Which data visualization technique is commonly used to represent the distribution of data values across a range?

  1. Bar Chart

  2. Pie Chart

  3. Histogram

  4. Scatter Plot


Correct Option: C
Explanation:

A histogram is a graphical representation that organizes data points into a series of bins, showing the frequency of occurrence in each bin.

What type of chart is suitable for comparing multiple data sets with different scales?

  1. Line Chart

  2. Area Chart

  3. Stacked Bar Chart

  4. Box Plot


Correct Option: A
Explanation:

A line chart is effective for comparing trends and patterns over time, even when the data sets have different scales.

Which visualization technique is used to display the relationship between two quantitative variables?

  1. Scatter Plot

  2. Heat Map

  3. Treemap

  4. Radar Chart


Correct Option: A
Explanation:

A scatter plot is a two-dimensional plot that shows the relationship between two variables, with each data point representing a pair of values.

What type of chart is commonly used to represent the relative sizes of different categories or groups?

  1. Pie Chart

  2. Donut Chart

  3. Bar Chart

  4. Column Chart


Correct Option: A
Explanation:

A pie chart is a circular chart divided into sectors, with each sector representing a category or group, and the size of each sector proportional to its value.

Which data visualization technique is suitable for displaying hierarchical data?

  1. Treemap

  2. Sunburst Chart

  3. Icicle Plot

  4. Dendrogram


Correct Option: A
Explanation:

A treemap is a hierarchical visualization technique that represents data as nested rectangles, with the size of each rectangle proportional to the value it represents.

What type of chart is used to show the distribution of data values within a specific range?

  1. Box Plot

  2. Violin Plot

  3. Dot Plot

  4. Stem-and-Leaf Plot


Correct Option: A
Explanation:

A box plot is a graphical representation that shows the distribution of data values within a specific range, including the median, quartiles, and outliers.

Which visualization technique is suitable for displaying the relationship between multiple variables?

  1. Scatter Plot Matrix

  2. Parallel Coordinates Plot

  3. Radial Coordinate Plot

  4. Andrews Plot


Correct Option: A
Explanation:

A scatter plot matrix is a collection of scatter plots that shows the relationship between multiple pairs of variables, allowing for the identification of patterns and correlations.

What type of chart is commonly used to represent the change in data over time?

  1. Line Chart

  2. Area Chart

  3. Step Chart

  4. Spline Chart


Correct Option: A
Explanation:

A line chart is a graphical representation that shows the change in data over time, with data points connected by lines.

Which visualization technique is used to display the flow of data between different entities or processes?

  1. Sankey Diagram

  2. Flow Chart

  3. Gantt Chart

  4. Pert Chart


Correct Option: A
Explanation:

A Sankey diagram is a visualization technique that represents the flow of data between different entities or processes, with the width of the arrows proportional to the amount of data flowing.

What type of chart is suitable for displaying the distribution of data values in a categorical variable?

  1. Bar Chart

  2. Pie Chart

  3. Histogram

  4. Frequency Polygon


Correct Option: A
Explanation:

A bar chart is a graphical representation that shows the distribution of data values in a categorical variable, with the height of each bar proportional to the frequency of occurrence.

Which visualization technique is used to represent the relationship between two categorical variables?

  1. Contingency Table

  2. Mosaic Plot

  3. Heat Map

  4. Bubble Chart


Correct Option: A
Explanation:

A contingency table is a two-dimensional table that shows the frequency of occurrence of different combinations of values in two categorical variables.

What type of chart is commonly used to display the distribution of data values in a continuous variable?

  1. Histogram

  2. Frequency Polygon

  3. Dot Plot

  4. Stem-and-Leaf Plot


Correct Option: A
Explanation:

A histogram is a graphical representation that shows the distribution of data values in a continuous variable, with the height of each bar proportional to the frequency of occurrence in each bin.

Which visualization technique is suitable for displaying the relationship between a categorical variable and a continuous variable?

  1. Box Plot

  2. Violin Plot

  3. Scatter Plot

  4. Bar Chart


Correct Option: A
Explanation:

A box plot is a graphical representation that shows the distribution of data values in a continuous variable, grouped by a categorical variable, with the median, quartiles, and outliers displayed for each group.

What type of chart is commonly used to represent the relationship between multiple categorical variables?

  1. Venn Diagram

  2. Euler Diagram

  3. Mosaic Plot

  4. Heat Map


Correct Option: A
Explanation:

A Venn diagram is a graphical representation that shows the relationship between multiple categorical variables, with overlapping areas representing the common elements between the variables.
