The rejection of a null hypothesis that is actually true
What is Type I Error
The difference between what really exists and what is measured in a study
What is Measurement Error?
Procedures that combine mathematical processes and logic to test hypotheses about a population with the help of sample data.
What is Inferential Statistics?
Paper-and-pencil instruments designed to gather data from individuals about knowledge, attitudes, beliefs, and feelings
What is Questionnaire?
The systematic use of data to monitor the outcomes of care processes, as well as the use of improvement methods to design and test changes in practice for the purpose of continuously improving the quality and safety of health care systems
What is Quality Improvement?
The tendency for statistics to fluctuate from one sample to another
Level used to classify objects or events into categories without any relative ranking (e.g., gender, hair color)
What are Nominal Measurements?
Statistical methods used to describe and summarize sample data.
What are Descriptive Statistics?
A type of interview where the researcher directly asks study participants questions with the intent of utilizing the responses in the study.
What is a Self-Report Questionnaire?
A method that scientifically describes cultural groups. The goal is to understand the native’s view of their world.
What is Ethnographic?
This type of error occurs when scores vary in a random way.
What is Random Error?
A descriptive statistical procedure that describes the average member of a sample (mean, median, and mode)
What are Measures of Central Tendency?
Quantifies the uncertainty of a statistic or the probable value range within which a population parameter is expected to lie.
What is Confidence Interval?
The phenomenon where the study participants change behavior because they know they are being observed.
What is Reactivity?
Steps in qualitative research to ensure accuracy, validity, or soundness of data.
What is Credibility?
This type of error occurs when scores are all incorrect in the same direction
What is Systematic Error?
Level used to show rankings of events or objects; numbers are not equidistant, and zero is arbitrary (e.g., class ranking)
What is an Ordinal Measurement?
The degree of association between two variables
What is Correlation?
A study in which the relationship between two or more variables is examined.
A small, simple study conducted as a prelude to a larger-scale study that is often called the “parent study.”
What is a Pilot Study?
What is Type II error?
The process of assigning numbers to variables or events according to rules
What is Measurement?
A statistic that tests whether group means differ from each other, rather than testing each pair of means separately. It considers the variation among all groups.
What is ANOVA?
A study type that examines data at one point in time.
Variable that interferes with the operations of the phenomena being studied.
What is an Extraneous Variable?
