What do you think of when you hear the word statistics?

Number of Customers = 9
Relative Frequency = $\frac{9}{30}$
Percentage = $\frac{9}{30} \times 100\% = 30\%$
Angle for Pie Chart = $\frac{9}{30} \times 360^\circ = 108^\circ$

Number of Customers = 13
Relative Frequency = $\frac{13}{30}$
Percentage = $\frac{13}{30} \times 100\% \approx 43.33\%$
Angle for Pie Chart = $\frac{13}{30} \times 360^\circ = 156^\circ$

Number of Customers = 8
Relative Frequency = $\frac{8}{30}$
Percentage = $\frac{8}{30} \times 100\% \approx 26.67\%$
Angle for Pie Chart = $\frac{8}{30} \times 360^\circ = 96^\circ$

• Product 1 (9 customers): $30\%$ of the pie, corresponding to an angle of $108^\circ$.
• Product 2 (13 customers): $43.33\%$ of the pie, corresponding to an angle of $156^\circ$.
• Product 3 (8 customers): $26.67\%$ of the pie, corresponding to an angle of $96^\circ$.

1. Draw a circle using a compass.
2. Mark the center of the circle.
3. Draw a radius from the center to the circumference. This will be your starting line.
4. Using a protractor, measure and draw the first angle ($108^\circ$ for Product 1) from the starting line. Draw another radius to mark the end of this sector.
5. From the new radius, measure and draw the second angle ($156^\circ$ for Product 2). Draw a third radius.
6. The remaining sector will automatically represent the third angle ($96^\circ$ for Product 3).
7. Label each sector with the product name and its corresponding percentage. You can also use different colors for each sector.

Here is the completed table with the calculated values:

The pie chart would be drawn using these angles.
