hand.

If his scholarship and formal musicianship were not all they might have been, Mercer demonstrated at an early age that he was gifted with a remarkable ear for rhythm and dialect.

If anything, the conservative Democrats were more opposed to Hearst than the Republicans.

If the hardships of the winter at Valley Forge were trying for healthy men, they were, of course, much more so for those not in good health.

If his circumspection in regard to Philip's sensibilities went so far that he even refused to grant a dispensation for the marriage of Amadee's daughter, Agnes, to the son of the dauphin of Vienne -- a truly peacemaking move according to thirteenth-century ideas, for Savoy and Dauphine were as usual fighting on opposite sides -- for fear that he might seem to be favoring the anti-French coalition, he would certainly never take the far more drastic step of ordering the return of Gascony to Edward, even though, as he admitted to the English ambassadors, he had been advised that the original cession was invalid.

If there were no West Berlin problem, imperialist quarters would have invented an excuse for stepping up the armaments race to try to solve the internal and external problems besetting the United States and its NATO partners.

If the new Soviet series has followed the general pattern of previous Russian tests, the shots were roughly half fission and half fusion, meaning a fission yield of 30 to 40 megatons thus far.

If the Hessian troops sent here willy-nilly by the Hessian Government to fight for England in the 1770's were mercenaries, what shall we call the UN troops sent to the Congo willy-nilly by their governments to fight for the United Nations??
