hypothesis
A hypothesis is a proposed explanation for a phenomenon
Internal validity
In scientific research, internal validity is the extent to which a causal conclusion based on a study is warranted, which is determined by the degree to which a study minimizes systematic error
Simple linear regression
In statistics, simple linear regression is a linear regression model with a single explanatory variable
linear regression
In statistics, linear regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables denoted X
statistic
Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data
hypothesis test
A statistical hypothesis is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables
descriptive
In the study of language, description or descriptive linguistics is the work of objectively analyzing and describing how language is actually used by a group of people in a speech community
inferential
Statistical inference is the process of deducing properties of an underlying distribution by analysis of data
correlation coefficient
A correlation coefficient is a number that quantifies some type of correlation and dependence, meaning statistical relationships between two or more random variables or observed data values
