What is the most common type of chart for showing the distribution of a numerical variable? Column chart Histogram Two-way table Pie chart

The most common type of chart for showing the distribution of a numerical variable is a **Histogram**. ### Explanation: - **Histogram**: This chart is specifically designed to display the frequency distribution of numerical data. It groups data into bins or intervals and shows how many data points fall into each bin, making it easy to visualize the distribution of the variable. - **Column Chart**: While it can show data distribution, it is more commonly used for categorical data rather than numerical distributions. - **Two-way Table**: This is used to display the relationship between two categorical variables, not for numerical distributions. - **Pie Chart**: This chart is used to show proportions of a whole, typically for categorical data, and is not suitable for displaying the distribution of numerical variables. Thus, the correct answer is **Histogram**.
