Interpreting graphs and scatterplots

Front

What does it mean if a graph is skewed right?

Back

A skewed right graph has a longer tail on the right side, indicating that most data points are concentrated on the left.

Front

What does it mean if a graph is skewed left?

Back

A skewed left graph has a longer tail on the left side, indicating that most data points are concentrated on the right.

Front

What is a symmetric graph?

Back

A symmetric graph is one where the left and right sides are mirror images of each other.

Front

What is a normal distribution?

Back

A normal distribution is a bell-shaped graph where most data points cluster around the mean.

Front

What is a positive correlation?

Back

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

Front

What is a negative correlation?

Back

A negative correlation means that as one variable increases, the other variable decreases.

Front

What does 'no correlation' mean?

Back

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

Front

What is an undefined slope?

Back

An undefined slope occurs in a vertical line, where the x-value does not change.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatterplot.

Front

How do you determine the best line of best fit?

Back

The best line of best fit minimizes the distance between the line and all data points.
