1.6.8 Statistics and Modern applications:
Recent developments in the fields of computer technology
and information technology have enabled statistics to integrate their
models and thus make statistics a part of decision making
procedures of many organisations. There are so many software
packages available for solving design of experiments, forecasting
simulation problems etc.
SYSTAT, a software package offers mere scientific and
technical graphing options than any other desktop statistics
package. SYSTAT supports all types of scientific and technical
research in various diversified fields as follows
1. Archeology: Evolution of skull dimensions
2. Epidemiology: Tuberculosis
3. Statistics: Theoretical distributions
4. Manufacturing: Quality improvement
7 5. Medical research: Clinical investigations.
6. Geology: Estimation of Uranium reserves from ground
Limitations of statistics:
Statistics with all its wide application in every sphere of
human activity has its own limitations. Some of them are given
Statistics is not suitable to the study of qualitative
phenomenon: Since statistics is basically a science and deals
with a set of numerical data, it is applicable to the study of
only these subjects of enquiry, which can be expressed in
terms of quantitative measurements. As a matter of fact,
qualitative phenomenon like honesty, poverty, beauty,
intelligence etc, cannot be expressed numerically and any
statistical analysis cannot be directly applied on these
qualitative phenomenons. Nevertheless, statistical techniques
may be applied indirectly by first reducing the qualitative
expressions to accurate quantitative terms. For example, the
intelligence of a group of students can be studied on the basis
of their marks in a particular examination.
Statistics does not study individuals: Statistics does not
give any specific importance to the individual items, in fact it

data and do not serve any purpose for...
