An outlier.

What are the two variables on a scatter plot typically called (the horizontal and vertical axes)?
The horizontal axis (x-axis) typically represents the independent variable.
The vertical axis (y-axis) represents the dependent variable.

True or False:
Bar graphs are best for showing relationships between two quantitative variables.
False. Bar graphs are designed to compare quantities across different categories.

What does "relative frequency" mean in a data set?
Frequency is simply the count of how many times a value appears.
Relative frequency turns that count into a proportion or percentage to show how it relates to the whole group.

What is the purpose of drawing a line of best fit on a scatter plot?
To describe the relationship between two sets of data, allowing you to see trends and make predictions for future or unknown values.

What type of association is this?
Negative association

How does a two-way table help you see associations between categorical variables?
By organizing data into rows and columns, allowing you to compare frequencies between two variables. By calculating relative frequencies, you can identify patterns.
