Types of Statistical Graphs

What type of graph is best used to show the comparison of different categories or groups?

• Scatter plot

• Bar graph

• Pie chart

• Line graph

Which type of graph is used to display data that changes over time?

• Bar graph

• Line graph

• Pie chart

• Scatter plot

What type of graph is circular in shape and shows the proportion of each part to the whole?

• Line graph

• Scatter plot

• Pie chart

• Bar chart

Which type of graph is used to represent the frequency distribution of continuous data?

• Pie chart

• Bar graph

• Line graph

• Histogram

In a bar graph, what does the length of each bar represent?

• The color of the bars

• The font size of the graph

• The value of the data

• The number of categories

What is the main purpose of a line graph?

• To compare different categories

• To display geographical data

• To represent categorical data

• To show trends and changes over time.

What is the main advantage of using a pie chart?

• Easy comparison of data points

• Visual representation of proportions

• Detailed data analysis

• Ability to show trends over time

How are histograms different from bar graphs?

• Histograms represent the distribution of continuous data, while bar graphs compare different categories of data.

• Histograms are used for qualitative data, while bar graphs are used for quantitative data.

• Histograms show data over time, while bar graphs show data at a single point.

• Histograms have horizontal bars, while bar graphs have vertical bars.

When should you use a line graph instead of a bar graph?

• When you want to compare individual data points

• When you want to show trends over a continuous period of time or data points.

• When you want to show percentages

• When you want to display categorical data

What is the key feature of a pie chart that makes it easy to understand the data?

• Visually represents proportions of a whole

• Uses 3D effects to enhance data visualization

• Displays data in a linear format

• Includes detailed annotations for each data point
