Null Hypothesis

The default assumption in statistical testing that there is no effect or no difference, aiming to be either rejected or not rejected based on the data analysis.

Z Test

A statistical test used to determine if there is a significant difference between a sample mean and a population mean, assuming data is normally distributed.

Standard Error

Standard error measures the precision of a sample mean estimate of a population mean, indicating how much the sample mean is expected to fluctuate from the true population mean.

Population Average

The mean value of a given characteristic within an entire population.
