Sampling

What do the box plots tell you about the growth of a typical plant species?

• B typically grows taller than A since the range for B is greater.

• B typically grows taller than A since the IQR for B is greater.

• A grows taller than B since the median for A is greater.

• A typically grows taller than B since the mean for A is greater.

What do the box plots tell you about the variability of the data?

• B has greater variability because its range and IQR are greater than A.

• B has greater variability because its median & mean are greater than A.

• A has greater variability because its range & IQR are greater than B.

• A has greater variability because its median and mean are greater than B.
