Data Sets
100
Data at this level can be arranged in order or ranked, but differences are not meaningful.
What is ordinal
100
A study in which a researcher does not influence the responses
What is observational study
100
when an experimenter cannot tell the difference between the effects of different factors on the variable
What is confounding variable
100
a sample that is not a representative of the population from which its drawn
What is biased sample
100
the collection of all outcomes responses measurements or counts that are of interest
What is population
200
Data at this level are categorized using names, labels, or qualities.
What is nominal
200
A study in which a researcher deliberately applies a treatment before observing the responses
What is an experiment
200
a technique where the subjects do not know whether they are receiving a treatment or a placebo
What is blinding
200
a count or measure of the entire population
What is census
200
a subset or part of a population
What is sample
300
Can be ordered, and meaningful differences between data entries can be calculated.
What is interval
300
A harmless fake treatment that is made to look like a real treatment
What is a placebo
300
a process of randomly assigning subjects to different treatment groups
What is randomization
300
a count or measure of part of a population more commonly used in statistical studies
What is sampeling
300
a numerical description of a population characteristic
What is parameter
400
similar to data at the interval level, with the added property that a zero entry is an inherent zero.
What is ratio
400
the use of mathematical of physical models to reproduce the conditions of the situation or process
What is simulation
400
groups of subjects with similar characteristics
What is blocks
400
when a study is done with faulty data
What is sampling error
400
a numerical description of a sample characteristic
What is statistic
500

What is ordinal
500
an investigation of one or more characteristics of a population
What is survey
500
subjects are paired up according to similarity
What is matched pairs design
500
a type of sample that often leads to biased studies
What is convenient sample

consists of information coming from observations, counts, measurements, or responses
