· Dependent variable ( student's academic achievement ) : It depend on the way that we use it to write the score (if we write it as a letter it will be an ordinal ,but if we write it as number it will be an interval). · Independent variable ( intelligent ) : Interval, · Independent variable ( attention ) : Interval,
Yes. Simply make sure that the interval is greater than or equal to the range of the random variable.
Yes, it is a Continuous variable measured along an equidistant scale.

Variable-interval schedule (VI) is a reinforcement schedule in which reinforcement is provided for the first response that occurs after a variable amount of time from the last reinforcer or the start of the trial interval.

different between variable intervals and fixed ratio
Nothing, but you can speak about the lifetime of a variable: the time-interval in which the variable exists.

A Body has variable speed if it covers unequal distance in equal interval of time is known as Variable Speed
A variable measured at the interval or ratio level can have more than one arithmetic mean.

It can be though more often it is a variable on the interval scale (when looking for trends over time).
