Question

part b
what do the box plots tell you about the variability of the data?
choose the correct response.

plant b has a greater variability because its range and iqr are greater than plant a.
plant a has a greater variability because its range and iqr are greater than plant b.
plant b has a greater variability because its median and mean are greater than plant a.
plant a has a greater variability because its median and mean are greater than plant b.

<reasoning>

Analyze measures of variability in box plots

\[
\text{Variability} \implies \text{Range and Interquartile Range (IQR)}
\]

Evaluate the given options

\[

$$\begin{aligned} &\text{Option 1: Plant B has greater variability because range and IQR are greater than Plant A.} \\ &\text{Option 2: Plant A has greater variability because range and IQR are greater than Plant B.} \\ &\text{Option 3: Median and mean are measures of center, not variability.} \\ &\text{Option 4: Median and mean are measures of center, not variability.} \end{aligned}$$

\]

Determine the correct choice

\[
\text{Correct Option} = \text{Option 2 (Plant A has a greater variability because its range and IQR are greater than Plant B)}
\]
</reasoning>

<answer>
<mcq-option>Plant B has a greater variability because its range and IQR are greater than Plant A</mcq-option>
<mcq-correct>Plant A has a greater variability because its range and IQR are greater than Plant B</mcq-correct>
<mcq-option>Plant B has a greater variability because its median and mean are greater than Plant A</mcq-option>
<mcq-option>Plant A has a greater variability because its median and mean are greater than Plant B</mcq-option>
