So we pay full concentration while solving assignment of code 1430 for autumn 2016 for aiou students. The basic topics which are discussed in this assignment is point estimation and interval estimation. Point estimation describes the parameters of population which deals the single value of a statistics. While the second part which is explain in this assignment of aiou code 1430 subject is interval estimation. In interval Estimation two number between population parameters.

Point Estimate and Interval Estimate

An estimate of a population parameter may be expressed in two ways:-

A point estimate of a population parameter is a single value of a statistics. Example:- the sample mean X bar is a point estimate of the population means µ. Similarly, the sample proportion p is a point estimate of the population proportion P.

INTERVAL ESTIMATION

An interval estimate is defined by two numbers, between which a population parameter is said to lie.

For Example a < x < b is an interval estimate of the population mean µ. It indicates that population mean is greater than a, but less than b.

In any estimation problem, we need to obtain both a point estimate and an interval estimate. The point estimate is our best guess of the true value of the parameter, while the interval estimate gives a measure of accuracy of that point estimate by providing an interval that contains plausible values.
