t-test for means
A variable measured at the interval or ratio level can have more than one arithmetic mean.
Interval notation is a method of writing down a set of numbers. An example of this is all numbers that are greater than five.Ê
Time is ratio data because it has a true, meaningful data. You can say that at time 20 seconds, it is twice the amount of time than 10 seconds. Interval data doesn't have a true zero e.g. degrees celcius. Although you can say 60 degrees is hotter than 30 degrees you can't say that it is twice as hot.
