Is a discrete variable normally described as a word?
No.A discrete variable is a variable that can not assume all possible values within a given range.For example, if I were to conduct a survey on the number of children people had, then my answers would be numbers such as 0, 1, 2 and so forth (i.e. they would be whole numbers). This particular variable could not have a value in between these (a non integer value), such as 1.345, as this makes no sense in this context. This makes the variable discrete.
Is movie reviews a discrete variable?
I would have to say so, since there are fixed units assigned (stars and half stars) and a limited number of responses possible. If you could give any amount of stars ( like 2.923 stars) then it would not be a discrete variable.
What is a dicrete variable?
A discrete variable is a variable that has a certain set limit. For example, a ten point scale can ONLY have the variables 1, 2, 3, 4, 5, 6, 7, 8, 9, & 10. 2.8 would not work on a discrete variable ten point scale. Height is an example of a continuous variable, or one that has an infinite possibility.
Difference between continuous and discrete variables?
Continuous variable is one like temperature, and discrete variable are ones like male and female. So if you are looking at temperatures between 90 and 100 degrees, there is an infinite number of them. Say between 99 and 99.1, we have 99.05 and between that and 99 we have 99.005 etc. The variable is continuous because it can take on any value between 90 and 100. But if you are talking about gender, than it is either male of female and not continuous. Having said all this, now we define a continuous variable A continuous is one for which, within the limits the variable ranges, any value is possible. So what about time? If the variable is how long it take to read this answer, is that discrete? NO, it is continuous. A five point scale is an example of a discrete variable.
What would the integer be of a rolled number cube?
It could be a random variable with a discrete uniform distribution over the range 1 to 6.
