It is false that for visualizing the relationship between a numerical and a categorical variable, a mosaic
plot is useful. This is because the best plot to use for this kind of
relationship is the side by side box plot.
Comparing the
distribution of a numerical variable across the levels of a categorical
variable is something we usually consider in this type of relationship.
The levels of one categorical variable by means of a quantitative
variable is best compared by using the visual display called the side by side
boxplot. <span>By placing single boxplots adjacent to one
another on a single scale, the side by side box plot is constructed.</span>

Each <u>family</u> of f<u>unctions</u> has a <u>parent function</u>. A parent function is the <u>simplest function</u> that still satisfies the definition of a certain type of function.
A. this function is linear function;
B. This function is absolute value function and is known to be parent function, because it is of the simpliest form.
C. This function is also absolute value function, but is not of the simpliest form (parent function y=|x| is streched by factor 3 to form y=3|x|).
D. This function is quadratic function.
Answer: correct choice is B
