Levels of measurement
100
Occurs when an experiment cannot tell the difference between the effects of different factors on the variable.
What is Confounding variables
100
A count or measure of an entire population
What is Census
100
observing and measuring characteristics of interest of part of a population but does not change existing conditions
What is observational studies
100
Consists of attributes, labels, or non-numerical entries
What is qualitative data
100
data at this level are catagorized using names, labels, or qualities
What is nominal measure
200
A technique where the subjects do not know whether they are receiving a treatment or placebo.
What is Blinding
200
A count or measure of part of a population, and is more commonly used in statistical studies
What is Sampling
200
This is when a researcher deliberately applies a treatment before observing the responses
What is Experiment
200
Consists of numerical measurements or counts
What is quantitative data
300
A process of randomly assigning subjects to different treatment groups
What is Randomization
300
The difference between the results of a sample and those of the population
What is Sampling error
300
A harmless fake treatment that is made to look like the real treatment
What is Placebo
300
data at this level can be arranged in order, or ranked, but difference is between data entries are not meaningful
What is ordinal measure
400
The repetition of an experiment under the same or similar conditions
What is Replication
400
One in which every member of the population has an equal chance of being selected
What is Random sample
400
The use of a mathematical or physical model to reproduce the conditions of a situation or process
What is simulation
400
the subset, or part, of a population
What is sample
400
at this level a zero entry simply represents a position on a scale; the entry is not an inherent zero
What is interval measure
500
Neither the experimenter nor the subjects know if the subjects are receiving a treatment or a placebo
What is Double-blind experiment
500
A sample in which every possible sample of the same size has the same chance of being selected
What is Simple random sample
500
An investigation of one or more characteristics of a population
What is survey
500
Numerical description of a populations characteristics
What is Parameter
500
a ratio of two data entries can be formed so that one data entry can be meaningfully expressed as a multiple of another
What is ratio measure
