Scatterplots

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does it mean if a scatterplot shows a positive correlation?

Back

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

Front

What does it mean if a scatterplot shows a negative correlation?

Back

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

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that differs significantly from other observations in the dataset, often appearing far away from the trend of the data.

Front

How can you identify an outlier in a scatterplot?

Back

An outlier can be identified as a point that is distant from the cluster of other points in the scatterplot.

Front

What does 'no correlation' mean in the context of a scatterplot?

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 a strong correlation?

Back

A strong correlation indicates that the data points closely follow a clear trend, either positive or negative.

Front

What is a weak correlation?

Back

A weak correlation indicates that the data points do not follow a clear trend and are more spread out.

Front

What are coordinates in a scatterplot?

Back

Coordinates are pairs of values (x, y) that represent the position of a point on the scatterplot, where 'x' is the value of the independent variable and 'y' is the value of the dependent variable.

Front

What does the term 'association' refer to in a scatterplot?

Back

Association refers to the relationship between the two variables represented in the scatterplot, indicating how one variable may affect or relate to the other.
