The uniform distribution describes probabilistic properties of a continuous random variable that is equally likely to take any value within an interval , and never takes on values outside this interval.
The uniform distribution is characterised by two parameters – the lower and the upper boundaries of the interval ( and in our example).
Mathematically, the uniform distribution is described by its probability density described by the following expression:
The uniform distribution describes, for example, the distribution of errors arising after rounding floating point numbers up to the nearest integer, e.g. in course of analog-to-digit conversion taking place whenever a physical entity, like an image or sound signal, is converted to a digital form.
Planning on taking an introductory statistics course, but not sure if you need to start at the beginning? Review the course description for each of our introductory statistics courses and estimate which best matches your level, then take the self test for that course. If you get all or almost all the questions correct, move on and take the next test.
