Which data visualization technique is most suitable for displaying the distribution of data?

  1. Bar chart

  2. Pie chart

  3. Histogram

  4. Scatter plot


Correct Option: C
Explanation:

A histogram is a graphical representation of the distribution of data. It is a bar chart with the height of each bar representing the frequency of occurrence of a particular value or range of values.

What is the purpose of a scatter plot?

  1. To display the relationship between two variables

  2. To compare multiple datasets

  3. To show the distribution of data

  4. To identify outliers


Correct Option: A
Explanation:

A scatter plot is a graphical representation of the relationship between two variables. Each point on the plot represents a pair of values, one for each variable. The pattern of the points can reveal the nature of the relationship between the variables.

Which chart type is best suited for visualizing time-series data?

  1. Line chart

  2. Bar chart

  3. Pie chart

  4. Scatter plot


Correct Option: A
Explanation:

A line chart is a graphical representation of data over time. It is a series of points connected by lines, with the points representing the values of the data at specific time intervals.

What is the difference between a bar chart and a histogram?

  1. Bar charts display categorical data while histograms display quantitative data

  2. Bar charts display individual data points while histograms display the distribution of data

  3. Bar charts are always vertical while histograms can be either vertical or horizontal

  4. Bar charts are more commonly used for comparing data while histograms are more commonly used for displaying the distribution of data


Correct Option: A
Explanation:

Bar charts are used to display categorical data, while histograms are used to display quantitative data. Bar charts show the frequency of occurrence of each category, while histograms show the distribution of data values.

What is the purpose of a pie chart?

  1. To compare multiple datasets

  2. To show the distribution of data

  3. To display the relationship between two variables

  4. To identify outliers


Correct Option: B
Explanation:

A pie chart is a graphical representation of the distribution of data. It is a circle divided into sectors, with the size of each sector representing the proportion of the total data that belongs to that category.

Which data visualization technique is most suitable for displaying the relationship between three or more variables?

  1. Scatter plot

  2. Bar chart

  3. Pie chart

  4. 3D scatter plot


Correct Option: D
Explanation:

A 3D scatter plot is a graphical representation of the relationship between three or more variables. Each point on the plot represents a set of values, one for each variable. The pattern of the points can reveal the nature of the relationships between the variables.

What is the purpose of a box plot?

  1. To display the distribution of data

  2. To compare multiple datasets

  3. To show the relationship between two variables

  4. To identify outliers


Correct Option:
Explanation:

A box plot is a graphical representation of the distribution of data. It shows the median, quartiles, and outliers of the data. Box plots are useful for identifying outliers and comparing the distributions of different datasets.

Which data visualization technique is most suitable for displaying the trend of data over time?

  1. Line chart

  2. Bar chart

  3. Pie chart

  4. Scatter plot


Correct Option: A
Explanation:

A line chart is a graphical representation of data over time. It is a series of points connected by lines, with the points representing the values of the data at specific time intervals. Line charts are useful for showing the trend of data over time.

What is the purpose of a heat map?

  1. To display the distribution of data

  2. To compare multiple datasets

  3. To show the relationship between two variables

  4. To identify clusters and patterns in data


Correct Option: D
Explanation:

A heat map is a graphical representation of data where the individual values are represented by colors. Heat maps are useful for identifying clusters and patterns in data.

Which data visualization technique is most suitable for displaying the relationship between two categorical variables?

  1. Scatter plot

  2. Bar chart

  3. Pie chart

  4. Contingency table


Correct Option: D
Explanation:

A contingency table is a tabular representation of the relationship between two categorical variables. It shows the frequency of occurrence of each combination of categories.

What is the purpose of a treemap?

  1. To display the distribution of data

  2. To compare multiple datasets

  3. To show the relationship between two variables

  4. To identify clusters and patterns in data


Correct Option: D
Explanation:

A treemap is a graphical representation of data where the individual values are represented by nested rectangles. Treemaps are useful for identifying clusters and patterns in data.

Which data visualization technique is most suitable for displaying the relationship between a categorical variable and a quantitative variable?

  1. Scatter plot

  2. Bar chart

  3. Pie chart

  4. Box plot


Correct Option: D
Explanation:

A box plot is a graphical representation of the distribution of data for each category of a categorical variable. It shows the median, quartiles, and outliers of the data for each category. Box plots are useful for comparing the distributions of data for different categories of a categorical variable.

What is the purpose of a bubble chart?

  1. To display the distribution of data

  2. To compare multiple datasets

  3. To show the relationship between three variables

  4. To identify clusters and patterns in data


Correct Option: C
Explanation:

A bubble chart is a graphical representation of data where the individual values are represented by bubbles. The size of each bubble represents the value of a third variable. Bubble charts are useful for showing the relationship between three variables.

Which data visualization technique is most suitable for displaying the relationship between two quantitative variables?

  1. Scatter plot

  2. Bar chart

  3. Pie chart

  4. Line chart


Correct Option: A
Explanation:

A scatter plot is a graphical representation of the relationship between two quantitative variables. Each point on the plot represents a pair of values, one for each variable. The pattern of the points can reveal the nature of the relationship between the variables.

What is the purpose of a radar chart?

  1. To display the distribution of data

  2. To compare multiple datasets

  3. To show the relationship between multiple variables

  4. To identify clusters and patterns in data


Correct Option: C
Explanation:

A radar chart is a graphical representation of the relationship between multiple variables. Each variable is represented by a spoke on the chart, and the value of each variable is represented by the length of the spoke. Radar charts are useful for comparing the values of multiple variables for different objects.
