Levels of Measurement
100
a technique where the subjects do not know whether they are receiving a treatment or a placebo
What is blinding
100
a count or measure of an entire population
What is cenus
100
the collection of all outcomes, responses, measurements, or count that are of interest.
What is population
100
consists of attributes,labels, or nonnumerical entries.
What is qualitative data
100
data that is categorized using names, labels, or qualities.
What is the nominal level of measurement
200
the process of randomly assigning subjects to different treatment groups.
What is randomization
200
a count or measure of a part of a population and is more commonly used in statistical studies
What is sampling
200
a subset, or part, of a population
What is sample
200
consist of numerical measurements or counts
What is quantitative data
200
Data that can be arranged in order, or ranked, but differences between data entries are not meaningful
What is ordinal level of measurement
300
Groups of subjects with similar characteristics
What is blocks
300
the difference between the results of a sample and those of a population
What is sampling error
300
a numerical description of a population characteristic
What is parameter
300
data that can be ordered, and meaningful differences between data entries can be calculated
What is interval level of measurement
400
occurs when an experimenter cannot tell the different between the effects of different factors on the variable
What is confounding variable
400
one in which every member of the population has an equal chance of being selected
What is a random sample
400
a numerical description of a sample characteristic
What is statistic
400
the science of collecting, organizing, analyzing, and interpreting data in order to make decisions
What is statistics
400
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 level of measurement
500
The repetition of an experiment under the same or similar conditions
What is replication
500
a sample in which every possible of the same size has the same chance of being selected
What is a simple random sample
500
consist of information coming from observations,counts,measurements, or responses
What is data
500
The branch of statistics that involves using a sample to draw conclusions about a population
What is Inferential statistics
