⩥ average rate of change.
Answer: The average rate at which one variable is changing in relation
to another variable's changing.
⩥ big-box stores.
Answer: A very large store, typically over 50,000 square feet, of plain
design, resembling a large box.
⩥ broadband.
Answer: High-speed Internet access that is always on and much faster
than dial-up.
⩥ calculate the average rate of change.
Answer: The formula to compute an average rate of change is (y2-y1)
divided by (x2-x1).
⩥ coefficient of determination.
,Answer: A statistic that measures how well a regression predictions
approximate the real data points. An r^2 of 1 indicates that the
regression prediction is a perfect fit for the data.
⩥ common era.
Answer: A designation previously called "A.D.," meaning annus domini,
"year of the Lord"; the Common Era dates year 1 as the presumed year
of Jesus of Nazareth's birth.
⩥ common ratio.
Answer: The number by which each term in a sequence is multiplied to
find the next number in the sequence; for example 4 is the common ratio
for the sequence [1, 4, 16, 64, 256...].
⩥ constant ratio.
Answer: Occurs when the numeric relationship between two quantities -
that is, how many times one number contains the second - remains
unchanged over time.
⩥ data.
Answer: A collection of facts, which might be numbers, words,
measurements, observations or simply descriptions.
⩥ data regression.
, Answer: The process of examining data points to determine a valid
equation. "Regression" refers to bringing different data points down
toward a normal average - "regressing" them.
⩥ dependent variable.
Answer: A variable that is changed by another variable (called the
independent variable); for example, when a person is purchasing gas, the
cost (the dependent variable) rises as more gas is pumped into a car's
tank (the independent variable).
⩥ equations.
Answer: A mathematical statement that two things are equal; it consists
of two expressions, one on each side of an equals sign.
⩥ exponent.
Answer: A mathematical notation - a superscript - that defines the
number of times a number is multiplied by itself.
⩥ exponential function.
Answer: A function that has an extremely rapid increase or decrease in
quantity in proportion to its current value; its form is f(x) = b^2.
⩥ extrapolation.
