What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

What does it mean if a scatter plot has no clustering?

Back

It means that the data points are spread out evenly without forming any groups or patterns.

What is a negative association in a scatter plot?

Back

A negative association occurs when one variable increases while the other variable decreases, indicating an inverse relationship.

What is an outlier in a scatter plot?

Back

An outlier is a data point that significantly differs from the other observations in the dataset, often appearing far away from the main cluster of points.

How can you identify outliers in a scatter plot?

Back

Outliers can be identified by looking for points that are distant from the overall pattern of the data.

What does it indicate if the time taken to paint a room increases as the number of people decreases?

Back

It indicates a negative correlation between the number of people and the time taken, meaning fewer people lead to longer painting times.

What does it mean if a scatter plot shows a positive association?

Back

A positive association means that as one variable increases, the other variable also increases, indicating a direct relationship.

What is the significance of the axes in a scatter plot?

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable, allowing for analysis of their relationship.

Front

What is the first step in constructing a scatter plot?

Back

The first step is to collect and organize the data for the two variables you want to compare.
