Introduction
Welcome to the session on ‘Bivariate and Multivariate Analysis’.
So far, you have learnt how to preprocess and clean data, and then you performed a univariate analysis on the bank marketing dataset. A univariate analysis includes the analysis of individual categorical variables like job, education, response, marital status, etc. It also explains the concept of outliers, and mean, median or mode of numerical variables such as salary, balance and age.
Now, consider the following graph, which plots the ‘Response’ and the ‘Salary’ columns from the bank marketing dataset. You have already plotted this graph in the previous segments. Although the median , maximum and minimum values are the same, customers with a higher salary range show interest in opening term deposit accounts with the bank. This is nothing but a bivariate analysis, that is, the analysis of two variables/columns in the data set.
In this session
In this session, you will learn how to analyse two or more variables at a time. You will also observe and draw better inferences on the types of customers that are showing interest in opening term deposit accounts with the bank. This will give you better insights and understanding of how to conduct effective marketing campaigns in the future.
You have already learnt about the types of variables, that is, categorical and numeric variables, in the previous sessions. This session has been divided into the following topics based on the different types of variables
- Analysis Between Two Numeric Variables
- Analysis Between Numeric and Categorical Variables
- Correlation Versus Causation
- Analysis Between Two Categorical Variables
- Multivariate Analysis
