Explanation:

First Sub - Question (Ana's Problem)

A stem - and - leaf plot is good for showing the distribution of data and quickly identifying the most common values (modes) in a data set like the heights of students. A line graph is for showing trends over time, a bar graph is for comparing categories, and a pie chart is for showing proportions of a whole. So for seeing the most common heights, a stem - and - leaf plot is suitable.

A bar graph is ideal for comparing the number of different categories (cats, dogs, rabbits, birds). A line graph shows trends, a pie chart shows proportions, and a dot plot is better for showing the distribution of a single variable. So to compare the number of each animal type, a bar graph is best.

A dot plot is useful for showing the distribution of a discrete variable (number of siblings) and can easily identify the most common number (mode). A line graph is for trends, a bar graph is for category comparison, and a pie chart is for proportions. So for the number of siblings, a dot plot is appropriate.

Answer:

D. Stem & Leaf
