Question

To conduct a t-test, you need all scale variables (ratio or
interval).
True
False

Answer 1

True

Explanation:

A t-test is a statistical test used to determine whether there is a significant difference between the means of two groups of data. To conduct a t-test, you need data that is measured on a scale variable, which can be either ratio or interval.

Ratio variables have a true zero point, such as height, weight, and age. Interval variables do not have a true zero point, such as temperature measured in Fahrenheit or Celsius. Both types of scale variables can be used in a t-test, as long as the data meets the assumptions of normality, independence, and homogeneity of variance.
