AP Biology Experimental Design and Variables

A young student wants to measure the percent time a dog spends sleeping, playing, and eating over the course of one day.  What type of graph should this student make once all of the data is collected?

• pie/circle
• bar
• line
• scatter plot

What is an independent variable?

• the variable that changes because another variable changes

• independent variables are only found on pie charts.

• a variable most often found on the y-axis

• the variable the experimenter manipulates or has control over
