Levels of Measurement
100

SSD is the acronym for 

Single Subject Design

100

This allows for evaluation across clients, situations or problems

Multiple Baseline Design

100

Level of measurement that begins with the the letter N

Nominal

200
B design is used for this only

Intervention

200

A period of time during which an outcome is measured repeatedly in the absence of the intervention

Baselining

200

Measurement type that begins with the letter O

Ordinal

300

A two phase design consisting of a no-intervention baseline

AB Design

300

These three measurement patterns are present in the baseline phase

Stable Line Trend Cycle

300

Two things we strive for in measurement?

Accuracy and Consistency

400

This design is more reliable establishment of a relationship between intervention and outcome than in the AB design

ABA Design

400

These three things are the situations that arise when no pattern is evident

Measures are unreliable

Inconsistencies in reporting

Changes in client's life

400

This level of measurement includes a zero

Scale

500

This design allows the researcher to begin with an intervention 

BAB Design

500

Four key characteristics of all measures

Validity Reliability Measurement error Utility
