Question

Which of these scatterplots shows a negative correlation?

Number Sold

Price ($)


Number of Swimmers

Water Temperature (°F)


Hair Length (in.)

Height (in.)


Height of Ball (in.)

Time (s)

Answer 1

To determine which scatterplot shows a negative correlation, we can analyze the relationships described:

1. **Number Sold vs. Price ($)** - This typically shows a negative correlation; as the price increases, the number sold often decreases.

2. **Number of Swimmers vs. Water Temperature (°F)** - This may show a positive correlation as warmer water temperatures might attract more swimmers.

3. **Hair Length (in.) vs. Height (in.)** - This relationship does not have a clear expectation for correlation from the variables provided and may not indicate a strong correlation either way.

4. **Height of Ball (in.) vs. Time (s)** - If this relates to a trajectory or bounce, as time increases, the height decreases after reaching a peak, which may indicate a negative correlation.

From this analysis, the most straightforward candidate for showing a negative correlation is the **Number Sold vs. Price ($)** scatterplot.
