BySampling Distributions. Sampling Distribution Introduction. In real life calculating parameters of populations is prohibitive because populations are very large.

ByEstimating Population Parameters. Estimating Population Proportion. The sample is a simple random sample The conditions for the binomial distribution are satisfied. There are at least 5 successes and 5 failures. Requirements:.

ByEstimating Parameters. Parameter Estimation. We use statistics to estimate parameters, e.g., effectiveness of pilot training, psychotherapy. We want to know how good our estimates are.
