Scatter Plot Correlations

Front

What is a scatter plot?

Back

A scatter plot is a type of graph that shows the relationship between two numerical variables by displaying data points on a two-dimensional grid.

Front

What does a positive correlation indicate in a scatter plot?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation indicate in a scatter plot?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does 'no correlation' mean in the context of scatter plots?

Back

No correlation means that there is no apparent relationship between the two variables; changes in one variable do not predict changes in the other.

Front

What is an outlier in a scatter plot?

Back

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

Front

How can you identify a positive correlation in a scatter plot?

Back

A positive correlation can be identified by a pattern where points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatter plot?

Back

A negative correlation can be identified by a pattern where points slope downwards from left to right.

Front

What is a linear relationship in a scatter plot?

Back

A linear relationship is when the data points form a straight line, indicating a consistent rate of change between the two variables.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually represent the relationship between two variables and to identify patterns, trends, or correlations.

Front

What does it mean if a scatter plot has no clear pattern?

Back

If a scatter plot has no clear pattern, it suggests that there is no correlation between the variables being analyzed.
