Statistics

Back 1

The study of methods for describing and interpreting quantitative information, which is called data

Front 2

Variability

Back 2

Dissimilarity in scores and outcomes obtained under the same circumstances

Front 3

Causes of Variability

Back 3

Individual Differences, Measurement Error, and Unreliability

Front 4

Categories of Statistics

Back 4

Descriptive and Inferential

Front 5

Descriptive Statistics

Back 5

Refers to procedures for organizing,summarizing and describing data

Front 6

Inferential Statistics

Back 6

Includes methods for making inferences on a larger group of individuals based on data collected from a smaller group

Front 7

Measurement

Back 7

Orderly assignment of a numerical value to a characteristic

Front 8

What procedures are used to describe and draw inferences from measurements or quantitative information or data?

Back 8

Statistical Procedures

Front 9

Scale of Measurement

Back 9

The ordered set of possible numbers that may be obtained by the measurement process

Front 10

Properties of a Scale

Back 10

Rank Order, Categorization or Rating, Magnitude, Equal Intervals, or Absolute Zero

Front 11

Magnitude

Back 11

Occurs when the attribute being measured can be judged greater than, less than, or equal to another instance of the attribute

Front 12

Equal Intervals

Back 12

Occurs when the magnitude of the attribute represented by a unit of measurement on the scale is the same regardless of where on the scale the unit falls

Front 13

Absolute Zero Point

Back 13

A value which indicates that nothing at all of the attribute being measured exists

Front 14

Ratio Scale

Back 14

Scale of measurement with magnitude, equal intervals, and an absolute zero point

Front 15

Interval Scale

Back 15

Scale of measurement with magnitude and equal intervals but no absolute zero point

Front 16

Ordinal Scale

Back 16

Scale of measurement with only magnitude and no properties of equal interval or an absolute zero point

Front 17

Nominal Scale

Back 17

Scale of measurement that classifies items into mutually exclusive groups that do not have any magnitude relations

Front 18

Name quantitative scale(s)

Back 18

Ratio and Interval Scales

Front 19

Name qualitative scale(s)

Back 19

Ordinal and Nominal Scales

Front 20

Which scale of measurement contains magnitude, equal intervals and an absolute zero point?

Back 20

Ratio Scale

Front 21

Which scale of measurement possesses none of the properties of scales?

Back 21

Nominal Scale

Front 22

Which scale of measurement only contains magnitude?

Back 22

Ordinal Scale

Front 23

Which scale of measurement contains magnitude and equal intervals only?

Back 23

Interval Scale

Front 24

Variable

Back 24

General characteristic being measured that has the ability to vary

Front 25

Constant

Back 25

A quantity that does not change it value within a given context

Front 26

Discrete Variable

Back 26

A variable that can assume only countable number of values between any two points

Front 27

Continuous Variable

Back 27

A variable that theoretically can assume an infinite number of values between any two points on the measurement scale

Front 28

Real Limits

Back 28

Points of a number falling one-half measurement unit above and one-half measurement below that number
