Question

donnas class measured the widths of 9 buttons.
draw a dot plot for the widths of the buttons. (a dot plot is sometimes called a \line plot\.)
widths of buttons (in inches)
\\(\frac{2}{4}\\) \\(\frac{2}{4}\\) \\(1\frac{1}{4}\\) \\(1\frac{1}{4}\\) \\(1\frac{1}{4}\\) \\(1\frac{2}{4}\\) \\(1\frac{3}{4}\\) 2 2

0 \\(\frac{1}{4}\\) \\(\frac{2}{4}\\) \\(\frac{3}{4}\\) 1 \\(1\frac{1}{4}\\) \\(1\frac{2}{4}\\) \\(1\frac{3}{4}\\) 2
widths of buttons (in inches)

Explanation:

Step1: Count each width frequency

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

Step2: Plot dots on the number line

Place dots above each corresponding width on the axis:

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

Answer:

The completed dot plot will have:

• 2 dots positioned above $\boldsymbol{\frac{2}{4}}$
• 3 dots positioned above $\boldsymbol{1\frac{1}{4}}$
• 1 dot positioned above $\boldsymbol{1\frac{2}{4}}$
• 1 dot positioned above $\boldsymbol{1\frac{3}{4}}$
• 2 dots positioned above $\boldsymbol{2}$

(Visual representation: On the provided number line, mark the appropriate number of dots above each labeled width value as counted.)
