Data Set

A collection of related data collected from a single source.

Model

A function which is used to represent a problem, and which can be used to solve the problem.

Zero Slope

This is the slope of a horizontal line. The line has no vertical change between each horizontal change.

Mean

This is the sum of all the results included in the sample, divided by the number of observations.

Trend

This is the relationship between two sets of data.

Correlation

In a set of data, if there is no clear pattern to the points when graphed on a coordinate plane, we say there is no relative __________.

Rate

The amount of increase or decrease in a function.

Line Graph

A graph that is represented by points connected by segments.

Tendency

These are statistics that describe the center of a distribution: mean, median, mode. The measure central ________.

Line

This is the straight path connecting two points and extending infinitely in both directions.

Interpolate

This is the process of predicting values for points which occur BETWEEN those given in a set of bivariate data.

Table

This is an arrangement of data, usually in rows and columns. It is called a __________.

Range

This is the difference between the maximum and the minimum value in a data set.

Extrapolate

To look at known values and make an estimation based on observations.

Data

When gathering information for research, we say we are collecting _________.

Extend

To continue a given pattern to a desired number of terms.

Y-Intercept

This is a point at which a graph intersects the y-axis.

Predict

This is what you do when you use information or data to make an informed guess about what will happen in the future.

Range

The output of a function or relation. The set of y-values that a graph is defined on.

Data

Numbers or facts that describe something. It can be numerical, counted, or descriptive.

Interquartile Range

The spread of the middle 50% of the data.
