problem 1: Describe the objects and categorization of data.
problem 2: describe the sources and uses of the secondary data.
problem 3: describe the reliability and limitations of the scaling methods.
problem 4: Outline various methods of sampling used in research?
problem 5: The given are the observations on 18 cotton plants with respect to the yield of cotton (X_{1}), number of seed-vessels (X_{2}) and the height of the plant (X_{3}):
find out the regression equation of X_{1} (yield of cotton) on X_{2} (number of seed, vessels) and X_{3} (height of the plant). As well find out the partial correlations and the multiple correlations of regressions of X_{1} on X_{2} and X_{3}.
problem 6: What are the various problems in the collection of health statistics?
problem 7: State the usefulness of multi-dimensional scaling in the research.
