Creating a Line Graph

This video tutorial from MooMoo Math and Science explains how to create a line graph. It covers when to use a line graph, how to set up the axes using the DRY MIX method, label them, create a consistent scale, plot data points, connect the dots, and title the graph. The example used is monthly rainfall data for a fictitious city. The video concludes with a summary of the steps and a reminder to be kind.

When is it most appropriate to use a line graph?

• When showing parts of a whole

• When measuring time

• When displaying frequency

• When comparing categories

In the DRY MIX method, where is the dependent variable placed?

• On the x-axis

• On the t-axis

• On the z-axis

• On the y-axis

What does the 'M' in DRY MIX stand for?

• Measured

• Manipulated

• Mixed

• Monitored

What is the first step in creating a consistent scale for a graph?

• Determine the range

• Plot the data

• Draw the graph

• Label the axes

If the highest data point is 7 and the lowest is 1, what is the range?

• 6

• 7

• 5

• 8

How do you determine the value of each space on the graph?

• Subtract the range from the number of spaces

• Divide the range by the number of spaces

• Add the range to the number of spaces

• Multiply the range by the number of spaces

What is the next step after plotting all data points on a graph?

• Change the scale

• Recalculate the data

• Connect the dots

• Erase the graph

What can you observe from a completed line graph?

• The size of the graph

• The color of the graph

• Trends and patterns

• The exact values of data

What is the final step in creating a line graph?

• Replot the points

• Change the data

• Add a title

• Erase the graph

What is a suitable title for a graph showing monthly rainfall in a fictitious city?

• Weekly Rainfall

• Monthly Temperature

• Yearly Rainfall

• Monthly Rainfall for City
