Numerical description of a population

What is a statistic?
100
Data that is not influenced by the researcher
What is observational study?
200
Collection of all outcomes or responses
What is population?
200
Measurement that is qualitative or quantitative
What is ordinal level of measurement?
200
A count or measure of an entire population
What is a census?
200
Involves using a sample to draw conclusions about a population
What is inferential statistics?
200
Where a researchers deliberately applies a treatment before recording data
What is an experiment?
300
Part of a population
What is sample?
300
Measurement that can be ordered, and meaningful differences between data entries can be calculated
What is interval level of measurement?
300
The difference between the results of a sample and those of a population
What is a sampling error?
300
information about qualities; information that can't actually be measured.
What is qualitative data?
300
A fake treatment
What is placebo?
400
Consists of information coming from observations, counts, measurements, or responses
What is data?
400
Measurement that are similar to data at the interval level, with the added property that a zero entry is an inherited zero.
What is ratio level of measurement?
400
In which every possible sample of the same size has the same chance of being selected
What is a simple random sample?
400
Data expressing a certain quantity, amount or range. Usually, there are measurement units associated with the data.
What is quantitative data?
400
Process of randomly assigning subjects to different treatment groups
What is randomization?
500
Involves the organization, summarization, and display of data
What is descriptive statistics?
500
A zero that implies "none"
What is inherent zero?
500
Where subjects are paired up based on similarity
What is a matched-pairs design?
500
The repetition of an experiment under the same conditions
What is replication?
500
Occurs when an experimenter cannot tell the difference between the effects of different factors on the variable
What is confounding variable?
