Key Calculus Terms and definitions covered in this textbook
• Blocking

A feature of some experimental designs that controls for potential differences between subject groups by applying treatments randomly within homogeneous blocks of subjects

• Categorical variable

In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

• Conditional probability

The probability of an event A given that an event B has already occurred

• Derivative of ƒ

The function defined by ƒ'(x) = limh:0ƒ(x + h) - ƒ(x)h for all of x where the limit exists

• Equilibrium price

See Equilibrium point.

• First-degree equation in x , y, and z

An equation that can be written in the form.

• Horizontal line

y = b.

• Inequality symbol or

<,>,<,>.

• Linear regression equation

Equation of a linear regression line

• Linear regression line

The line for which the sum of the squares of the residuals is the smallest possible

• Multiplication principle of probability

If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(A|B) # P(B)

• nth root

See Principal nth root

• One-to-one function

A function in which each element of the range corresponds to exactly one element in the domain

• Polar coordinates

The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

• Positive linear correlation

See Linear correlation.

• Probability distribution

The collection of probabilities of outcomes in a sample space assigned by a probability function.

A procedure for fitting a quadratic function to a set of data.

• Right angle

A 90° angle.

• Root of an equation

A solution.

• Standard representation of a vector

A representative arrow with its initial point at the origin
