three levels of data abstraction are: 1. Physical level : how the data is stored physically and where it is stored in database. 2. Logical level : what information or data is stored in the database (like what is the datatype or what is format of data. 3.View level : end users work on view level. if any amendment is made it can be saved by other name. for the database to be usable it must retrieve data efficently.this efficency led designer to use complex data structure in the database

P value is a probability of something happening by chance it denotes the contribution of chance in any hyphothesis testing the value of p lies between 0 to 1 the standered value of p is .05 if any hyphothesis test gives the p value less then this that means that particular x is impacting my project otherwise not.
== == A hypothesis is an idea about how/why something works. To formulate it is to write it down ... in non-ambiguous terms so that other people will understand what you are talking about.
