Question

Quizplus · Accepted Answer

A one-sample t test requires interval or ratio level of measurement on the variable being tested. This is because the test is used to compare the mean of a sample to a known population mean, and the calculation of the t-statistic requires the use of interval or ratio data. Nominal and ordinal data do not provide the necessary level of precision for this type of analysis.
