If you have a constant sweet taste in your mouth, itâs possible you have taste impairment, meaning thereâs a problem with your ability to taste. There are many reasons for taste impairment, including a nasal infection, cold, or flu.
Discrete vs. Continuous Variables. Quantitative variables can be further classified as discrete or continuous. If a variable can take on any value between its minimum value and its maximum value, it is called a continuous variable; otherwise, it is called a discrete variable.
The probability that a continuous random variable takes a value in a given interval is equal to the integral of its probability density function over that interval, which in turn is equal to the area of the region in the xy-plane bounded by the x-axis, the pdf and the vertical lines corresponding to the boundaries of the interval.
