Positive and Negative Relationships in Scatter Plots

Aiden, Henry, and Charlotte are having a friendly competition to see who can best interpret scatter plots. They come across a tricky one and need your help. How can they determine if this scatter plot has a positive correlation?

• They should check if the points on the plot generally decrease from left to right.

• They should check if the points on the plot are randomly scattered.

• They should check if the points on the plot form a straight horizontal line.

• They should check if the points on the plot generally increase from left to right.

Aiden, Maya, and Abigail are having a friendly debate. They are looking at a graph and trying to determine the type of association (correlation) it has. Aiden thinks it's positive, Maya thinks it's negative, and Abigail thinks there's no correlation at all. Can you help them figure out the answer? #18

• positive

• negative

• none

• all of the above

Arjun, Abigail, and Luna are having a debate. Arjun says a scatter plot is used to show the distribution of a single variable, Abigail thinks it's to compare the means of two groups, Luna believes it's to display the trend over time. But, who is correct? What is the actual purpose of a scatter plot?

• To show the distribution of a single variable.

• To compare the means of two groups.

• To display the trend over time.

• To display the relationship between two variables.

David, Ava, and Mia are analyzing a scatter plot. They are discussing the difference between positive and negative correlation. Can you help them understand the difference?

• Positive correlation means one variable increases while the other remains constant, negative correlation means both variables increase.

• Positive correlation means both variables increase, negative correlation means one variable increases while the other decreases.

• Positive correlation means both variables decrease, negative correlation means one variable decreases while the other increases.

• Positive correlation means one variable increases while the other remains constant, negative correlation means both variables remain constant.
