Question. 1. Explain briefly why data collection and data analysis should not be separated at the planning stage of any research project.

Answer:The use of qualitative data in social sciences has recently been achieving more and more acceptance and popularity.  It was not used commonly in the past because many researchers were not comfortable with the functionality and analysis of qualitative data.  Qualitative data is data that is expressed in words as opposed to numbers, and it uses less structured and more open-ended methods of collecting data.  However, the appropriate use of this type of data can add richness to an analysis.  They allow for an issue or question to be probed more in-depth than with quantitative data.  Different techniques are used both to collect and to analyze qualitative data.  It is important to note that “qualitative methods do not usually fit with the assumptions or requirements of probability sampling.  Unlike sample-survey methods, qualitative data collection and data analysis are quite labor-intensive, and usually focus on

Question. 2. What do you understand by stratification of a population? Why is it said that stratified sampling improve precision?

Answer:In statistics, stratified sampling is a method of sampling from a population.  In statistical surveys, when subpopulations within an overall population vary, it is advantageous to sample each subpopulation (stratum) independently. Stratification is the process of dividing members of the population into homogeneous subgroups before sampling. The strata should be mutually exclusive: every element in the population must be assigned to

Question. 3. Define Dichotomous data. Mention two reasons which make Guttman scale an impractical tool for the measurements of attitudes.

Answer:A dichotomy is a partition of a whole (or a set) into two parts (subsets) that are:

·         Jointly exhaustive: everything must belong to one part or the other, and

·         Mutually exclusive: nothing can belong simultaneously to both parts.

Such a partition is also frequently called a bipartition.

Question. 4. Two different varieties of mushroom were grown on 6 and 7 plots of the same size. At the end of the crop run, the following quantities of yield were observed for the two varieties:

Variety I 16 12 11 13 15 17

Variety II 11 11 10 15 14 16 10

Using the Mann-Whitney U test, verify at 0.05 level of significance whether the two varieties of mushroom produce the same yield.

Answer:Behavior cannot be predicted from a “connectome” because the brain contains a chemical “map” of neuromodulation superimposed upon its synaptic connectivity map. Neuromodulation changes how neural circuits process information in different states, such as hunger or arousal. Here we describe a genetically based method to map, in an unbiased and brain-wide manner, sites of neuromodulation under different conditions in the Drosophila brain. This method, and genetic perturbations, reveal that the well-known

Question.5.Yours is a consulting organization which undertakes business research studies. A prospective client visits your organization and wants to know the types of job your organization undertakes. What sort of pre-presentation handouts would you prepare before making a presentation to him?

Answer:"It usually takes me more than three weeks to prepare a good important speech." Most good public presentations, no matter how easy or spontaneous they look. require diligent preparation, as well as an understanding of the key principles of presenting — designing the message, engaging the learner, rehearsing the delivery, and mastering presentation skills and technologies.

Emergency medicine academicians speak to a wide range of audiences including colleagues, nurses, paramedics/EMTs, and the lay public. "Academicians should be eager to give lectures because to teach is to learn. Presentations are an excellent opportunity for the presenter to learn, as well as gain feedback and insights from the audience, literally "road testing" the materials. Speaking before a group is also a great motivator to be well prepared. (I have a rule that I never give the same speech twice — i.e., no "canned" presentations
