Front

What is bivariate data?

Back

Bivariate data involves two variables and is used to determine the relationship between them.

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.

Front

What does the line of best fit represent in a scatter plot?

Back

The line of best fit represents the trend in the data, showing the overall direction of the relationship between the two variables.

Front

What is an outlier in a scatter plot?

Back

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

Front

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

Back

A positive correlation is identified when, as one variable increases, the other variable also tends to increase, resulting in an upward trend.

Front

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

Back

A negative correlation is identified when, as one variable increases, the other variable tends to decrease, resulting in a downward trend.

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no discernible relationship between the two variables; the data points do not show any trend.

Front

What are coordinates in a scatter plot?

Back

Coordinates are the ordered pairs (x, y) that represent the position of a point on the scatter plot.

Front

What is the purpose of the line of best fit?

Back

The purpose of the line of best fit is to summarize the relationship between the two variables and make predictions.

Front

What is a linear correlation?

Back

A linear correlation is a relationship between two variables that can be represented by a straight line.
