Graphing

What is a line graph?

• A type of chart that displays information as a series of data points connected by straight line segments, used to show trends over time.

• A chart that uses bars to represent data values for different categories.

• A diagram that represents data using circles to show proportions.

• A visual representation of data using dots and lines to indicate relationships.

How can you find the total number of participants in a survey from a bar graph?

• By counting the number of bars in the graph.

• By adding the values represented by each bar.

• By looking at the highest bar only.

• By estimating based on the graph's height.

How do you interpret a graph with multiple lines?

• A graph with multiple lines allows for comparison between different datasets.

• A graph with multiple lines shows only the highest value among the datasets.

• A graph with multiple lines is used to display a single dataset over time.

• A graph with multiple lines is not useful for analysis.

What is a data point in a graph?

• A data point is a single value that represents a specific observation in a graph, typically plotted as a dot or marker.

• A data point is the average of all values in a graph.

• A data point is a line connecting two points on a graph.

• A data point is a label used to identify a graph.

What does it mean when a line graph is increasing?

• It indicates that as one variable increases, the other variable also increases.

• It shows that one variable decreases while the other increases.

• It means that both variables remain constant over time.

• It suggests that there is no relationship between the two variables.

What is a circle graph (pie chart)?

• A circular statistical graphic divided into slices to illustrate numerical proportions.

• A type of graph that only displays linear data.

• A graph that shows data in a three-dimensional format.

• A bar graph that represents categorical data.

How do you determine the least popular option in a circle graph?

• Look for the slice with the largest angle or area, which represents the highest percentage of the total.

• Identify the slice with the smallest angle or area, which represents the lowest percentage of the total.

• Choose the option that is furthest from the center of the circle.

• Count the number of slices and select the one with the least number of segments.

What is the difference between qualitative and quantitative data in graphs?

• Qualitative data represents numerical values, while quantitative data represents categories or qualities.

• Qualitative data represents categories or qualities (e.g., colors, names), while quantitative data represents numerical values (e.g., counts, measurements).

• Qualitative data is always represented in pie charts, while quantitative data is represented in bar graphs.

• Qualitative data can only be collected through surveys, while quantitative data can be collected through experiments.

How do you calculate the percentage of a category in a circle graph?

• Multiply the value of that category by the total value and divide by 100.

• Divide the value of that category by the total value and multiply by 100.

• Add the value of that category to the total value and multiply by 100.

• Subtract the value of that category from the total value and multiply by 100.

What is the purpose of a bar graph?

• To display data in a circular format

• To compare different groups or categories

• To show trends over time

• To represent data in a three-dimensional space
