A fifth grade class conducted a 5-minute experiment that involved heating time and water temperature.  The results of the experiment are represented in this line graph.  What prediction can be made based on the information gathered?

• The water temperature remains the same as the heating time continues.
• The water temperature decreases as the heating time continues.
• A pattern cannot be determined between these measurements.
• The water temperature increases as the heating time continues.

The following scatter plot shows the weights and lengths of some dinosaurs.  Which statement accurately describes the information?

• The information shows a positive correlation.  The weight of a dinosaur tends to increase according to its length.
• The information shows a negative correlation.  the weight of a dinosaur tends to decrease according to its length.
• The information shows no correlation.  The weight and length vary according to the type of dinosaur.
• The information shows no correlation.  The relationship between the weight and length of a dinosaur is uncertain.

The scatter plot shows the number of absences in a week for classes of different sizes.  Trevor concluded that there is a positive correlation.  Which statement best describes why Trevor's conclusion was incorrect.

• The largest class does not have the most absences.
• The smallest class does not have the least number of absences.
• The data show no relationship between class size and number of absences.
• The data show a negative relationship between class size and number of absences.
