Interval Estimate
Interval Estimate refers to a range of values, derived from sample statistics, used to estimate a population parameter.
Standard Error
Measures the accuracy with which a sample represents a population, showing the dispersion of sample means around the true population mean.
Test Statistic
A standardized value derived from sample data during a hypothesis test that is used to determine the p-value or to compare against the critical value.
Population Means
The average value of a set of characteristics or figures for the entire population.
