It is considered to be very complex and the researcher cannot be certain that other variables influencing the causal relationship are constant especially when the research is dealing with the attitudes of customers in business. Causal models set to be the gold standard amongst all other types of data analysis. The analysis is primarily carried out to see what would happen to another variable if one variable would change.ДЄpplication of causal studies usually requires randomized studies but there are also approaches to concluding causation even and non-randomized studies. Causal determines the cause and effect relationship between the variables. Descriptive statistics, in such cases, may be used to describe the relationship between the pair of variables.Д¬ausal data analysis is also known as explanatory Data Analysis. When the data analysis involves a description of the distribution of more than one variable it is termed as bivariate and multivariate analysis. The analysis which involves the distribution of a single variable is called univariate analysis. There are two methods of statistical descriptive analysis that is univariate and bivariate. Descriptive data analysis has different steps for description and interpretation. Descriptive data analysis is usually applied to the volumes of data such as census data. This is usually the initial kind of data analysis that is performed on the available data set. It describes the main features of the collection of data, quantitatively. This method requires the least amount of effort amongst all other methods of data analysis. Few of them are Data Applied, Ggobi, JMP, KNIME, Python etc.

Software and machine-aided have become very common in EDA analysis. Exploratory data analysis can be applied to study census along with convenience sample data set. The data provides correlation which does not imply causation. The drawback of exploratory analysis is that it cannot be used for generalizing or predicting precisely about the upcoming events. Graphical techniques of representation are used primarily in exploratory data analysis and most used graphical techniques are a histogram, Pareto chart, stem and leaf plot, scatter plot, box plot, etc. Exploratory data analysis was promoted by John Tukey and was defined in 1961. The approach to analyzing data sets with visual methods is the commonly used technique for EDA. The answers provided by exploratory analysis are not definitive in nature but they provide little insight into what is coming. They are specifically used to discover and for new connections and for defining future studies or answering the questions pertaining to future studies. It is one of the types of analysis in research which is used to analyze data and established relationships which were previously unknown. A) Univariate descriptive data analysis.
