Statistical software tutorial




















Statistical software are specialized computer programs which help you to collect, organize, analyze, interpret and statistically design data. There are two main statistical techniques which help in statistical data analysis: descriptive statistics and inferential statistics. Descriptive statistics organize data from a sample using indexes. Inferential statistics draw a conclusion from data that is a random variant. Statistics are crucial for organizations.

They provide factual data which is critical in detecting trends in the marketplace so that businesses can compare their performance against their competitors. This article is about the best statistical software available in the market and online.

It will help cut down your manual processes and introduce smarter ways of handling your company data and information. Multi-Platform Support. By the end of this article you will know which software is best for your business. Check all the software in detail according to your needs and choose wisely.

This is a very easy-to-use and affordable statistical software available online. Three easy steps are required to finish the statistical analysis within a single dialog box. Since it provides step by step analysis it is handy for students and young scholars. The cost increases with additional features. Visit MaxStat Now.

In WizardMac, no typing or programming is required for data analysis. Any professional can start their survey with the help of WizardMac.

The predictive models help to make the business choices very easy. A free trial version of WizardMac is available. The more features available in a package, the higher the price. Visit WizardMac Now. AcaStat is one of the best statistical analysis tools available online and it analyses data using very simple statistical tools. This program can either be copied and pasted into the R command line, line by line or as an entire program.

You may also source this program from where it is saved on your computer as shown below. It is often useful to set a working directory so that file names without a pathname will refer to files in that directory on your system.

The command getwd will print your working directory to your screen. One nice feature of the step-by-step command lines in R is that you may scroll through previous commands using the Up and Down arrow keys.

Here are a couple of other handy commands that you can use in R:. Depending on the course, datasets are either presented within the context of the lesson or within a datasets folder. Common file extensions for data files include. You must download the data from your course website. Canvas provides instructions on how to save a file for Windows users or Mac users.

A Save dialog box will be displayed and allow you to save the data file to the location you choose on your computer. There are a number of ways to read data into your R session. Two popular commands used in the examples presented here are read. The "Graphics Fundamentals" tutorial concentrates on the most fundamental and most widely used of the Mathematica plotting capabilities, the use of the Plot function to generate two dimensional graphics.

We also recommend dowloading tut. The tutorial in it will cover the basic aspects of Mathematica such as statement syntax, mathematical operations and graphics, as well as some system interactions such as saving and printing your files. It is designed primarily for structural equation modeling and similar analyses e. HLM Hierarchical Linear Models are used for analyzing data in a clustered or "nested" structure, in which lower-level units of analysis are nested within higher-level units of analysis.

For example, students are nested within classrooms, which are nested within schools. While experimenters are often not interested in the effects of a particular classroom or school when they are examining the effects of a classroom intervention, these units potentially have an effect on the outcome of the study that should be accounted for in a statistical model.

The program can be used to analyze a variety of questions using either categorical or continuous dependent variables. Also, they can be used to perform regression analysis and some multilevel or hierarchical linear modeling HLMs. Many of the statistical methods are also now available for the analysis of complex sampling designs.

M plus is primarily designed for conducting exploratory factor analysis, confirmatory factor analysis, and structural equation modeling. The program can also handle multiple group analysis and multilevel SEM. Over the years SAS has developed a reputation of being a powerful and full-featured package for general statistical analysis. In particular, the current version of SAS has a substantially enhanced windows-driven interface which allows you to point and click your way through many tasks that previously required knowledge of SAS programming syntax.

SPSS is extremely popular in the social sciences and is known for its user-friendly menus for running a large variety of advanced statistical tests and procedures. In the "Getting Started" tutorial, we introduce readers to the SPSS for Windows environment and discuss how to create or import a dataset, transform variables, manipulate data, and perform descriptive statistics. The next three tutorials focus on running descriptive and inferential statistics, graphically displaying data and exporting tables into other applications, and data manipulation and management.
