What is the difference between a random variable and random process?
A random process is a sequence of random variables defined over a period of time.
What make a number sequence?
A number sequence is an ordered set of numbers. There can be a rule such that the next number in the sequence can be determined by the values of some or all of the preceding terms in the sequence. However, the sequence for a random walk illustrates that such a rule is not necessary to define a sequence.
How do you define a variable?
I define an variable by saying x- an value
In Statistics define the 4 ARMC criteria?
1. variable is an antecedent 2. random assignment 3. values are maniipulated 4. controls
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 is the probability that the random variable has a value less than 5?
That depends on the rules that define the random variable.
What is the difference between a random variable and random process?
A random process is a sequence of random variables defined over a period of time.
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.

Define continuous random evevt?
Usually we consider a random variable which assigns a value to the outcome of an event. The value assigned to the outcome can be either discrete or continuous. The continuous random variable is a random variable whose domain is defined over a continuous range. Examples: Daily inches of rain, speed of cars on highway, purchases made everyday at grocery stores.

I define an variable by saying x- an value

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
How do mathematicians define a variable?
They define a variable by saying n equals some value.
