Statistics is a type of science
mainly concerned with the development as well as the study of various methods.
All these methods are used for the collection, interpretation, and analyzation
of the empirical data. It informs us about the analyzation of things. If you
have ever forecasted the weather, then you have also used statistics there. The
reason behind getting information about the weather are the computers that are
built on the statistical concepts and methods. Statistics comes in two
different and effective types. One is descriptive and the other one is
inferential. Here is the detail of both types.
Descriptive Statistics:
This type is mainly concerned
with the collection as well as the presentation of data. Descriptive type of
statistics is most salient because if we present the data in the raw form then
it would become very difficult to visualize or understand it. It turns the raw
data into simpler form and it becomes more meaningful.
For example, the college has made a test score of mathematics for
the coming students. This prediction of the test scores is made possible due to
the field of statistics.
Types of Descriptive Statistics:
·
Central Tendency
·
Dispersion
Inferential Statistics:
Inferential statistics is the
second type of this field of science. The first type describes the data and the
second type makes predictions according to that data. You can take the data
from samples and can make predictions about that data or about that population.
This type is used when the person
needs to conclude the whole data. Usually, a sample is taken from the
population and hen the conclusion is made according to the trend. But you must
know that this type is only for small populations and not for large
populations.
For example, let’s suppose you are standing in a shopping mall and
are asking fifty people if they like shopping here or not. Then you come to
make the inference that there is almost 60 to 70 percent of people who love to
shop here. This is the inferential statistics.
Types of Inferential Statistics:
·
Analysis of Co-variance
·
Linear Regression Analysis
·
Correlation Analysis
·
Analysis of Variance
·
Statistical Significance
Uses of Statistics:
·
Most people think that there is no use of
statistics in daily life. But they are wrong and are unaware of the use of this
field or branch of science. Here we have mentioned some of the uses of
statistics.
·
One of the main use of this field is testing the
quality. Almost there are hundreds or thousands of companies that produce
different types of products. They have to check the quality but it is
impossible to check the quality of each product. Thus they use the statistical
sample.
·
It is the Statistics that make us aware of the
weather changes. This is done through the computers operated on the statistical
operations.
·
The prediction of diseases is also based on this
field. When doctors predict that there is almost 60 to 70 percent of people who
are suffering from cancer, then this is also due to statistics.
