UGC NET Paper1 Previous Year Solved Papers MCQ - 4th December 2019 Evening Shift

Only (c) and (d) are correct.

Subject	Predicate
A: 'birds' refers to all birds; so distributed	does not refer to every 'winged creature' e.g., bats, flying fish; so undistributed
E: refers to all birds by implication as they are not part of the predicate class; so distributed	refers to all wingless creatures by implication that they are not part of the subject class of birds; so distributed
I: refers only to some birds; so undistributed	refers only to some black things--only those that are birds; so undistributed
0: refers only to some birds; so undistributed	refers to all 'black things', none of which is in the subject class of "some birds"; so distributed

Similarly, for the 0 proposition, "Some girls are not students", the subject term 'girls' is not distributed, but the predicate term, 'students' is distributed.

Statements (a) and (c) are correct.
(a) Sampling-related error is subsumed under the category non-sampling error.
(c) Inaccurate sampling frame and non- response are examples of sampling- related error.
Sampling error is the deviation of the selected sample from the true characteristics, traits, behaviours, qualities or figures of the entire population.
Errors which are due to the factors other than sampling are called non-sampling errors. A non-sampling error occurs during data collection, causing the data to differ from the true values. It can be of different kinds. Sampling related error occurs when a unit in the sample is incorrectly excluded or included, or is duplicated in the sample. This happens in case of inaccurate sampling frame OR partial or complete non-response- when data is not obtained owing to absence, non-contact, refusal, or some other reason OR response error caused by respondents providing inaccurate responses, intentionally or accidentally,
Interviewer error caused by incorrect record of information owing to bias, influence or false assumptions.
Processing error that may occur during data collection, data entry, coding, editing or output.

Students'academic performance is an output of their learning ability, motivation, and hard work. However, if the student has a low self-efficacy (belief in his or her capacity to execute behaviours necessary to produce specific performance/ attainments) or the teacher's expectation from him/her is low, it is likely to affect the academic performance considerably. Belief in God is a matter of faith; while indifference towards politics is a matter of choice. Neither has any bearing on a student's academic performance.
