Statistical tools are necessary regarding the analysis of the data collected either for some research or if they are the students of statistics. In both, the cases applying the tools is quite difficult as lengthy processes and calculations are required to be applied before the final output obtained. For easing out the process of the student’s various companies have launched software and tools that used for making the calculation process quick and easy. Apart from easing the process of calculation these tools help the students to zero down the error rate and produce accurate results based on the input provided. Here is the list of few most popular software that would change the opinion of the students about the tough calculations involved in statistics.
Statistical Package for Social Sciences (SPSS) is a software that has been launched by the IBM. This data is useful for the students as it allows them to do data entry and create various tables along with graphs to analyse the data thoroughly. This software is much applicable to the social sciences and buzz world, where the data to be managed, is move and calculations are lengthy. It can be easily installed on a computer running any version of Windows as well as for desktops having an open source operating system. The data is entered through the worksheet, and the various options are present to work on the data. For example, under the data option, you will have a list that includes multiple formats of searching, sorting and arranging it. Also, there is a choice of graphs that allows the user to plot graphs of different types depending upon the requirement of data. It is a Graphical User Interface (GUI), and no written commands are required. The only selection has to be made.
Stata is statistical analysis software developed in 1982 by StataCorp LP. Apart from data analysis, the software embeds a broad range of services like data management, plotting graphs, provides exact case-control statistics and various tests along with their predictions. This a list of the main features of Stata. There is much more to the software which in turn allows the quick processing of the data. Just one click and the data entered in the worksheet gets converted into a graph or a chart depending upon the requirement of the calculation. The software is available for almost all versions of various operating systems and thus is considered to be flexible. Varying versions of the software is available for ever-changing needs of the users. For example, some might use Stata/SE for large data sets while some of the users might be interested in using it for multiprocessor computers called Stata/MP. Thus, students can buy the version depending on their needs and data analysis.
Microsoft Excel is a program that contains spreadsheets allowing the users to enter numerical values and formulae for calculations. This software is marked as highly useful for statistical calculations. It includes a list of methods and thus allows the users to just select the row and formula. There might be some methods that are no included in the list, but they can be appended manually by the user. Here is an additional feature which makes it all the more suitable for the users. It contains a list of different graphs that can be included in the calculation process making it easy for the user to display the results. In addition to the basic designs, there are a lot of new types of graphs included in the list. The pages are called spreadsheets and are in a tabular format. The users can work simultaneously on different sheets, and the collection of sheets is known as a work book. The users have to install the entire package of Microsoft Office for Excel to work properly. It is mainly available for Windows users.
Here is one of the leading statistical software which was established in the year 1972. It is one of the most widely used software because all the great companies and colleges are using it. As per a survey, almost 90% of the total business firms and approximately 4000 colleges and universities are using this software for analysing their statistical data. This software is the highest version of the Minitab launched initially. This software is useful for even those who do not have any experience of the statistics. The software includes two main analyses namely, Design of Experiments and Multiple Regression. Apart from these new features, the users get access to the regular analysis methods like capability analysis hypothesis chart and control charts. Minitab 17 has gained acceptance around the globe, and for the same reason, the company has launched the product in various regional languages like French, English, German, Spanish and Chinese. The prompt customer support system is the backbone of the success story of Minitab 17.
R is a termed as an open source programming language along with being software. It is specially designed for the statistical analysis of data along with providing graphical interpretations that are supported by R foundations only. It was developed with the motive of providing free availability of statistical analysis tool. It is an open source language and software that means it can be used to develop statistical tools along with providing them itself. It is mainly a command based software and less of GUI that makes it a bit tough to use. Thus, it is less popular these days as long codes are required to execute the statistical analysis and consumes time. However, for those who have a passion for programming in statistics, R acts as a blessing in disguise. It is possible for them to play with numbers and figures.
Thus, all these tools have their unique features in form to produce the best results for any of the statistical data entered by the user. Some are command based while others have GUI, but the main motto is to get unified and accurate result in any situation.
