The Post is about Online Estimation MCQs from Statistical Inference covering the topics of Estimates and Estimation for the preparation of exams and different statistical job tests in Government/ Semi-Government or Private Organization sectors. These tests are also helpful in getting admission to different colleges and Universities. The Online Estimation …
An estimator $\hat{\theta}$ is sufficient if it makes so much use of the information in the sample that no other estimator could extract from the sample, additional information about the population parameter being estimated. The sample mean $\overline{X}$ utilizes all the values included in the sample so it is a …
Statistics is a consistent estimator of a population parameter if “as the sample size increases, it becomes almost certain that the value of the statistics comes close (closer) to the value of the population parameter”. If an estimator (statistic) is considered consistent, it becomes more reliable with a large sample …
The objective of point estimation of parameters is to obtain a single number from the sample which will represent the unknown value of the parameter. Practically we did not know about the population mean and standard deviation i.e. population parameters such as mean, standard deviation, etc. However, our goal is …
