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 ...
Like the origin of language, the origin of music has been a topic for speculation and debate for centuries. [3] Leading theories include Darwin's theory of partner choice (women choose male partners based on musical displays), the idea that human musical behaviors are primarily based on behaviors of other animals (see zoomusicology), the idea that music emerged because it promotes social ...
In statistical quality control, the individual/moving-range chart is a type of control chart used to monitor variables data from a business or industrial process for which it is impractical to use rational subgroups. [1] The chart is necessary in the following situations: [2]: 231
Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.
If someone is listening to music with the ultimate goal of completing a task, their musical preference is greatly increased. The more a genre of music increases one's productiveness, the more the individual will gravitate toward that genre to complete future tasks. [43] In turn, music can increase focus in some.
According to Nattiez, Boretz "seems to be confusing his own formal, logical model with an immanent essence he then ascribes to music," and Babbitt "defines a musical theory as a hypothetical-deductive system ... but if we look closely at what he says, we quickly realize that the theory also seeks to legitimize a music yet to come; that is, that ...
Statistical hypothesis testing is founded on the assessment of differences and similarities between frequency distributions. This assessment involves measures of central tendency or averages , such as the mean and median , and measures of variability or statistical dispersion , such as the standard deviation or variance .
Information visualization is also a hypothesis generation scheme, which can be, and is typically followed by more analytical or formal analysis, such as statistical hypothesis testing. To communicate information clearly and efficiently, data visualization uses statistical graphics , plots , information graphics and other tools.
