Question

which of the following best explains why one graph appears skewed and one graph appears symmetrical? the scale of the box - and - whisker plot does not start at zero. the interval of the box - and - whisker plot is too large. the interval of the stem - and - leaf plot is not consistent. the scale of the stem - and - leaf plot is too small for the set of data.

Explanation:

Step1: Analyze box - and - whisker plot scale

The starting point of the scale in a box - and - whisker plot does not directly cause skewness or symmetry appearance. For example, a non - zero starting scale can still represent symmetric data accurately.

Step2: Analyze box - and - whisker plot interval

The interval size in a box - and - whisker plot mainly affects the visual spread but not the skewness or symmetry nature of the data representation.

Step3: Analyze stem - and - leaf plot interval

The consistency of intervals in a stem - and - leaf plot is crucial for an accurate visual representation of data distribution. If the intervals are not consistent, it can distort the visual perception of the data's symmetry or skewness.

Step4: Analyze stem - and - leaf plot scale

The scale size of a stem - and - leaf plot being too small does not typically cause an incorrect perception of skewness or symmetry.

Answer:

The interval of the stem - and - leaf plot is not consistent.
