Which of the following is an example of categorical data?

• The weight of individuals measured in kilograms

• The brands of cars in a dealership (Toyota, Honda, Ford)

• The prices of houses in a city

• The number of children in a household

What is the key difference between univariate and multivariate visualization?

• Univariate visualization analyzes patterns, while multivariate ignores patterns

• Univariate involves one variable, multivariate involves two or more variables

• Univariate looks for outliers, multivariate looks for missing data

• Univariate focuses on numerical data, multivariate focuses on categorical data

Which type of plot would be most appropriate for visualizing the distribution of a single numerical variable?

• Box Plot

• Scatter Plot

• Histogram

• Bar Chart

A box plot is typically used to:

• Show the relationship between two numerical variables

• Visualize the distribution and spread of a numerical variable, including outliers

• Compare categories in a dataset

• Display the frequency of different categorical values

In a scatter plot comparing house prices and square footage, a point located far from the general trend may indicate:

• A missing data point

• A multivariate relationship

• An outlier

• A categorical pattern

What is the main goal of identifying patterns and outliers in data visualization?

• To automatically predict future trends

• To filter out unnecessary data

• To understand the distribution and relationships in the data

• To avoid using complex statistical techniques

If you wanted to compare the distribution of test scores across different schools, which visualization would be best?

• Scatter Plot

• Histogram

• Box Plot

• Pie Chart

Which of the following best describes a histogram?

• It shows how two numerical variables are related

• It displays the distribution of a categorical variable

• It shows the distribution of a numerical variable using bars

• It compares proportions between different categories

When should a multivariate visualization be used?

• When analyzing a single numerical variable

• When exploring relationships between two or more variables

• When you want to identify missing data

• When analyzing a categorical variable

In the scenario where you are exploring e-commerce data, which plot would best help you identify the relationship between customer age and the amount spent?

• Box Plot

• Histogram

• Scatter Plot

• Pie Chart
