Question

Name one type of chart/graph suitable for analysing a single variable (univariate analysis) and one type for analyzing the relationship between two variables (bivariate analysis).

Hint:

Use histograms for single-variable trends and scatter plots for comparing two variables visually.

Answer 1

Univariate Analysis: A histogram is ideal for analyzing the distribution of a single numerical variable.
It shows the frequency of data within intervals, helping to identify patterns like skewness or outliers.
Bivariate Analysis: A scatter plot is used to study the relationship between two numeric variables.
It shows how one variable changes in relation to another, making it easy to detect correlations or trends.
These charts help researchers and analysts interpret data effectively and make data-driven decisions.
