(b)

(c)

(d) The five-line stem and leaf diagram in component (c) is the most useful.

Step-by-step solution

These infographics are generally used to track a succession of scoring on athletics, a succession of thermometers or showers during time, or a sequence of teaching academic achievement, to give these few possibilities.

Part (a) Step 2: Explanation

The stem-and-leaf diagram of the percentages with one line per stem is

When there are a lot of facts to evaluate, stem-and-leaf storyline visualizations are usually applied. These infographics are generally used to track a succession of scoring on athletics, a succession of thermometers or showers during time, or a sequence of teaching academic achievement, to give these few possibilities.

Part (b) Step 2: Explanation

The stem-and-leaf diagram of the percentages with two lines per stem is

Part (c) Step 1: Concept introduction

When there are a lot of facts to evaluate, stem-and-leaf storyline visualizations are usually applied. These infographics are generally used to track a succession of scoring on athletics, a succession of thermometers or showers during time, or a sequence of teaching academic achievement, to give these few possibilities.

Part (c) Step 2: Explanation

The stem-and-leaf diagram of the percentages with five lines per stem is

Part (d) Step 1: Concept introduction

When there are a lot of facts to evaluate, stem-and-leaf storyline visualizations are usually applied. These infographics are generally used to track a succession of scoring on athletics, a succession of thermometers or showers during time, or a sequence of teaching academic achievement, to give these few possibilities.
