Sentence examples for different variance t-tests from inspiring English sources

Based on the genes selected with different variance t-tests and SAM statistics, Relief was used to rank these genes with WEKA 3.4.

In cases of equal sample variance, t-tests were performed (two-tailed), and where variances between groups were significantly different, a Welch correction was applied.

Hence, parametric t-tests are always pooled variance t-tests.

When Levene's test indicated unequality of variance, t-tests without assumed equal variances were performed.

These averages are significantly different, with an unequal variance T-test P-value of 10-2.

These algorithms incorporate genes differentially expressed among different classes as assessed by the random variance t-test.

The Class Comparison analyses were performed using BRB ArrayTools [ 17] developed by Dr. Richard Simon and Amy Peng Lam to determine if gene expression profiles were different between groups by applying a random variance t-test to the data.

An unequal variance t-test was used as the samples had different variances.

aUnequal variance t test.

‡By the equal variance t test.

For samples with normal distributions but different variances, the t test was adjusted using Welch's correction.
