10 Best Free and Open Source Statistical Analysis Software

“We are surrounded by data, but starved for insights.” -Jay Baer  (American Author). Having Data does matter, but what you do with it matters more. Marketing Managers around the world have to take a lot of decisions every day based on the data available to them. Often marketers find themselves immersed in the flood of enormous data but no exact conclusion. Here, statistical analysis comes to their rescue. Statistical analysis makes it easy for them by deriving conclusive figures that can help marketers to take important decisions. That is why statistics is important for making business decisions.

However, collecting data and analyzing it for deriving statistical conclusions are not easy tasks. Fortunately, technology is there to provide relief to present-day businesses. There is software that can analyze a huge amount of data for the final results.

What is Statistical Analysis Software?

Statistical Analysis software is capable of integrating, analyzing, and interpreting a massive amount of data in a statistical framework. It can apply multiple statistical tests and categorize data for finding unique readings. It can compare two or more data types to find statistical similarities or variations. Statistical software is mostly used in quantitative research for data analysis.

Need for Statistical Analysis Software:

Businesses are constantly in search of statistics related to their fields. They need something concrete to rely on while taking informed business decisions. The scale at which businesses work today is quite large, and the data available is huge. It is not possible for managers or statisticians to analyze the data manually. A lot of data inaccuracies can creep in due to human errors.

Statistical software has features to combat the common statistical errors related to categorical data analysis. With categorical data, marketers may not find the relevant information required to make decisions. A bag manufacturing company classifies its products into various categories.-Hand Bags, backpacks, trolley bags, ladies purse, wallet, etc. This is an example of categorizing (discrete characteristics). The problem with categorical data is that there is no mathematical meaning to it. If the company checks the revenue bills and finds that out of all its products, 6 million trolley bags were returned by customers in two years out of the 30 million sold, it means, the company is using the continuous data (variables of measurement) to derive at this conclusion. Continuous data can be analyzed for statistical inferences. The statistical inference is that 20% of goods sold were returned.

Take another example. A production manager decides to divide the quantity of Ice-cream production month-wise equally. He has categorized the production quantity from January to December equally. It is a statistical fallacy. He misses the point that the sales department will require more ice-cream in the months of May-July as it is a common fact that ice-cream sells more in Summer. It is the limitation of the categorical data, and that is why continuous data is required to give a clear view of the situation.

That is why continuous data is more important than the categorical one. Statistical analysis software has the inbuilt features to identify the type of data it is processing, and based on it; the software applies the required test. For categorical data, the software uses descriptive statistics, and for continuous data, it uses linear regression, time-series, and many more. Similarly, it has features to get rid of inaccuracies deriving from improper use of cluster algorithms and segmentation.

To avoid data inaccuracies and to save time, managers rely on applications and software suites that are capable of performing statistical analysis. These software help managers save a lot of time and also make the process easy for them. Applying statistics to data requires marketers to conduct a lot of tests on the data for the final results. The applying, processing, and interpreting part of these tests requires a statistical analysis software.

Statistics resolves a lot of issues in marketing. Statistics clears the vision and gives complete control of the situation to the marketers.

 Statistics:

  1. Provides a clear understanding of the situation
  2. Produces concrete data to act upon
  3. Increases accuracy in decision making
  4. Improves the quality of decisions
  5. Gives insights for strategic decision making

Types of Statistical Tests:

Statistical software should be able to conduct the essential statistical tests shown in the below figure:

Features of a Statistical Software:

Statistics itself has developed a lot in recent years. Prominent statisticians around the world have introduced various new tests and analysis types, thereby adding new aspects and dimensions to the field of statistical analysis. Statistics involves multiple tests, correlations, variable-analysis, and hypothesis testing, that makes it a complicated process.

A statistical analysis software has the following features to make complicated statistical functions easy.

Conclusion:

When we are in an unknown territory, we rely on maps to guide us because it provides us the guidance that we need to trail the unknown path. Maps are not just random lines drawn on a piece of paper, but they are charted after a thoroughly calculated mapping process. It makes them reliable and valuable. Similarly, companies venturing out in unexplored trajectories need filtered data to guide them. Statistics does this filtering of data for finding out the value statements. Statistics gets rid of the massive data and brings valuable facts on the table.

Everyone today is a data-driven. For running mainstream businesses, relying just on experience, instincts, or goodwill is no longer sufficient.

When businesses are uncertain of the qualitative data that they possess, then quantitative analysis with the help of statistics can really provide them a concrete piece of information to make decisions.

The beauty of statistics is that companies need not talk to each customer to find out their views about their products and services. Sampling a representative group and applying statistical tests would itself result in extremely helpful insights about the whole group. Also, with statistics in hand, it becomes easy for managers to convince their board, stakeholders, or sub-ordinates of any change they might want to bring. 

With the assistance of statistical software, managers can ensure consistent growth, customer satisfaction, strong points in their businesses, and the weaknesses that are hampering growth.

Marketers, businesses, researchers, and concerned entity can use the statistical analysis software discussed in the article for their statistical requirements.
