Probability-An important topic in statistics

 welcome guys,

Suppose,some one asked to you that,"I want to do course on statistics,What you think it will be useful for me?


Then you replied that yes,I think so,there is 80% chance that you will get the  successful job careers with that...

What this chance scientifically called in statistics?Any guess...?

Yes,you are absolutely correct,its nothing but the "probability"

Sometimes we use word  "probably" in many situations...This word indicating that you are not sure about something...This same happens in many situations and problems....

The mathematical methods of probability invented due fair division of stake in an interrupted game of chance and it is firstly invented by Gerolamo Cardano in 1560s(not published until 100 years later) and corresponded by De Fermat and Pascal later...

Let us consider the following definition about probability...

Event can be defined as outcome or collection of outcome of an random experiment...


Probability

When we unsure about the outcome of an event,then we talk about the probability of certain outcome.The probability of event is the ratio of number of cases favorable to it to the number of all possible cases.
 
In other words, probability of event A is denoted by P(A) and is defined as 
If A can happen in m ways out of a total n equally likely ways then 
P(A)=m/n.

Thanks for reading...

Median

Image
  Median Median is the value of the variable that divides the ordered set of values into two equal parts. In another words,median is the middle most value of ordered( ascending or descending)set of values.50% of values are to the left side of the median and 50% values are on right side of the median. let us consider there are N values in the data set. I)when N is odd,then  Median=size of(N+1/2) th item(Arranging values in ascending or descending order) Example:  values =1,2,3,4,5 here,Median is 3 II) when N is even , median is the average of size of (N/2)th item and (N+2/2) th item. Example: Heights (in cm) = {180, 167, 154, 122, 181, 135, 123, 145, 166, 145} Rearranged Heights= {122, 123, 135, 145, 145, 154, 166, 167, 180, 181} Median = (145+154)/2 = 149.5= 149.5 Median is preferable measure of location for asymmetric distribution.Median is best measure of central tendency as it is least affected by extreme values.Median can be visually located for discrete values....

Mode

Image
Mode : Mode is an important measure of central tendency.Ya Lun Chou statement about the mode is ,"Mode is that values of series which appears most frequently than any other." In simple  words,"The mode is a value which has highest frequency." The mode may not be unique .that is there are several values or classes with the same highest frequency. I) Mode for discrete data:      Mode of sample is the observation with highest frequency. Example: A sample is 4,8,3,8,3,9,3,7,11,3,12,11 Here number 3 has maximum frequency(4). Hence given sample has mode 3. II)Mode for grouped data:      Mode of grouped data is the class centre of the modal class,while the modal class is a class which has highest frequency. Example Here 10-20 class has maximum frequency (15). Hence 10-20 is modal class. Here L=10,f1=15,fo=5,f2=8,h=20-10= 10 Mode=10+[(15-5)/(30-5-8)]×10 Mode=10+(10/17)×10 Mode=10+5.88 Mode=15.88 For example,In clothing Store,they operate their business to incl...

Sample space and event in probability

Image
  Sample space and Event Sample space:  A collection of all possible outcomes of an experiment is called sample space.It is denoted by  Ω. Example: A coin is tossed   Ω ={H,T} Where H=head, T=tail.   Event: The collection of all outcomes favorable to phenomenon is called an event. It is denoted by capital letters A,B,C.. Example: Event A is containing at least one head,if two coins are tossed.   Ω ={HH,HT,TH,TT} A={HH,HT,TH} (1) Elementary event: An event containing only one element is called as elementary or simple event. Example: Event A is getting both heads ,if two coins are tossed.   Ω ={HH,HT,TH,TT} A={HH} (2) Compound event: An event which contains more then one sample point of sample space is called a compound event. Example: Event A is containing both head and tail,if two coins are tossed. Ω ={HH,HT,TH,TT} A={HT,TH} (3)Sure event or certain event: An event containing all the points of sample space is called sure event. Example:  In an exp...
