When dots are close in a line on a graph, they display a ______ correlation.

• Low

• No

• High

What is the purpose of creating a line graph in science?

What is the difference between a line graph and a bar graph?

• A line graph displays data in a continuous manner, while a bar graph displays data in discrete categories.

• A line graph is more suitable for showing trends over time, while a bar graph is more suitable for comparing data at a specific point in time.

• A line graph is used to show the relationship between two variables, while a bar graph is used to compare multiple variables.

• A line graph shows the trend over time, while a bar graph compares different categories.

How can you determine the trend or pattern in data using a line graph?

• Plot the data points and connect them with a bar graph.

• Plot the data points and connect them with a line.

• Plot the data points and connect them with a scatter plot.

• Plot the data points and connect them with a curve.

Which graph is best to display the data shown in the table?

• 
• 
• 
• 

What are the two variables typically represented on a line graph?

• control variable and experimental variable

• input and output

• x-axis and y-axis

What is the best way to label the x-axis and y-axis on a line graph?

• Use clear and concise labels that accurately describe the data being represented.

• Do not label the axes at all.

• Use long and complicated labels that are difficult to understand.

• Use random labels that have no relation to the data.

How can you use a line graph to make predictions or draw conclusions?

• By looking at the colors used in the graph.

• By analyzing the trend, direction, and slope of the line on the graph.

• By counting the number of data points on the graph.

• By measuring the length of the x-axis on the graph.
