Question

rafael’s class measured the widths of 8 belts.
draw a dot plot for the widths of the belts. (a dot plot is sometimes called a \line plot\.)
widths of belts (in inches)
$1\frac{2}{4}$ $1\frac{2}{4}$ $1\frac{2}{4}$ $2\frac{1}{4}$ $2\frac{3}{4}$ $2\frac{3}{4}$ $3$ $3$
number line with marks at 1, $1\frac{1}{4}$, $1\frac{2}{4}$, $1\frac{3}{4}$, 2, $2\frac{1}{4}$, $2\frac{2}{4}$, $2\frac{3}{4}$, 3, labeled \widths of belts (in inches)\

Explanation:

Step1: Count each width frequency

• $1\frac{2}{4}$: 3 occurrences
• $2\frac{1}{4}$: 1 occurrence
• $2\frac{3}{4}$: 2 occurrences
• $3$: 2 occurrences

Step2: Match to number line

Place dots above each value on the pre-drawn number line, with the number of dots equal to the frequency of each width.

• Above $1\frac{2}{4}$: Draw 3 dots
• Above $2\frac{1}{4}$: Draw 1 dot
• Above $2\frac{3}{4}$: Draw 2 dots
• Above $3$: Draw 2 dots

Answer:

A dot plot where:

• 3 dots are placed above $1\frac{2}{4}$
• 1 dot is placed above $2\frac{1}{4}$
• 2 dots are placed above $2\frac{3}{4}$
• 2 dots are placed above $3$

on the provided number line labeled "Widths of belts (in inches)".
