Front

What is bivariate data?

Back

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

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for two variables for a set of data, showing how one variable is affected by another.

Front

What does a positive correlation in a scatterplot indicate?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

Back

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

Front

What is an outlier in a dataset?

Back

An outlier is a data point that differs significantly from other observations in the dataset.

Front

How do you determine the line of best fit in a scatterplot?

Back

The line of best fit is determined by drawing a line that best represents the data points, minimizing the distance from the points to the line.

Front

What is a frequency table?

Back

A frequency table is a way to organize data that shows how often each value occurs.

Front

How can you interpret a scatterplot?

Back

You can interpret a scatterplot by looking for patterns, trends, and correlations between the two variables.

Front

What is the purpose of using bivariate data?

Back

The purpose of using bivariate data is to analyze the relationship between two different variables.

Front

What does it mean if a scatterplot has no correlation?

Back

If a scatterplot has no correlation, it means there is no discernible relationship between the two variables.
