WebbEstimating sample means, proportions and variances. Estimation is used for making decisions about populations based on simple random samples . A truly random sample is likely to be representative of the population; this does not mean that a variable measured on a second sample taken will be the same as the first. WebbHow is the mean calculated? Well, it’s the sum of all the values, divided by their length? So the sum of a vector of 1’s and 0’s will be the total number of 1’s!
