Learning Target• I can interpret and draw conclusions from
data.

Show what you know!• Answer these questions about the graph
below:• How much rain fell in Mar of 1989?• How much more rain fell in Feb of 1990 than in Feb of
1989?• Which year had the most rainfall?• What is on average the wettest month on the graph?

Show what you know!Answer these questions about the data table:• What is the independent variable on this
table?• What is the dependent variable on this table?• How many elements are represented on the
table? (remember that chemical elements are differentiated by the number of protons in their nucleus, also called the atomic number)
• Which element has the highest ionization energy?
• Describe the shape of the line graph that this data would produce?
Atomic Number Ionization Energy(volts)
2 24.464 9.286 11.228 13.5510 21.47

Check your answers!• What is the independent variable on this table?
Atomic Number• What is the dependent variable on this table?
Ionization Energy• How many elements are represented on the
table? 5 • Which element has the highest ionization
energy? 2 (He)• Describe the shape of the line graph that this
data would produce? Downward Curve or V

Reading Tables• You will HAVE to be able to do this to do well
on the ACT!• Read the questions first, so you know what
information to look for• Read the title or description of the table
before looking at the data so you know what information is being presented in the table.• The more you practice this, the better you will
get.

Reading Graphs• Determine what the graph is telling you. Look
at the passage/description and the title• Look at the units of measurement• Sometimes ACT questions/answers will use different
measurements that what you see in the table/graph. Don’t let them trick you!
• Look for trends in the data• Is there a correlation? What kind of correlation is it?

Positive and Negative CorrelationsPositive• As the value of the
IV increases, the value of the DV increases
Negative• As the value of the
IV increases, the value of the DV decreases

What type of correlation would this be?

Remember• Tables and Graphs are meant to make your
life easier!• Always know what information the table or
graph is showing you• The more you work with tables and graphs,
the less intimidating they become!
