2. STATISTICAL SOFTWARE
Specialized computer programs that help you collect, organize and
analyze your data using statistical methods.
Advantages of using statistical software include being free from
manual tasks , saving time , dealing with large amount of data and
obtaining valid and reliable results .
Types : SPSS, STATA , SAS

4. APPLICATIONS :
IN MEDICAL RESEARCH : Due to advancement in technology, statistical tools are
being used in medical research for greater efficiency and accuracy . These tools are
easy to use and they handle end to end processes of collecting, organising ,
analysis and interpreting data.
Use of statistical tools allows clinical researches to draw reasonable and accurate
inferences from collected information and to make sound decisions in presence of
uncertanity. This can prevent numerous errors in medical research .
IN EDUCATION : STATA: because of its rising popularity , department of economics
at various universities have chosen it as primary stastical software used among
core courses. It engages with fundamental statistical analysis, executes advanced
5. Cont.
econometric procedures and creates visually stunning graphs and tables.
SPSS : These are used in social science related research projects to analyse
enormous data .That can be used in surveys, market research, data mining etc.
With help of this , researchers can easily identify particular products demand in
market .
STATISTICAL SOFTWARE AND MATHEMATICS :
The potential of learning from computers has shifted to learning with computers
using these softwares. Students learning the characteristics of algebraic function
through interacting with graphic software package by inputting test equations and
observing the fit with correct one is one such example. Students are able to
participate in learning processes by using design feature embeded within
application .
6. IN BUISNESS : using these software tools , we can analyse the business as a
whole . We can integrate all the data sets from different parts of business and
then get insights that can help us to make decisions that are most appropriate
for specific situation. Without software , business would be forced to do
everything manually using a lot of guesswork. With help of software data sets
from across the business can be analyzed using different approaches . This
will help company take preventive measures against unforeseen events in
future .
IN HEALTHCARE : IBM SPSS helps healthcare organizations worldwide
support medical research , improve disease management , monitor the quality
of patient care, improve operational efficiency. It lets you easily investigate
relationship between variables, such as patient treatments and dose responses
in clinical trials .
7. In Economic data : Statistical methods are to collect and analyse the data and test
hypotheses. The relationship between supply and demand Is studied by statistical
methods using softwares , imports and exports , inflation rates , and per capita
income are problems which requires statistical methods .
IN FOOD SCIENCE : Quantification of toxins in food
and nutrient content determination rely on dependable
methods of chemical analysis. Statistical techniques play a
part in monitoring and reporting of such results. This gives
confidence that results are valid and consumers benefit in
the knowledge that certain foods are safe and that diet
regimes can be planned with surety
8. The advantages of using these programs in food research are ; graphs with a
high definition can be generated in seconds , simulations of result can also
be performed using a small amount of time .
IN PHARMACEUTICAL INDUSTRY ; pharmaceutical statistics is application of
statistics to matter concerning the pharmaceutical industry like analysis of drug
trial or design of experiment .
Evaluates the activity of drug , eg. effect of caffeine on attention .
To explore whether the change is produce by drug are due to action of drug or by
chance .
To compare the action of one or two different drug or different dosage of same drug
are studied using statistical method .
9. OTHER APPLICATIONS :
DEMOGRAPHIC STUDIES ; Age , gender , height , weight , BMI
DESIGN and analysis of clinical trials in medicine .
Analysis of genomic data . Related to often disease and disease control .
ASTRONOMY ; Measurement of sizes , masses, and density of heavenly bodies by
means of observations .
ACCOUNTING AND AUDITING , PUBLIC HEALTH , ETC
