What is convenience sampling?
100
Practice that based on current scientific evidence.
What is evidence-based practice?

What is median?
100
The arithmetic average of a group being studied.
What is mean?
200

What is a blinding study?
200
The risk of committing a type I error.
What is level of significance?
200
An aspect of a population that is difficult or impossible to measure.
What is parameter?

What is alternative time sampling?
200
A distortion of evidence or data that arises from the way the data was collected.

What is quantitative analysis?
400
Error that results from observation of a sample rather than a whole population.
What is sampling error?
400
An exact statement that the results are a chance of variation (the opposite of the hypothesis).
What is null hypothesis?
400
A subset of individuals chosen from a larger set; a sample chosen randomly and entirely by chance.
What is a random sample?
400
Numeral facts or data that do not try to infer anything about a subject that goes beyond the data can be qualitative or quantitative.
What are descriptive statistics?
400
Variables that can make drawing accurate conclusions from a study difficult.
What are nuisance variables?
500
Failure to accept the alternative hypothesis when the alternative hypothesis was true.
What is type II error?
500
A descriptive term used when the observed phenomenon represents a significant departure from what might be expected by chance alone.
What is statistically significant?
500
The number that occurs more often than any other number in a set of data.
What is mode?
500
A large group of people or places or objects that are the main focus of a scientific query.
What is population?
500
A research specification by which all parties are mad aware of the study, treatment, and outcome to be measured.
