One Sample t Statistic for Mean Formula Elements

Variables

t Statistic

t Statistic is the value obtained from a t-test, which compares the means of two groups to determine if they are significantly different.

Symbol: t

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find t Statistic

Sample Mean

Sample Mean is the average of a set of values from a sample. It provides an estimate of the population mean and is a statistic because it describes the sample and is calculated from sample data.

Symbol: x̄

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Sample Mean

Population Mean

Population Mean is the average of all the values in a population. It represents the central tendency of the entire group and is a parameter because it describes the entire population.

Symbol: μ_Population

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Population Mean

Standard Error

Standard Error is the measure of the variability of sample statistics, particularly the sample mean. It quantifies the precision of the sample mean as an estimate of the population mean.

Symbol: SE

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.
