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 displays values for two variables for a set of data.

Front

What does an outlier represent in a data set?

Back

An outlier is a data point that differs significantly from other observations, often indicating variability or an anomaly.

Front

How do you identify an outlier in a scatter plot?

Back

An outlier can be identified as a point that is far outside the main cluster of points.

Front

What is correlation in statistics?

Back

Correlation measures the strength and direction of a linear relationship between two variables.

Front

What does a positive correlation indicate?

Back

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

Front

What does a negative correlation indicate?

Back

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

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, showing the trend of the data.

Front

How do you determine the equation of the line of best fit?

Back

The equation of the line of best fit can be determined using statistical methods such as linear regression.

Front

What is the purpose of the line of best fit?

Back

The line of best fit helps to predict values and understand the relationship between the two variables.
