What is Business
analytics?
As
defined by Wikipedia, “Business analytics (BA) refers to the skills,
technologies, applications and practices for continuous iterative exploration
and investigation of past business performance to gain insight and drive business
planning.”
In
short, it helps people like us to make informed business decisions and may be
help automate few business processes.
An excellent data analysis could be an asset for the company which they
could leverage it as competitive advantage. A SURE PROMOTION TIP :)
Different BA tools:
1) Many commercial products
available
SAS,
Statistica, Minitab, and others
2) Excel
Widely
available (part of MS Office Suite)
Not
a statistical software – spreadsheet (Finance, math, and statistics
applications)
3) SPSS
Robust
software for sophisticated statistical applications.
SPSS:
What IBM says “With SPSS predictive analytics
software, you can predict with confidence what will happen next so that you can
make smarter decisions, solve problems and improve outcomes”
SPSS
refers to the Statistical Package for the Social Sciences. This package can
perform a number of statistical operations and calculations.
SPSS Statistics was developed by Norman H. Nie, C.Hadlai and Dale Bent and released in 1968. This software is widely used by people working in the field of social sciences. Others users of this software are market researchers, survey companies, Government Agencies, health researchers, educational researchers, and marketing organizations.

Unique Features:
1) User-friendly statistical
software.
2) Store your instructions in the
form of syntax.
3) Important tests such as t-test,
f-test, chi-square test and cross-tabulation can be performed.
4) One can work with missing data
5) Performs discriminant analysis,
analysis of variance, and factor analysis.
Types of Analytics:
1)
Operational
analytics
2)
Customer
Analytics
Operational Analytics:
How can it
help operations?
1) Streamline operational processes to meet
ever-changing customer demands
2) Optimize your production and distribution
channels
3) Overcome short-term stresses or unexpected
marketplace changes
4) More effectively allocate capital and human
resources

Basics about SPSS:
Variables and Cases:
SPSS uses data
organized in rows and columns. The rows are called cases and the columns
variables.
The case contains
information for one unit of analysis like person, animal etc while variables
are the information collected for each case such as age, sex etc.
Variable types
It includes
Dots, Commas, Strings, etc. in the figures.
Width : This helps us to show the number of
characters that can be put in the cell.
Label : It
helps us to provide a detailed description of the variable.
Value : This
is generally used for the items which can be categorised.
Values can be divided into:
1)
Category - for First level analysis.
It is one whose range is countable.
2)
Continuous -for Second level analysis.
It is one which is not categorical.
The continuous variable can be further categorised
into Continuous and Discrete.
There are two views in SPSS :
1) Data
view:
Data View is the view in which we view
and edit the actual data. This data can also be populated by importing excel
files. Each column depicts a variable.
2) Variable
view:
Variable View can be accessed by using
the tab given on the lower left corner. In this view, each variable is
represented as a row, and various properties of the variable are represented as
columns, allowing us to change the properties of existing variables or
establish properties for new variables.
Types of Measures:
1)
Nominal:
It is simply placing data into categories,
without any order or structure.
Examples: A
YES/NO scale is nominal. It has no order
and there is no distance between YES and NO.
2)
Ordinal:
In this
scale values are given based on an order. An ordinal scale only lets you
interpret gross order and not the relative positional distances. Ordinal data
would use non-parametric statistics. These would include
3) Scale:
This scale
tells us the difference between variables.
Types of Analysis :
1)Univariate analysis is the simplest form
of quantitative analysis. It is carried out with the description of a single
variable and its attributes of the applicable unit of analysis.
2)Bivariate analysis or multivariate analysis.
