the backbone of many subjects .Statistics is mainly concerned with the
collection of data and then interpreting the data in a certain manner .Data
interpretation is an integral part of any analysis and mostly the job of
statisticians is considered to be very useful in this regard. Statistics is
basically based on three measures of central tendency namely mean, median and
mode which are used to compare various data sets and arrive at very important
results which could be further used in policy analysis. Sometimes studying the entire sample might
not be possible because of its huge size and hence then it becomes imperative
to draw out a small sample out of the existing population and to arrive at
particular results and also to lower the extraordinary high cost that needs to
be occurred while collecting a huge data set. Data collection is of two types descriptive and
inferential .Descriptive data analysis consists of collecting data and doing a
statistical analysis mainly in the form of graphs and all whereas inferential
analysis consists of drawing certain theoretical inferences out of the data in
the form of hypothesis testing or regression analysis .One of the other basic
principle of statistical theory probability analysis is also used in a lot of
models for statistical inference as well as analysis. Hypothetical analysis is
also a very powerful tool that is used to test whether correlation exists
between two particular variables or by using certain tests such as the Z-
test,F test etc. Regression analysis has become all the more advanced using
softwares such as STATA which can be used to analyze huge volumes of data and
to check whether a particular variable is significant while explaining a certain model or not © 2014 myassignmenthelpAuthor's Note
