Data is collected on the frequency of mountain bird songs at three different elevations. Data is collected from 100 birds at each elevation.

Question

Low altitude: 80 below 1500 Hz
Medium altitude: 50 below 1500 Hz
High altitude: 20 below 1500 Hz

How does altitude relate to song frequency of birds?

Responses

Higher altitudes are correlated with lower song frequencies.
Higher altitudes are correlated with lower song frequencies.

Altitude does not affect bird song frequencies.
Altitude does not affect bird song frequencies.

Medium altitude has medium frequency songs.
Medium altitude has medium frequency songs.

Higher altitudes are correlated with higher song frequencies.

Answer 1

Based on the data provided, the relation can be interpreted as:

Higher altitudes are correlated with lower song frequencies.

This is evident from the data showing that at low altitude, 80 birds sang below 1500 Hz, while only 50 at medium altitude and 20 at high altitude did the same. This suggests that as altitude increases, the frequency of bird songs tends to decrease.
