AP Stats Chapter 1 Voc and Concepts

Statistics is

• the science and art of collecting, analyzing, and drawing conclusions from data

• • are objects described by a set of data. Individuals may be people, but they

    may also be animals or things.

• • is any characteristic of an individual. A variable can take different values for

    different individuals.

• 0. in any graph of data is an individual observation that falls outside the overall pattern of the graph.

• • Arrange all observation in order of size, from smallest to largest.

• • is any characteristic of an individual. A variable can take different values for

    different individuals.

• • places an individual into one of several groups or categories.

• • takes numerical values for which arithmetic operations such as

    adding and averaging make sense.

• 0. of a variable tells us what values the variable takes and how often it takes these variables.
