Answer 1

27 (a)

Here planning and evaluation focus on individual rather than community.

28(a)

Pilot study can validate.

Other methods are face validation,content validation (experts).

29.(e)

Primary source are subjective data, experiment,legal document, survey , interview etc.

Secondary sources are report about original, summary,data collected by others etc.

30.(e)

Random selection, probability sampling is used in experimental research study. Experimental study could not be done with non probability research design like snowball and convenience sampling.
