Scatter Plots

Front

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.

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 a scatter plot?

Back

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

Front

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

Back

A strong correlation is identified when the data points are closely clustered around a straight line.

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 variables.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables and to identify trends, patterns, or correlations.

Front

What does it mean if a scatter plot has a weak correlation?

Back

A weak correlation means that the data points are more spread out and do not closely follow a straight line, indicating a less consistent relationship.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.
