Name two attractive features and two limitations of the (a) stem-and-leaf plot and (b) dot plot.

a.

Expert Solution

To determine

Give two attractive features and two limitations of the stem-and-leaf plot.

Explanation of Solution

Stem-and-leaf plot:

The simple way that is used to visualize the small data sets is termed as stem-and-leaf plot.

The two attractive features are,

It is a tool for exploratory data analysis which reveals the data features.
It divides the data into two parts, such that, stem and leaf.

The two limitations are,

It only works well on small samples.
It is not appropriate for decimal data and multi digit data.

b.

Expert Solution

To determine

Give two attractive features and two limitations of the dot plot.

Explanation of Solution

Dot plot:

One of the simple graphical displays of a group of individual values of numerical data is termed as dot plot.

The two attractive features are,

It is an attractive tool for data exploration.
Outliers are easily identified in the dotplot.

The two limitations are,

It’s not useful to compare more than 2 sequences.
The frequency of a data value is not identified in a dotplot.
