What is megalencephaly?
Megalencephaly (also called macrencephaly) describes an enlarged brain whose weight exceeds the mean (the average weight for that age and sex) by at least 2.5 standard deviations (a statistical measure of variation).
How do you explain the analysis of variance assuming that your audience has not had a statistic class before?
The measurement of any statistical variable will vary from one observation to another. Some of this variation is systematic - due to variations in some other variable that "explains" these variations. There may be several such explanatory variables - acting in isolation or in conjunction with one another. Finally, there will be a residual variation which cannot be explained by any of these "explanatory" variables. The statistical technique called analysis of variance first calculates the total variation in the observations. The next step is to calculate what proportion of that variation can be "explained" by other variables, and finding the residual variation. A comparison of the explained variation with the residual variation is an indicator of whether or not the amount explained is statistically significant. The word "explain" is in quotes because there is not always a causal relationship. The causality may go in the opposite direction. Or the variables may be related to another variable that is not part of the analysis.
What is the statistical analysis of population trends called?
It is called demographics.
When two quantities form a direct variation what is it called?
A direct variation (!) or direct reelationship.
What is the set of input values called?
In a statistical context this is usually called a sample.

Why do you sometimes repeat readings three times in science?
Performing a measurement or an experiment three-times is called a triplicate. Triplicate results make statistical analysis better and prevent the possibility of unusual results due to natural/artificial variation.
What system of measurement?
The worldwide system of measurement is called SI (short for Système international d'unités). It is a variation of the metric system.

What is measure of variation?
A measure of variation, also called a measure of dispersion, is a type of measurement that details how a set of data is scattered from a central or neutral point of origin. Range, variance and standard deviation are three measures of variation that are commonly used.
What is the statistical analysis of population trends called?
It is called demographics.
What is variation among members of the same species called?
Intraspecific variation
