Discrete variables must be countable and not negative. So no a negative number must be a continuous variable.

A random variable that can assume only a finite number of values is referred to as?
That would be a discrete variable; or, in your case, it would probably be called a discrete random variable.
What does a graph look like if there is no relationship between variables?
A rather random zig-zag, probably.
What is the strongest linear correlation?
The relationship between two random independently distributed variables is considered to be theoretically the weakest when the correlation coefficient is zero and theoretically the strongest when the correlation coefficient is one, indicating a positive relationship between two variables and negative one, indicating a negative relationationship between two variables. I state that this is a theoretical result as if variables are not random, independently distributed, then a high correlation coefficient can result. For example, let us say that we obtained the following data on age and frequency of accidents: Age 18 1 in 18 people have accidents in a year Age 25 1 in 25 people have accident in a year Age 30 1 in 30 people have accidents in a year Age 35 1 in 6 people have accidents. Age 40 1 in 400 people have accidents If I selectively calculated a correlation coefficient this data including only the three groups ages 18, 25 and 30, you can see I will have a correlation coefficient of 1, however the data was not a random sample of all ages.

What are the symbols used in quadratic equations?
Addition, subtraction signs, brackets, squares and powers, square roots and roots, fractions. Random variables are also used, like x.
What is the rule 8 15 52 4 9 17 71 6 22 0?
It is a collection of random non-negative integers ordered by their spelling in English.
Should there be equal steps between values in discrete random variables?
Not necessarily.
What has the author Wai Wan Tsang written?
Wai Wan Tsang has written: 'Analysis of the square-the-histogram method for generating discrete random variables' -- subject(s): Random variables
Is the gender of college students a discrete random variable a continuous random variable or not a random variable?
It is a discrete random variable.
What is the definititon of a discrete random variable?
The discrete random variable almost always arises in connection with counting.
What is meant by discrete random variable?
A discrete random variable is a variable that can only take some selected values. The values that it can take may be infinite in number (eg the counting numbers), but unlike a continuous random variable, it cannot take any value in between valid results.
Is the number of pills in a container of vitamins discrete or continuous?
Discrete random variable
Can a discrete variable be a negative number?
Yes. For example, consider rolling a die twice, with the random variable defined as the first outcome minus the second.
Why are important in random variables?
It might help if you specified why WHAT was important in random variables.
Can the Poisson distribution be a continuous random variable or a discrete random variable?
True
What is the difference between a discrete and continuous random variable?
· A variable whose values are determined by the outcomes of a random experiment is called a random variable. A random variable is a discrete random variable if it can assume values, which are finite or countable infinite. For example, tossing of a die is a random experiment and its outcomes 1, 2, 3, 4, 5 and 6 are discrete random variable. When a coin is tossed, its outcomes head and tail are discrete random variable. Three coins are thrown; the number of heads is example of discrete random variable. Note that the outcomes need ot be integers or even numbers (eg colour of eyes). · If a random variable can assume every possible value in an interval [a, b], a< b, where a and b may be - infinity and + infinity respectively, for example, the points on number line between 0 and 1; Value of 'x' between 0 and 2; Number of heads on a coin when it is tossed infinite times.
Is the number of statistics students now reading a book discrete or continuous?
The random variable is discrete
A random variable that can assume only a finite number of values is referred to as?
