Conducting Business Research - Essay Example r sample size results in a higher confidence interval; this explains the degree to which the research findings are precise and reliable (Zickmund & Babin, 2007). Lastly, the researcher has to consider the confidence level in the research findings. In most cases, researchers do prefer a higher sample group to achieve a 95 percent confidence level, though the decision is usually based on convention and may not be an important parameter. Determining the sample size is, in most cases, a tricky step in the research process. After considering the above factors, which are the heterogeneity of the population in the study, has to be done, the magnitude error and the confidence level, a researcher can then decide on the right sample size. Therefore, to determine the best sample size, the researcher has to have facts about the homogeneity of the community before the research and then decide on the magnitude error allowable in the research. If the research is convinced that the population is homogeneous and the research needs a low error magnitude, the researcher has to use a much lower sample size when in a heterogeneous population. Determination requires proper investigation about the area in which the researcher has to undertake the business

Measurements, Micropipetting, and Sterile Techniques Essay

Measurements, Micropipetting, and Sterile Techniques - Essay Example 7. Reset the numbers in the window to read 020 (fig.). Write 020 and your name on another piece of filter paper. Follow steps 3-5 to transfer this volume of liquid to the filter paper. What volume in ÃŽ ¼l does 020 represent? 8. Now reset the numbers in the window to read 024 (fig.). Write 024 and your name on another piece of filter paper and follow steps 3-6. What volume in ÃŽ ¼l does 024 represent? By this experiment we measured very small volumes of liquids and gels like DNA. Proper pipetting and sterile technique is essential for correct result. If there is any inaccuracy in pipetting or in sterile technique then it may cause poor and incorrect results. By using sterile technique we developed an ideal environment which protects our sample from contamination. If we put our finger on the tip of the pointed end then sample becomes contaminate. Many laboratory experiments based on the microbiology or on the micro chemical protocols and small volume of DNA has to measure with pure cultures which is done with the help of two techniques-Micropipetting and sterile pipetting. These techniques take us towards nearer to the correct results. Use of these techniques is very important for the better result. We can obtain ideal environment by this method ‘Sterile Technique’. This helps us to gain better results. It means that in this process sterile surfaces or sterile media is protected from contamination by microbes. It is very necessary to maintain sterile conditions properly to reduce the probability of contaminating with bacteria and fungus. By using these methods we can measure small volumes also. Small volume
