From the 1980s a new series of statistical tests had been tried.

We considered a p value less than 0.05 to be significant for all statistical tests.

A number of statistical tests have been developed to study such relations.

The statistical test is performed again, now including all 4n subjects.

Statistical tests are made on the basis of these assumptions.

Statistical tests are sensitive to the nature of the input data.

Also, it is unclear whether the correct statistical tests were used.

Many researchers say that results don't count unless they pass the statistical tests.

That is difficult, because the study used complex statistical tests to determine genuine ability.

In table 3 of the paper we present all the data from the study with the results of the standard statistical tests.
