Cross-tabulation to see the association between the two categorical variable.Histogram and Density Plot to visually see the skewness.Standard Deviation, Range, Interquartile Range, Percentile Distribution to measure the scatter/spread in the data.Mean, Median to find the central measure.Pie Chart to show the parts of the whole.Frequency Table to show absolute counts and proportions.Check the Mode, the most occurring category.Then proceed to check the association/relation between two or more variables (Bivariate and Multivariate Analysis). The way descriptive analysis is done is to start simple analyze one variable at a time (Univariate Analysis). The first five records of the MBA Student Data Set is given below: You can use Python/R programming tool for performing the analysis. You can download the datafile Mba_Students_Data.csv from our website ( Download Link). The dataset has 16 variables and 200 observations. As part of their evaluation process, the company has asked you to perform Descriptive Analysis using Tabular & Graphical Methods on a dataset containing 200 MBA student records. The most frequently used visual representation of data are Bar Plot, Histogram, Pareto Chart, Box Plot, Pie Chart, Line Plot, and Scatter Plot.ĭescriptive Analysis of MBA Students DataĪssume you are appearing for a Data Science job interview. The visuals make the data intuitive and self-understandable. Graphical Methods are a visual way of presenting data using charts and graphs. The most frequently used tabular format for data summarization is Frequency table and Cross-tabulation It is a systematic organization of information in grid row and columnar structure. Tabular Methods are used to summarize the data in table form. It is also important that you have a fair understanding of “ Types of Variables” before proceeding with this section. In this blog, we will now focus on the Tabular and Graphical Methods. Moreover, in our Exploratory Data Analysis blog, we mentioned that Tabular & Graphical Methods are important tools to perform EDA. We have already covered the Numerical Methods in earlier blogs. Descriptive Statistics is performed using tabular, graphical, and numerical methods.
