Copy out your survey data into a new table, make sure your table looks like this:

|Category |Freq |Pie Chart Workings |Angle |

| | | | |

You also need to know the TOTAL of how many people you asked.

• Work out how many degrees represent one person (CALCULATOR) by doing

360 ÷ total

• Write this answer in the Pie Chart Workings space for each category

• To find the Angle multiply the number in the Pie Chart Workings column by the number in the Frequency column

• Check that your angles all add up to 360º
