Sampling variability
Sampling variability
Explanation / Answer
The reasons behind getting different results are
1. Sample to sample variation collected from two different cities.
2. Sample must be selected so that it is a good representative of entire sample
3. Sample size must be sufficiently large..
i.e if you population is huge there your sample must be sufficiently large to represent the entire (all characteristics of) population.
As you increase the the sample size your results becomes more consistent throughout the samples & sample to sample variation reduces.
