Question

6. The scatter plot shows the mean annual temperature at different elevations.
Select all the observations that are true about the scatter plot. Lesson 4-1
The majority of the elevations are in a cluster between
1,250 meters and 2,250 meters.
There is a gap in the data between 500 meters and 1,250 meters.
There is an outlier at about (50, 21).
In general, the mean annual temperature decreases as the
elevation increases.
Because there is a gap in the values, there is no association between
the temperature and elevation.

Answer 1

True:
- The majority of the elevations are in a cluster between 1,250 meters and 2,250 meters. (Most points fall in that elevation range.)
- There is a gap in the data between 500 meters and 1,250 meters. (No points appear in that interval.)
- There is an outlier at about (50, 21). (One point is far from the others near elevation 50 m and temperature ~21.)
- In general, the mean annual temperature decreases as the elevation increases. (The pattern shows a negative association.)

False:
- Because there is a gap in the values, there is no association between the temperature and elevation. (A gap does not eliminate the clear negative association visible in the plot.)
