What else can I help you with?
Is the random variable x equals 1 be stated that the random variable is discrete?
If x = 1 then X is not really a random variable but a constant.
What the deference between variable and variate?
A random variate is a particular outcome of a random variable: the random variates which are other outcomes of the same random variable would have different values.
Can the Poisson distribution be a continuous random variable or a discrete random variable?
True
What is the difference between random variable and random process?
A random variable is a variable which can take different values and the values that it takes depends on some probability distribution rather than a deterministic rule. A random process is a process which can be in a number of different states and the transition from one state to another is random.
How often the value of a random variable is at or below a certain value?
How often the value of a random variable is at or below a certain value.
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.
When random variable is variable?
When it is random it is variable.
Is the random variable x equals 1 be stated that the random variable is discrete?
If x = 1 then X is not really a random variable but a constant.
What the deference between variable and variate?
A random variate is a particular outcome of a random variable: the random variates which are other outcomes of the same random variable would have different values.
Can the Poisson distribution be a continuous random variable or a discrete random variable?
True
A variable whose value is a numerical outcome of a random phenomenon is called?
random variable.
Is the expected value of a discrete random variable equal to the mean of the random variable?
yes?
What is the difference between random variable and random variate?
Random variables is a function that can produce outcomes with different probability and random variates is the particular outcome of a random variable.
What type of variable has an unpredictable impact on the dependent variable?
A random variable.
What is a random variable?
A random variable is a function that assigns unique numerical values to all possible outcomes of a random experiment. A real valued function defined on a sample space of an experiment is also called random variable.
Random variable that can take any numeric value within a range of values?
continuous random variable
What is the definititon of a discrete random variable?
The discrete random variable almost always arises in connection with counting.
What is the probability that the random variable has a value less than 5?
That depends on the rules that define the random 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 is the difference between random variable and random process?
A random variable is a variable which can take different values and the values that it takes depends on some probability distribution rather than a deterministic rule. A random process is a process which can be in a number of different states and the transition from one state to another is random.
How often the value of a random variable is at or below a certain value?
How often the value of a random variable is at or below a certain value.
What is measured by the numerator of the z-score test statistic?
The z-score, for a value z, is the probability that a Standard Normal random variable will have a value greater than z.
What is a random variable in probability theory?
Random Variable in probability theory is defined as follows: Assuming you have variables Xi where i is an integer ie: i=1,2,3.......n a variable Xi is called a random variable iff(if and only iff) and random selection yields a variable Xi for i=1,2.........,n with the same likelihood of appearance. i.e prob(X=Xi)=1/n
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.
How do you find the z score of 12.5?
To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
