Perform a Sample T-test on SPSS

Sample T-test: Examines the evidence that the dependent variable is influenced in a meaningful way by the independent variable; if it is, then it is statistically significant.

Variable: An element, feature, or factor that is liable to vary or change.

Independent Variable: This variable varies from each statistical test and influences the dependent variable.

Dependant Variable: The variable that will be measured and affected by the independent variable.

When to use it: The sample t-test is used to examine whether a sample comes from a particular population when the full population information is not available.

Sample: Part of a population that is a reasonable size to be analyzed (i.e. a set of 1,000 people given a survey out of a population of 200,000).

Population: The overall group that a sample is taken from. It usually can’t be represented directly, but instead is represented indirectly through analysis of a sample.
