Test: Sampling Theory - 4 - CA Foundation

In stratified sampling, the sampling is subdivided into several parts, called

The no of types of random sampling is

Random numbers are also called Random sampling number Rs.

Sample mean is an example of

Population mean is an example of

Large sample is that sample whose size is

Standard error of mean may be defined as the standard deviation in the sampling distribution of

If random sampling with replacement is applied, then the mean of sample means will be ______ the population mean

The sample proportion is taken as an estimate of the population proportion of defectives

The main object of sampling is to state the limits of accuracy of estimates base on samples

The sample is a selected part of the

The ways of selecting a sample are

__________ sampling is the most appropriate in cases when the population is more or less homogeneous with respect to the characteristic under study

Random sampling is called lottery sampling

___________________ sampling is absolutely free from the influence of human bias

The standard deviation in the sampling deviation is called

Standard error is used to set confidence limits for population parameter and in tests of significance

In _______ estimation, the estimate is given by a single quantity

The estimate of the parameter is stated as on interval with a specified degree of

The interval bounded by upper and lower limits is known as

Statistical hypothesis is an

A die was thrown 400 times and ‘six’ resulted 80 times then observed value of proportion is

 the criteria for an ideal estimator are

 The magnitude of standard error increases both by absolute and relative size of the sample.

The standard deviation of sampling distribution  is known as:

A parameter may be defined as a characteristic of a population based on ____________ of the population

It is know that the 95%LCL and UCL to population mean area 48.04 and 51.96 respectively. If the sample size is 100, what will be the value of the population S.D.

Sample in which number of units is less than _______ is called a small sample. 

Method used to test the human blood is called in Statistical terminology _______

Sampling is a tool which helps to know the characteristics of the  _______ by examining only a small part of it. 

Which of the following is non-probability sampling method?

If the points of inflexion of a normal current are 6 and 14 respectively, then its standard deviation is __________

 A __________is a complete or whole set of possible measurements/data corresponding to the entire collection of units. 

A sampling techiques providing separate estimates for population means for different segments and also an overall estimate is:

There are 75 students in a class and their average marks  is 50 and standard Derivation of Marks is 5. Number of students who have secures more than 60 marks (given that area under the normal curve for z = z is 0.4772 is  __________

 A selection procedure of a sample, having no involvement of probability is known as:

The errors other than sampling error are termed as:
