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 (X1), number of seed-vessels (X2) and the height of the plant (X3):
find out the regression equation of X1 (yield of cotton) on X2 (number of seed, vessels) and X3 (height of the plant). As well find out the partial correlations and the multiple correlations of regressions of X1 on X2 and X3.
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.
