The variability hypothesis, also known as the greater male variability hypothesis, is the hypothesis that males generally display greater variability in traits than females do. It has often been discussed in relation to human cognitive ability , where some studies appear to show that males are more likely than females to have either very high ...
Thorndike greatly influenced the work of Leta Hollingworth as he was a supporter of the variability hypothesis. The variability hypothesis postulated that, because men exhibit a greater variation in both psychological and physical traits than women, women were destined for mediocrity while men both occupied the highest and lowest ends of the ...
Bateman's principle, in evolutionary biology, is that in most species, variability in reproductive success (or reproductive variance) is greater in males than in females. It was first proposed by Angus John Bateman (1919–1996), an English geneticist. Bateman suggested that, since males are capable of producing millions of sperm cells with ...
Leta Hollingworth was a clinical psychologist and feminist activist who conducted psychological research on several theories involving women. Some of these theories included the variability hypothesis and functional periodicity. She was quite instrumental in disproving the theory of functional periodicity, which was widely believed to be true ...
Variability hypothesis, nineteenth century hypothesis that males have a greater range of ability than females; Variable (disambiguation) Variable renewable energy, a renewable energy source of a fluctuating nature; Variance, a specific measure of statistical dispersion; Variation (disambiguation)
The Spectral Variability Hypothesis (SVH) states that spatial variability in the reflectance of vegetated surfaces relates to plant species richness.It has been originally coined by Palmer et al. (2000) and states that "species richness will be positively related to any objective measure (e.g. standard deviation) of the variation in the spectral characteristics of a remotely sensed image".

An example of Neyman–Pearson hypothesis testing (or null hypothesis statistical significance testing) can be made by a change to the radioactive suitcase example. If the "suitcase" is actually a shielded container for the transportation of radioactive material, then a test might be used to select among three hypotheses: no radioactive source ...
All terms require hypothesis tests. The proliferation of interaction terms increases the risk that some hypothesis test will produce a false positive by chance. Fortunately, experience says that high order interactions are rare. [41] [verification needed] The ability to detect interactions is a major advantage of multiple factor ANOVA. Testing ...
