Data: Figure of numerical form or information or Numerical information about something. there basically two type of data. Qualitative and Quantitative. Qualitative is private information regarding qualitative variable, attributes such as honesty, colour, sex etc. Quantitative is two types continue and discrete. Continue is a variable which can takes all possible values in interval for example temperature. Discrete is separate from one another 1,2.3.4,5. Definiton of Statistics : Collecting the data its related with probability and estimate.            

It is confidence which we express in the highly of a thing whose occurrence in a certain situation is uncertain. Probably of occurrence of an event is a real number which lies between zero and one inclusive if the event does not occur its probability is zero and the event to certain to occur its probably of occurrence is one. if in events occur its probability of occurrence is called the probability of success. which is denoted by "p" the probability of non occurrence of an event is called probability of failure which is denoted by "q" where p+q =E+p =1 if there are total "n" equally likely and mutually exclusive possibilities in a random experiment and if an event "A" occurs in "m" number of equally ways than the probably of success of event A is given by p(A)= p= m/n and the probably of failure of event "A" will be p(A') =n-m/n=1-m/n=1-p(A)=1-p. The definition of probability of success of event "A" is calle...
