What does it mean if a data distribution is symmetrical?

Back

A symmetrical distribution has a mirror image on either side of the center point, meaning the mean, median, and mode are all equal.

What does it mean if a data distribution is skewed right?

Back

A right-skewed distribution has a longer tail on the right side, indicating that the mean is greater than the median.

Front

What does it mean if a data distribution is skewed left?

Back

A left-skewed distribution has a longer tail on the left side, indicating that the mean is less than the median.

How do you determine the shape of a data distribution?

Back

The shape can be determined by analyzing the frequency of data points and their spread, often visualized using histograms or stemplots.

What is a stemplot?

Back

A stemplot is a graphical representation of data that displays the distribution of data points by separating each value into a stem (the leading digit) and a leaf (the trailing digit).

If the mean is less than the median, what can be inferred about the data distribution?

Back

If the mean is less than the median, the data distribution is likely skewed left.
