A scatterplot shows points that trend downward from left to right. This indicates the two variables have a:
Answer: Negative correlation
A downward trend means as one variable increases the other decreases—a negative correlation.
In a Conflicting Viewpoints passage, the best way to answer a question asking how Scientist 1 would respond to Scientist 2's claim is to:
Answer: Apply Scientist 1's stated reasoning to the new claim
You must reason from the viewpoint's own logic, not personal opinion.
A table shows that as altitude increases, air pressure decreases. A new measurement at an unlisted higher altitude should have a pressure that is:
Answer: Lower than all listed values
Extrapolating the trend, higher altitude than any listed means lower pressure than any listed.
Which of these is the dependent variable in a study measuring how fertilizer amount affects tomato yield?
Answer: Tomato yield
The dependent variable is the measured outcome—tomato yield.
A graph plots solubility of a salt versus temperature, rising steadily. At an unmeasured temperature between two data points, the best estimate of solubility uses:
Answer: Interpolation between the points
Estimating a value between known data points is interpolation.
An ACT passage reports a measurement of 9.8 m/s². This value most likely represents:
Answer: Acceleration due to gravity
9.8 m/s² is Earth's gravitational acceleration.
If three trials of an experiment give nearly identical results, the data are best described as:
Answer: Precise
Closely repeating results indicate high precision (reproducibility).
