Correct Answer: (d) Hearing and responding to increase understanding
Solution:

Empathetic listening in communication means hearing and responding to increase understanding. This approach requires the listner to be fully present and attentive to what the other person is saying.

33. Labour Migration trends can be studied by which one of the following methods of PLA?

Correct Answer: (d) Seasonal calendar
Solution:

A Seasonal calander is a participatory tool to explore seasonal changes. The objective of seasonal diagram is to learn about changes in livelihoods over the year and to show the seasonality of agricultural and non-agricultural workload, food availability, human disease, gender specific income and expenditure, water, forage, credit and holidays. So, the labour migration trends can be studied by seasonal calender.

34. In the context of development communication, the concept that empathy determines how an individual will operate in a chainging world; was given by:

Correct Answer: (c) Daniel Lerner
Solution:

The concept of empathy in development communication was given by Daniel Learner. According to him empathy is a key psycholsocial factor that determine how an individual will operate in a changing world.

35. The study of the cultural, behavioural and sociological aspects of spatial distances between individuals participating in a communication situation is:

Correct Answer: (b) Proxemics
Solution:

Proxemics is the study of how space is used in human interaction. It focuses on cultural, behavioural and sociological aspects of spatial distances between individuals participating in a communication.
• Kinesics is the study of the way in which certain body movement and gesture serves as a form of non-verbal communication.
• Para-language is voice intonation that accompanies speech including voice pitch, voice tone and the rhythm of speech.

36. When one rejects the null hypothesis when it is true, it is called :

Correct Answer: (b) Type I & Error of Commission
Solution:

When one rejects the null hypothesis when it is true it is called type-I & error of commission. When are accepts the null hypothesis when it is false it is called type II error of emission.

37. Which of the following is Not a type of stratified Sampling?

Correct Answer: (c) Non Probability Sampling
Solution:

Non probability sampling is not a type of stratified sampling.
Stratified sampling is a type of sampling method in which the total population is divided into smaller groups or strata to complete the sampling process. Proportionate, disproportionate and optimum allocation sampling are the type of stratified sampling.

38. When the survey design focuses on one time assessment of a characteristic of a sample, representing a population comprising of different sub groups and comparing different sub group related to that characteristic, it is called:

Correct Answer: (a) Cross-Sectional Survey design
Solution:

Cross sectional studies are observational studies that examine the relationship between outcomes and exposure as they exist in a population at a particular point in time. So, when the survey design focuses on one time assessment of characteristics of a sample, representing a population comprising a different subgroups related to that characteristics it is called cross sectional survey design.

39. A researcher prepares an experiment to analyze the effects of five different types of bio-fertilizers on yield of rice crop, considering the varying fertility in different blocks and the effect of varying seeds on the yield. The research design will be called:

Correct Answer: (b) Latin Square (L.S.) Design
Solution:

A latin square design is research design used in experimental studies. It is a systematic way to control for multiple sources of variation or bias in an experimential, especially when there are two or more factors or variable interst. So, for the above experiment Latin square research design will be used.

40. We should design the experiment in such a way that the variations caused by extraneous factors can all be combined under the general heading of "Chance". This is called the Principle of:

Correct Answer: (a) Randomization
Solution:

The principle of randomization involves the allocation of treatement to experimental units at random to avoid any bias in the experiment resulting from the influence of some extraneous unknown factor that may affect the experiment.
