An estimate of the adjusted birth rate can be obtained by multiplying each of the adjusted fertility rates by the number of women in the relevant age group to estimate numbers of births, adding these results for all ages and then dividing their sum by the total population.
The margin of error is a statistic expressing the amount of random sampling error in a survey's. Margin of error is positive whenever a population is incompletely sampled and the outcome. It can be estimated from just p and the sample size, n, if n is small relative to the population size, using the following formula:.

• The true error rate is the classifier's error rate when tested on the ENTIRE POPULATION. • If we had access to an unlimited number of – The error rate estimate will be overly optimistic (lower than the true error rate). • In fact, it is not uncommon to achieve 100% correct classification on training data.
