These samples must also be random. They do not need to have the same number of elements, but the ANOVA works better if they are close.
They population from which the random samples come should be normally distributed. Larger sample sizes that are nearly equal in size allow for some departure from the normal distribution requirement.
The ANOVA works best when all the samples have the same standard deviation. One rule of thumb is that the largest standard deviation should not be more than double the smallest standard deviation.
The result of this ANOVA is that the mean ages at death are different. The ANOVA test does not tell specifically which ages are different. A t-test between each pair of ages is needed for more conclusive results....
