Question

Quizplus · Accepted Answer

The t ratio (or t value) is calculated by dividing the difference between the sample mean and the population mean by the estimated standard error. If the estimated standard error decreases, the denominator in this calculation becomes smaller, which makes the t ratio larger, assuming the numerator remains constant.
