Graphing Techniques in Biology

The video tutorial introduces biology students to graphing, focusing on the placement of independent and dependent variables on the x and y axes, respectively. It provides mnemonic aids for remembering these placements and discusses the essential elements of a graph, including titles, units, and legends. The tutorial also covers different types of graphs, such as line graphs, scatter plots, bar graphs, and pie charts, explaining their specific uses and characteristics.

What axis is the independent variable (IV) placed on?

• z-axis

• w-axis

• y-axis

• x-axis

Which superhero group is used as a mnemonic to remember the placement of the IV?

• X-Men

• Justice League

• Fantastic Four

• Avengers

Where should the dependent variable (DV) be placed on a graph?

• w-axis

• z-axis

• y-axis

• x-axis

What should be included in the title of a graph?

• Only the IV

• Neither IV nor DV

• Only the DV

• Both the IV and DV

What is essential to label on a graph?

• Graph size

• Graph shape

• Graph color

• Units of measurement

What type of graph shows change over time?

• Pie graph

Which graph type is used to show relationships between two quantitative variables?

• Scatter plot

• Pie graph

• Bar graph

• Line graph

What does a bar graph typically show?

• Change over time

• Percentages
