What is the dependent variable?
the variable that changes as a result of the independent variable manipulation.
What is a control group?

Why is the control group important?
it acts as a benchmark to compare the results of the experiment to
What would be considered the control of the termite experiment?
using a blue colored pencil to see if it actually is attracted to the color or the smell of the pen
Which axis does the independent variable go?
x axis
What is standard deviation?
measure of variation from the mean
What does an overlap in the error bars mean?
the difference between the groups is not statistically significant
What does no overlap in error bars mean?
The difference between the groups is statistically different
What is the difference between line and bar graphs?
bar graphs should be used when the independent variable is grouped, and the line graph should be used when your data quantifies over time
Confidence intervals
overlap inconclusive
What do error bars do?
they show variability
