      Use a grid that has a split area into squares. Random coordinates are obtained using a random number generator. The count number (frequency) of plants in a quadrat is gained and the mean number per quadrat is calculated and then the total number of bluebells is calculated by finding the mean number of plants per quadrat and multiplying it by the number of quadrats in the wood.
