Mnemonic Monday - PED Calculation
Recommend on Google+
Whilst marking hundreds of OCR papers over the summer, I noticed a lot of students understood PED but mistakenly put price on the top of the calculation and quantity on the bottom. Here is a very simple way to make sure pupils always put % change in quantity on the top and % change in price on the bottom for PED.
Formula for PED
Always make sure quantity is on top and price is on the bottom
