Aiou Solved Assignment 1 Statistic Code 395 Autumn 2016 find here with complete solution. This aiou assignment code 395 solution has a question about estimator and estimate. This topic is very interesting and nice so you can find it on aiou solved assignment 1 for the code 395 for the semester autumn 2016.

AIOU SOLVED ASSIGNMENT 1 STATISTIC CODE 395 AUTUMN 2016 ESTIMATOR AND ESTIMATE

Aiou assignment explain this topic as an estimator is a method for estimating the estimand. While an estimate is a numerical estimate of the estimand that results from the use of a particular estimator. For example, suppose we are interested in the mean height of all male adults in the United States. Our estimand is “the mean height of all male adults in the United States”. A foolproof way to find this mean exactly would be to measure the hight of each and every male adult in the United States and compute the mean. But that sounds too hard, so instead we decide to estimate the mean height by taking a random sample of male adults in the United States and meansuring the height of each individual.

AIOU SOLVED ASSIGNMENT 2 CODE 395 AUTUMN 2016

Suppose we take a random sample of 100 adult men in the United States and measure their heights. Using this data, we now have to choose an estimator that will provide us with an estimate of our estimand.

AIOU SOLVED ASSIGNMENT 1 STATISTIC CODE 395 AUTUMN 2016 SAMPLE AVERAGE

The most obvious thing to do would be to compute the sample average of the heights. That is, “the sample average” is an estimator that provides an estimate of our estimand. Suppose the sample average is 70 inches. Then 70 inches is the estimate of our estimand provide by the sample average” estimator”.
