Understanding Line Graphs Concepts

The video tutorial explains how to create and interpret a line graph. It begins by describing the essential components of a line graph, such as the title, labels, and scale. An example using daily sunshine hours in Nottingham is provided to illustrate the process. The tutorial guides viewers through drawing the graph, plotting data points, and connecting them to form a line. Finally, it demonstrates how to analyze the graph to determine which day had the most sunshine.

What is the primary purpose of a line graph?

• To compare parts of a whole

• To display changes over a period of time

• To show relationships between different categories

• To illustrate a process or workflow

Which of the following is NOT a necessary component of a line graph?

• A title

• A sensible scale

• A legend

• Labels on both axes

What is the first step in drawing a line graph from a table of data?

• Plotting the data points

• Drawing a sensible scale

• Adding a title

• Connecting the data points

When plotting data points on a line graph, what should you do after labeling the axes?

• Calculate the average of the data

• Add a legend

• Plot the data points from the table

• Draw a line through the points

How do you complete a line graph after plotting all the data points?

• Add a legend

• Erase unnecessary lines

• Connect the points in order

• Add a title

What is the final step in creating a line graph?

• Labeling the axes

• Adding a title

• Connecting the data points

• Drawing a scale

How can you determine which day had the most sunshine hours from a line graph?

• Look for the longest line

• Find the highest point on the graph

• Check the first data point

• Look for the steepest slope

According to the line graph, which day had the highest number of sunshine hours?

• Monday

• Tuesday

• Thursday

• Wednesday
