Levels of Measurements
Miscellaneous
100
A researcher observes and measures characteristics or interest of part of a population but does not change existing conditions.
What is Observational Study?
100

A count or measure of an entire population.

Census?

100
Three key elements of a well-designed experiment.
What are Control, Randomization, and Replication.
100
Qualitative only. Data can be categorized using names, labels, or qualities.
What is Nominal Measurement?
100
The collection of all outcomes, responses, measurements, or counts that are of interest.
What is Population?
200
Is applied to part of a population, called a treatment group, and response are observed.
What is Treatment?
200
A count or measure of part of a population.
What is Sampling?
200
Occurs when a subject reacts favorably to a placebo when in fact the subject has been given a fake treatment.
What is The Placebo Effect.
200
Are qualitative or quantitative. Data can be arranged in order, or ranked.
What is Ordinal Measurement?
200
Is a subset, or part, of a population.
What is a Sample?
300
No treatment is applied
What is Control Group?
300
The difference between the results of a sample and those of the population.
What is Sampling Error?
300
Helps control or minimize the placebo effect.
What is Blinding?
300
Can be ordered, and meaningful differences between data entries can be calculated. At this level, a zero represents a position on a scale.
What is Interval Measurement?
300
A numerical description of a population characteristic.
What is a Parameter?
400
The subjects in the treatment and control group.
What is Experimental Units?
400
One in which every member of of the population has an equal chance of being selected.
What is Random Sample?
400
Neither the experimenter nor the subjects know if the subject are receiving a treatment or a placebo.
What is Double-blind Experiment?
400
Similar to data at the interval level, but that a zero entry is an inherent zero.
What is Ratio Measurement?
400
A numerical description of a sample characteristic.
What is a Statistic?
500
A harmless, fake treatment, that is made to look like the real treatment.
What is Placebo?
500
A sample in which every possible sample of the same size has the same of being selected.
What is Simple Random Sample?
500
Groups of subjects with similar characteristics.
What is Blocks?
500
A zero that implies "none".
What is an Inherent Zero?
500
Consists of information coming from observations, counts, measurements, or responses.
