Answer :
Final answer:
Regression analysis is crucial for examining connections between variables by determining their nature and significance.
Explanation:
Regression analysis is the tool that data scientists use to examine the connections between variables. This technique helps determine if the relationship between variables is positive or negative and whether a linear or non-linear line better describes the relationship.
Regression analysis is essential to separate the individual relationships of multiple independent variables with a dependent variable and to test the significance and usefulness of these variables in the analysis.
Exploratory Data Analysis (EDA) techniques, such as histograms and correlations, should be used prior to regression analysis to gain preliminary insights and understand patterns in the data.
