How do you find the mean from a histogram?
hi this is 4 my GCSE maths
basically it is asking me to find the mean number of price paid for a camera from a histogram which i have already done
i have the columns frequency, columns width, frequency density
how to i get the mean????????
mean is the average, you add up all the prices and divide by how many cameras you have
