What is the Use of Minitab in Data Analysis?

Data analysis is the use of tools and techniques to transform raw data into knowledge that can be used for decision-making and other purposes. The data analysis process typically comprises theory formulation, hypothesis testing, setting up of a research design, data collection, analysis, and interpretation of findings.

As of 2024, the latest version of Minitab is version 22.1.0. It is useful because it provides a user interface that makes data analysis simpler for all levels of users. This is attributed to the presence of pull-down menus and dialog boxes that give you easy prompts for every step of the analysis process. It also enables you to spend more time exploring your data and has an importing/exporting capability that allows you to easily transfer data from various software, making data analysis easier.

Statistical Analysis Using Minitab in Research

Minitab is a statistical and data analysis software tool that is used by companies and organizations globally for quality improvement and cost reduction. It provides users with tools to perform statistical analysis, including hypothesis testing, regression, factor, cluster and capability analysis, and ANOVA. In this section, we discuss the analysis methods and how to conduct data analysis.

Statistical Analysis Methods in Minitab

(1). Correlation analysis

A correlation analysis is used to quantify the strength of association between two variables. To perform a correlation analysis in Minitab, 1.) Select Stat> Basic Statistics> Correlation 2.) Select your variables from the list and click the Select button 3.) Click OK.

(2). T-test

The t-test is an analysis procedure that tests the hypothesis of two population means. MINITAB can conduct both independent and dependent T-tests.

(3). Regression analysis

To perform a regression analysis in Minitab, 1.) Select Stat> Regression> Regression… 2.) Choose the response (dependent) variable 3.) Choose the predictor (independent) variable. Click OK. The output consisting of the slope, intercept, and squared multiple R is displayed.

(4). Factor Analysis

Factor analysis evaluates the structure of your data by identifying any patterns and correlations between variables. To perform a factor analysis in Minitab, click on Stat> Multivariate> Factor Analysis.

(5). Cluster Analysis

Cluster analysis uses data to arrange scattered objects into groups. This analysis method is used to establish that a set of clusters is similar to each other more than other objects in another cluster. Cluster analysis in Minitab uses a hierarchical method that begins with single clusters which then merge to form larger ones.

(6). Capability Analysis

Capability analysis is a method that is used to evaluate whether a system is statistically able to meet a set of requirements. Capability analysis in Minitab examines continuous process data using two methods which are before/after capability comparison and capability analysis. The former evaluates whether there was an improvement before and after applying a process, and the latter evaluates capability based on a single variable.

How to Do Data Analysis in Minitab

Step 1: Create a Data File

The first step is creating a data file that consists of a large number of rows and a maximum of 80 columns. Data for the same variable are placed in the same column and a row contains data of the same object of analysis.

Step 2: Enter Data Using a Prompt System to a Worksheet

Data is entered with the prompt system either row by row using the read command or column by column using the set command. The columns, which are the values of a variable, are labeled c followed by a number, for example, c1 and c2.

Step 3: Save the Data on a Desktop

After entering the data in a worksheet, you can now save it on the desktop. To save it: 1.) From the File menu, select Save Current Worksheet As… 2.) Click on the icon on the desktop  3.) Type an appropriate file name.

Step 4: Conduct Analysis

You can now conduct data analysis depending on your data set. Data analysis can be Minitab attribute agreement analysis, cluster analysis, capability analysis, analysis of variance, or regression analysis.

Step 5: Save the Data Output

Once satisfied with the analysis, you can now save the output and obtain a hard copy. To save the output file, click on File, then Save Session Window As… on your desktop.
