A student decided to research primate psychology for their science project. They measured how long it took gorillas to adapt to their new habitat when moved from one zoo to another. They measured how long it took the new gorilla to interact regularly (more than 3 times per day) with the gorillas that already live there. Seven different cases were examined and the data collected. What can be said about the data? [GorillaTime to interact (days)12.523.138.343.352.763.273.4]
Gorilla 1 2 3 4 5 6 7 Time to interact (days) 2.5 3.1 8.3 3.3 2.7 3.2 3.4
A. The data falls within similar ranges so it may be reliable.
B. The data is only measured to one decimal place, so it is not reliable.
C. The data may not be reliable because there is an outlier.
D. The data is reliable because there is only one outlier.
The correct answer is D. The data is reliable because there is only one outlier. The outlier is gorilla 3, which gained 8.3.
