data is randomly picked in a given population, there arise some

differences in the statisticalvalues computed due to the fact that

there was a lot of randomness in during data collection. Assuch,

different values are arrived at as compared to the values of the

whole population and this isknown as sampling error. Sampling

Distribution of Sample Means is computed by taking thevariance of

the population dividing it by size of the sample. Population

distribution of variouspopulations assumes a bell-shaped. This

bell-shaped curve is more pronounced for a populationof 30 and more

and hence the bigger the sample the greater more pronounced is the

bell shape.The population distribution sample mean tends to be

similar to the normal distribution as thesample size approaches 30.

This describes the concept of Central Limit Theorem. The equationof

the Standard Error of the Mean n indicates that as the population N

gets larger, the standarderror of the mean gets smaller. This is so

since many data points reduce the deviation from thefinal me …
