Top 10 Computational Statistics Software Tools (Learn How to Use Them)

Alt: = "data analysis"


The need to use software packages in statistical data analysis has increasingly become inevitable. The modern use of the capabilities of these software packages in the real world must be appreciated and embraced by modern data analysts.

Statistical Computing

Computing is the activity of using computers or computer software. It is an essential component of statistical practice and research. Computational tools form the basis for virtually all applied statistics. Investigations in visualization, model assessment and model fitting, all rely on computation. Computation can also be used for statistical inferences.

Statistical computing is basically analysing data using computers. With the widespread access to computers, data processing has become an easier task. Not only has data analysis become easier, we can perform advanced statistical analysis like multivariate analysis with utmost ease. Computers are particularly useful if one has to perform the same task several times., if data set is large etc. Computer can execute the iterative algorithm within a short time and with maximum accuracy.

Tools such as simulation, bootstrapping and Markov chain Monte Carlo are widely used to validate procedures and to provide guidance for both practical and theoretical problems.

Statistical packages for analysis

Numerical Computing: Topics include computer arithmetic, optimisation, numerical linear algebra, random number generation, and simulation.

Computational Inference: Simulation Markov Chain Monte Carlo, bootstrapping, resampling. Problems the can be used to solve: Random number generation, Bayesian methods

Statistical Modeling using software: Basic instruction in using statistical software for fitting models, interpreting output, etc. An introduction to statistical language can be treated here 

Visualization: Techniques for plotting and visualizing data. Appropriate use of colour, basic techniques of information visualization.

Programming Languages: Introduction to programming and the different languages that can be used are Java, Python, Perl, Object-oriented programming, Compilers, procedural languages, scripting languages, Interpreters, distributed computing.

Data Technologies: Markup languages, database and query languages, web services, output delivery systems.

Algorithm Design and Implementation: Learning basic strategies for designing and implementing algorithms. Software design, unit testing documentation user interface design.

Importance of Statistical Computing

1. Technology is rapidly changing the way things are done, and statistical data analysis is not exempted. Manual computation and analysis of statistical data can be labourous, time-consuming and results obtained can be inaccurate and misleading. Statistical computing provides software solutions to statistical practice

2. Data technology: The methods and software used to obtain, manage, manipulate, and store data have changed dramatically. Statistical computing prepare statisticians and data analysts to face the current realities of data analysis and management. Big data technology is used in real time analysis of market trend and performance. It would help one gain knowledge of markup languages like XML, database technologies or web services technologies. Software technologies that are evolving include object-oriented programming, aspect oriented programming, distributed computing and other paradigms and they have important roles to play in the development of statistical packages and hence statistical practice.

3. Computational inference: In many cases, computation and theory are complementary and better results are obtained using both. But, by and large, few statisticians are capable of handling both components. Reliable easy-to-use software implementations can make these tools more accessible and easier.

Alt: = "SPSS logo image

SPSS stands for Statistical Package for Social Science. SPSS, a product of IBM, is a comprehensive software tool for statistical computing and analysis. It has the capability of performing of statistical data analysis task with an easy-to-use graphical user interface. SPSS is best suited for analysis of variance (ANOVA) and analysis of covariance (ANCOVA), and to use it, you need to have good understanding of statistics.

How to Use SPSS for Statistical Data Analysis
SPSS operates using a number of different screens or windows designed to perform different tasks. Before accessing any of these windows you have to either open an existing data file or create a new one. 
We are going to cover how to open and close SPSS existing data file, how to create new data file, and how the functions of different SPSS windows.

SPSS Windows
  1. Data Editor: This window displays the contents of the data file. Here you can create new data files or open and modify existing data files. Data Editor window opens automatically when you start an SPSS session.
  2. Viewer Window: Viewer window displays the outputs or results of analysis in text, pivot table or charts.
Running Analysis on SPSS
When you click on IBM SPSS icon on your PC, it will display SPSS window version you have . It may warn you of compatibility issue. If there is compatibility issue, click on Continue buttion. It will display a screen with dialogue box asking you “what would you like to do?”.  Select “type in data” option and click OK. It will display I window that looks like a spreadsheet. 
The window is what is called Data Editor, here is where you can name your variable and  enter your data.
Before you start to name your variables and enter your set of data, you need to know some rules for naming variables

Rules for Naming Variables
Variables names:
  • Must be unique (that is each variable in a data set must have a different name)
  • Can only have not more than eight characters
  • Cannot include full stop, blank, or special characters like !, *, “ etc
  • Cannot include words used as commands by SPSS (all, he, eg, to, le, it, by, or, gt, and, not, ge, with).
Now let’s proceed

At the Data Editor window, 
  • click the variable view tab and enter the variable
  • Click Data View tab, and enter the data
  • Then click Analyze at the Menu bar
A dialogue box will appear, select the type of analysis you want to run, let’s say Paired sample T-Test.
Select the Variables one by one. This will enable the OK button.
Click OK to display the results
The output will be displayed at the SPSS Viewer Window.

In summary, analysing data using SPSSS is easy and straight forward. All you have to do is:
Get your data into SPSS. You can open a previously saved data file; read a spreadsheet, database, or text data file; or enter your data directly in the Data Editor.
Select a procedure. Select a procedure from the menu to analyse, or to create a chart.
Select the variables for the analysis. The variables in the data file are displayed in a dialog box for the procedure.
Run the procedure and look at the results. The results are displayed in the Viewer.
