Pie Charts - SS2 Economics Past Questions and Answers - page 1

I. Step 1: Identify the variable and categories: The variable is the "percentage" and the categories are the different types of pets: Dogs, Cats, Fish, Birds, and Other.

Step 2: Calculate the angle of each sector: Multiply the percentage of each category by 360° to get the angle of each sector. 

Step 3: Draw a circle: Draw a circle to represent the pie chart.

Step 4: Draw the sectors: For each category, draw a sector in the circle with an angle equal to the angle calculated in Step 2. The sectors should be arranged in a clockwise order starting from the top.

Step 5: Label the chart: Title the chart as "Distribution of Pet owners in the neighborhood" Label each sector with the corresponding category name and percentage.

II.To find the percentage of pet owners who own dogs, we can use the formula:

Percentage = (Number of pet owners with dogs / Total number of pet owners) x 100

Substituting the values from the table, we get:

Percentage = (360 / 1000) x 100 = 36%

Thus, 36% of pet owners in the neighbourhood own dogs.
