The fx column in a Frequency Distribution Table is the frequency (f) multiplied by the Class Centre or score (x).

If the score is 22.

And the freqency for that score is 7.

fx = 22*7 = 154

You can use the total of the fx column to find the mean.

The total fx divided by the total frequency = Mean.

How do you find fx from the given frequency table?

You multiply the number in the "X" column (the event column) by the corresponding number in the Frequency column (i.e the "how many times the event happended" column).If you have a frequency table, showing how many red cars were spotted in consecutive hours on the same stretch of road: Let "X"=number of red cars. (Please imagine the lines of the table, data is the same style in each column, i.e bold is X, italic is F and plain is Fx. )X FrequencyX=1 10X=2 2X=3 4X=4 3This data shows that the total number of hours spent watching for red cars was 19 (the total of the F column). It also shows that on 10 occasions, only one red car was seen per hour, on 2 occasions only 2 red cars were seen per hour etc...Now Fx is the value in the X column multiplied by the frequency, i.e:X Frequency FxX=1 10 10X=2 2 4X=3 4 12X=4 3 12Total Fx is the number of red cars seen in total: 38

What is domain and range of random variable?

Let S denote the sample space underlying a random experiment with elements s 2 S. A random variable, X, is defined as a function X(s) whose domain is S and whose range is a set of real numbers, i.e., X(s) 2 R1. Example A: Consider the experiment of tossing a coin. The sample space is S = fH; Tg. The function X(s) = ½ 1 if s = H ¡1 if s = T is a random variable whose domain is S and range is f¡1; 1g. Example B: Let the set of all real numbers between 0 and 1 be the sample space, S. The function X(s) = 2s ¡ 1 is a random variable whose domain is S and range is set of all real numbers between ¡1 and 1. A discrete random variable is one whose range is a countable set. The random variable defined in example A is a discrete randowm variable. A continuous random variable is one whose range is not a countable set. The random variable defined in Example B is a continiuos random varible. A mixed random variable contains aspects of both these types. For example, let the set of all real numbers between 0 and 1 be the sample space, S. The function X(s) = ½ 2s ¡ 1 if s 2 (0; 1 2 ) 1 if s 2 [ 1 2 ; 1) is a mixed random variable with domain S and range set that includes set of all real numbers between ¡1 and 0 and the number 1. Cummulative Distribution Function Given a random variable X, let us consider the event fX · xg where x is any real number. The probability of this event, i.e., Pr(X · x), is simply denoted by FX(x) : FX(x) = Pr(X(s) · x); x 2 R1: The function FX(x) is called the probability or cumulative distribution fuction (CDF). Note that this CDF is a function of both the outcomes of the random experiment as embodied in X(s) and the particular scalar variable x. The properties of CDF are as follows: ² Since FX(x) is a probability, its range is limited to the interval: 0 · FX(x) · 1. ² FX(x) is a non-decreasing function in x, i.e., x1 < x2 Ã! FX(x1) · FX(x2): 1 ² FX(¡1) = 0 and FX(1) = 1. ² For continuous random variables, the CDF fX(x) is a unifromly continuous function in x, i.e., lim x!xo FX(x) = FX(xo): ² For discrete random variables, the CDF is in general of the form: FX(x) = X xi2X(s) piu(x ¡ xi); x 2 R1; where the sequence pi is called the probability mass function and u(x) is the unit step function. Probability Distribution Function The derivative of the CDF FX(x), denoted as fX(x), is called the probability density function (PDF) of the random variable X, i.e. fX(x) = dF(x) dx ; x 2 R1: or, equivalently the CDF can be related to the PDF via: FX(x) = Z x ¡1 fX(u)du; x 2 R1: Note that area under the PDF curve is unity, i.e., Z 1 ¡1 fX(u)du = FX(1) ¡ FX(¡1) = 1 ¡ 0 = 1 In general the probability of a random variable X(s) taking values in the range x 2 [a; b] is given by: Pr(x 2 [a; b]) = Z b a fX(x)dx = FX(b) ¡ FX(a): For discrete random variables the PDF takes the general form: fX(x) = X xi2X(s) pi±(x ¡ xi): Specifically for continuous random variables: Pr(x = xo) = FX(x+ o ) ¡ FX(x¡o ) = 0: 2


Casio fx 115 es vs fx991es?

They are the same thing, Casio calls it FX-115ES in some countries, such as the U.S., and FX-991ES in most other countries. I believe this has to do with model name recognition. "FX-115" has been used in various U.S. models for a long time.


The domain of Fx is the set of all numbers greater than or equal to 0 and less than or equal to 2?

Depends on what Fx is.

How do you solve for variable fx in statistics?

It depends on whether fx denotes frequency times variable value or the probability generating function for the variable x.
