The important mutually exclusive predictions to test, how statistical tests should be designed, and what control groups are appropriate, will be specific to each individual investigation.
When members of two independent groups can fall into one of two mutually exclusive categories, Fisher Exact test is used to determine whether the proportions of those falling into each category differs by group.
These possibilities are not necessarily mutually exclusive and await testing in future studies.
Because KRAS and NRAS mutations are mutually exclusive, NRAS mutation testing should be performed when KRAS is wild-type.
Two alternative but not mutually exclusive hypotheses were tested: a) one or more of the types of gonadal malformations induced by atrazine represented "demasculinization" or loss of androgens, and/or b) one or more of the types of gonadal malformations represented feminization as a result of inappropriate estrogen production.
In our opinion these two alternatives are not mutually exclusive and should be tested in the future.
Step 6: Validation and testing: multiple mutually exclusive samples of ED cases along with synthetic/real positive BTA cases were utilized to perform 10-fold cross-validation as well as testing to generate statistical measures such as positive predicted value, negative predicted value, sensitivity, specificity, accuracy and receiver operating characteristic curve (ROC) for each BTA.
The stimuli presented in the two testing sessions were mutually exclusive so that subjects were not re-exposed to any previously viewed stimuli during the first test that would aid them in retest performance.
Mutually exclusive character states were used to test if gene flow had ceased between the sampled populations [ 35].
With the amount and complexity of intra-genome phylogenetic signal emerging from investigations to date, it is critical to apply rigorous tests of explicit, mutually exclusive hypotheses to explain conflicts among gene trees.
Comparison of diagnostic efficacy parameters between mutually exclusive subgroups was performed with Fisher's exact test.
