Data will be collected on the following variables. Which variable can be considered discrete?

Dependent and independent variables are variables in mathematical modeling statistical modeling and experimental sciences.Dependent variables receive this name because in an experiment their values are studied under the supposition or hypothesis that they depend by some law or rule (e.g. by a mathematical function) on the values of other variables .

In mathematics a variable may be continuous or discrete. If it can take on two particular real values such that it can also take on all real values between them (even values that are arbitrarily close together) the variable is continuous in that interval. If it can take on a value such that there is a non-infinitesimal gap on each side of it containing no values that the variable can take on then it is discrete around that value. In some contexts a variable can be discrete in some ranges of the number line and continuous in others.

A statistical model is a mathematical model that embodies a set of statistical assumptions concerning the generation of sample data (and similar data from a larger population).A statistical model represents often in considerably idealized form the data -generating process. A statistical model is usually specified as a mathematical relationship between one or more random variables and other …

Discrete time views values of variables as occurring at distinct separate “points in time” or equivalently as being unchanged throughout each non-zero region of time (“time period”)—that is time is viewed as a discrete variable .Thus a non-time variable jumps from one value to another as time moves from one time period to the next. This view of time corresponds to a digital clock that …

Random variables can be discrete that is taking any of a specified finite or countable list of values (having…
