Variables
These types of variables describe a group
What is Categorical
This statistical test compares the means of two groups.
That is a T test
This is the type of research where variables are manipulated to determine cause and effect.
What is experimental
This sampling method gives every individual in a population an equal chance of being selected
What is random
In experimental design, this variable is manipulated by the researcher
What is the independent variable
This type of variable has a true zero and can calculate percentage.
What is Ratio
This is the probability that a statistical result occurred by chance, often set at 0.05 or lower.
What is the P value
This is the most common form of non-experimental research where data is collected without manipulating variables and deals with the relationships of those variables
What is correlational research
This is the assumption that there is no effect or no difference between groups in a study.
What is the Null hypothesis
In hypothesis testing, this error occurs when a true null hypothesis is incorrectly rejected
What is a type 1 error
This is the type of variable that can take on a range of values and can be divided into smaller parts
What is continuous
This is the most common measure of central tendency, calculated by summing values and dividing by the number of values.
What is the mean
This type of study follows participants over a long period to observe long-term outcomes.
What is longitudinal
This is the name of the bell-shaped curve that represents a normal distribution of data.
What is a normal curve
Before conducting human research, a proposal typically must be approved by this review board.
What is an institutional review board. (IRB)
This is the variable in an experiment that is measured to determine the effect of manipulation.
What is dependent variable
This type of bias occurs when the sample is not representative of the population.
What is sampling bias
This method involves an in-depth, detailed examination of an individual or a small group over a period of time.
What is a case study
This is the statistic used to describe the strength and direction of the relationship between two variables
What is a correlation coefficient
This type of validity refers to how well a test measures what it claims to measure.
This methodology systematically synthesizes the findings of multiple studies to answer a specific research question, often through statistical techniques
What is Meta Analysis
This is a method used to reduce a large number of variables into fewer, interpretable factors.
What is factor analysis
This is the type of research design where different participants are tested in separate groups for the same variable.
What is between subject design.
This research approach combines both quantitative and qualitative methods to provide a more comprehensive analysis
What is a mixed method design
This type of reliability refers to the consistency of a measure when the same test is given at different times.
What is test-retest reliability
