Question

in terms of displaying data, how is a stem-and-leaf plot similar to a dot plot?

select all the similarities below.

a. both plots can be used to identify unusual data values.

b. both plots can be used to show large amounts of data.

c. both plots can be used to determine specific data entries.

d. both plots show how data are distributed.

Explanation:

• Option A: Both stem - and - leaf plots and dot plots can visually show data points, so outliers (unusual data values) can be identified as they stand out from the main cluster of data.
• Option B: Stem - and - leaf plots and dot plots are more suitable for smaller to moderate amounts of data. For large amounts of data, they can become cluttered and hard to interpret. So this option is incorrect.
• Option C: In a stem - and - leaf plot, we can see the actual data values (the leaves attached to the stem), and in a dot plot, each dot represents a data point, so we can determine specific data entries from both.
• Option D: Both plots give a visual representation of how the data is spread out (distributed), for example, if the data is skewed, or has clusters, etc.

Answer:

A. Both plots can be used to identify unusual data values.
C. Both plots can be used to determine specific data entries.
D. Both plots show how data are distributed.
