which of these scatterplots shows a negative correlation? (1 point)
which of these scatterplots shows a negative correlation? (1 point)
Answer
Explanation:
Step1: Recall negative - correlation concept
In a negative - correlation, as one variable increases, the other variable decreases.
Step2: Analyze first scatter - plot
In the scatter - plot of "Number of Toys" vs "Price ($)", as the price increases, the number of toys decreases. This shows a negative correlation.
Step3: Analyze second scatter - plot
In the scatter - plot of "Number of Swimmers" vs "Water Temperature (°F)", as the water temperature increases, the number of swimmers increases. This is a positive correlation.
Step4: Analyze third scatter - plot
In the scatter - plot of "Hair Length (in.)" vs "Height (in.)", there is no clear trend of increase or decrease as one variable changes. There is no correlation.
Step5: Analyze fourth scatter - plot
In the scatter - plot of "Height of Ball (in.)" vs "Time (s)", there is no clear pattern of one variable increasing while the other decreases. There is no correlation.
Answer:
The scatter - plot of "Number of Toys" vs "Price ($)" shows a negative correlation.
