Scatterplots

Front

What is a scatterplot?

Back

A scatterplot 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 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 does no correlation mean in a scatterplot?

Back

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

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified by a pattern where points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation can be identified by a pattern where points slope downwards from left to right.

Front

What is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually display the relationship between two variables and to identify trends or patterns.

Front

What does the term 'outlier' mean in the context of scatterplots?

Back

An outlier is a data point that differs significantly from other observations in the scatterplot, potentially indicating an anomaly.

Front

What is the relationship between the length of running start and distance of jump in a positive correlation?

Back

In a positive correlation, the further you run, the further you jump.

Front

What type of relationship does a scatterplot with points scattered randomly indicate?

Back

A scatterplot with points scattered randomly indicates no relationship between the variables.
