This branch of statistics involves the organization, summarization, and display of data
What is Descriptive Statistics
100
This is a numerical description of a sample characteristic
What is a Statistic
100
Data at this level of measurement can be arranged in order, or ranked, but differences between data entries are not meaningful
What is Ordinal Level of Measurement
100
A part of the population where no treatment is applied during an experiment
What is a Control Group
100
This is a numerical description of a population characteristic
What is a Parameter
200
Data at this level of measurement is can be ordered, and meaningful differences between data entries can be calculated. This data does not have an inherent zero.
What is Interval Level of Measurement
200
A process of randomly assigning subjects to different treatment groups
What is Randomization
200
This is a subset, or part, of a population
What is a sample
200
This data consists of numerical measurements or counts
What is Quantitative Data
200
A harmless, unmedicated treatment, that is made to look like the real treatment
What is a Placebo
300
The collection of all outcomes, responses, measurements, or counts that are of interest
What is population
300
Th repetition of an experiment under the same or similar conditions
What is Replication
300
A technique where neither the experimenter nor the subjects know if the subjects are receiving a treatment or placebo
What is a Double-Blind Experiment
300
The science of collecting, organizing, analyzing, and interpreting data in order to make decisions
What is Statistics
300
A technique where the subjects do not know whether they are receiving a treatment or placebo
What is Blinding
400
An investigation of one or more characteristics of a population
What is a Survey
400
This consists of information coming from observations, counts, measurements, or responses
What is data
400
The use of a mathematical or physical model to reproduce the conditions of a situation or process
What is a Simulation
400
Data at this level of measurement is categorized using names, labels, or qualities. No mathematical computations can be made at this level
What is Nominal Level of Measurement
400
This is the branch of statistics that involves using a sample to draw conclusion about a population
What is Inferential Statistics
500
The count or measure of an entire population
What is a Census
500
Data at this level of measurement can be ordered, and meaningful differences between data entries can be calculated. This data has an inherent zero.
What is Ratio Level of Measurement
500
This data consists of attributes, labels, or nonnumerical entries
What is Qualitative Data
500
Where a treatment is applied to part of a population and responses are observed
What is an Experiment
500
A study in which a researcher observes and measures characteristics of interest of part of a population but does not change exiting conditions
