How to Find Means
In the previous post we have discussed about Explain permutation and combination and In today's session we are going to discuss about How to Find Means. In this blog we are going to learn about the mean. In statistics mean is define the average value for the given set of numbers .These numbers are in arbitrary form means these numbers are not in the specific order. The mean value for the given set of numbers is defined as average value in general. Usually we calculate the arithmetic mean of the numbers that are given in form of average value of these numbers. (know more about Means, here)
There is also one other type of mean that is known s the populated mean that define the expected value for the defined random variable.
When we talk about the arithmetic mean it is define the average as follows:
If there are given a data set as p1, p2, p3, p4 and p5 then the arithmetic mean is calculated by using the formula as
Average (arithmetic mean) = sum of all the numbers in the data set / number of values
So according to the formula mean = p1 + p2 + p3 + p4 + p5 / 5
In statistics there are mainly three types of mean values are defined that are as follows:
(1): Arithmetic mean
(2): Geometric mean
(3): Harmonic mean
In geometric mean we can calculate the mean value for the given data set by multiplying the number rather than adding these numbers .there are basically define the values that are define in terms of rates as birth rate or mortal rate or growth rate etc.
Geometric mean = (p1 * p2 * p3 * p4 * p5) > 1/5
Harmonic mean is used to define the average value in terms of determining the relation with respect to some unit as acceleration that is defined as speed in per unit time.
Multiplying polynomials helps student to understand the way how polynomials are multiplied in easy manner. CBSE chemistry syllabus provided by the CBSE board that guides the student about the topics covered in the particular session.
