However, the null result indicated something was wrong with the concept.

A test of this claim a year later yielded null results.

However, if the same null result still stands at this time next year, many more experts are likely to be surprised.

But he had blown his cover by announcing the null result far too early.

However, his experiments were duplicated many times, always with a null result.

The next figure shows what empirical tests of this hypothesis have found: a null result.

If the trial was stopped when expected, then the null result would have not been clinically useful.

In carefully designed scientific experiments, even null results can be evidence of absence.

Baker must have thought that meant a null result.

A null result would suggest that humans might be alone in the galaxy or the universe.

Thus there are only two possibilities, given a null result:

"It really gives us confidence that we're going to be finding planets rather than a null result," he said.

A series of experiments using similar but increasingly sophisticated apparatus all returned the null result as well.

This allows one to deduce that X cannot be present if a null result is received.

This was what we call a "null result" for their speed-of-light experiments.

Null result is a term often used in the field of science to indicate evidence of absence.

They confirmed the null result of the initial experiment.

One of the first was the University of Washington, who reported a null result in 1991.

Yet these "null results" are often just as important to science as those demonstrating a positive finding.

Several studies of prayer effectiveness have yielded null results.

In the context of good palliation, the null result is still of value.

So the writer is obliged to point out that null results can have far-reaching scientific importance.

The null result would surely incite a great deal of debate and, perhaps, consternation.

A null result is incompatible with a causal hypothesis.

This correction was successful in explaining the null result of Arago's experiment.
