	Mean value theorem - Wikipedia, the free encyclopedia
		In calculus, the mean value theorem states, roughly, that given a section of a smooth curve, there is a point on that section at which the derivative (slope) of the curve is equal to the "average" derivative of the section.
		The mean value theorem can be used to prove Taylor's theorem, of which it is a special case.
		Thus the Mean value theorem says that given any chord of a smooth curve, we can find a point lying between the end-points of the chord such that the tangent at that point is parallel to the chord.

	Learning Resources: Statistics: Power from Data! Calculating the mean
		The mean of a numeric variable is calculated by adding the values of all observations in a data set and then dividing that sum by the number of observations in the set.
		As was mentioned in the soccer tournament example, the accuracy of the approximation of the mean will depend on how close each of the girls is to the midpoint of her interval.
		Therefore, the mean height of the 50 girls in Grade 10 is 164.5 cm.

	Arithmetic mean - Wikipedia, the free encyclopedia

		The arithmetic mean is greatly influenced by outliers.
		The arithmetic mean of those rises is 10 %, but since the stock rose by $5.1 in 2 years, an average of 8.1 % would result in the final $35.1 figure [$30(1-10 %)(1+30 %) = $30(1+8.1 %)(1+8.1 %) = $35.1].

		The mean value theorem states that under the specified hypotheses, there is a point in the interval of interest such that the slope of the tangent line at that point is equal to the slope of the secant line connecting the two endpoints of the graph of the function.
		In other words, the average rate of change of the function f on the interval [a, b] is equal to the instantaneous rate of change of the function f at some point c in (a, b).
		To find the value of c given in the Mean Value Theorem, we need to find a tangent line to the curve that has the same slope as the secant line.

	How to Calculate Geometric Means
		A geometric mean, unlike an arithmetic mean, tends to dampen the effect of very high or low values, which might bias the mean if a straight average (arithmetic mean) were calculated.
		Because of how geometric mean is calculated, the precise substitution value generally does not appreciably affect the result of the calculation, and ensures that all the data remains usable.
		For example, to calculate the geometric mean of the values +12%, -8%, and +2%, instead calculate the geometric mean of their decimal multiplier equivalents of 1.12, 0.92, and 1.02, to compute a geometric mean of 1.0167.

	Mean, Variance and Distributions
		Two measures of the prospects provided by such a portfolio are assumed to be sufficient for evaluating its desirability: the expected or mean value at the end of the accounting period and the standard deviation or its square, the variance, of that value.
		In addition, it is assumed that the values are drawn from a sample distribution taken from a larger population., and that the variance and standard deviation of the population are to be estimated.
		where p(x) is proportional to the probability that the actual value will equal x; ev and sd stand for the expected value and standard deviation, respectively, of the distribution, and nd is the deviation of x from ev in standard deviation units.

		Verify that the function satisfies the hypotheses of the Mean Value Theorem on the given interval.
		I expect that in your textbook the conditions given for the Mean Value Theorem are either that "f(x) is differentiable for all x in [a,b]" or that "f(x) is differentiable for all x in (a,b) and continuous for all a in [a,b]".
		The conclusion of the Mean Value Theorem is that somewhere on the curve between P and Q there is a point where the tangent line is parallel to the line joining P and Q. The first coordinate of this point is the number "c" in your problem.

	What is a P value?
		The P value is a probability, with a value ranging from zero to one.
		If the P value is 0.03, that means that there is a 3% chance of observing a difference as large as you observed even if the two population means are identical.
		You happened to randomly obtain larger values in one group and smaller values in the other, and the difference was large enough to generate a P value less than the threshold you set.
