During Sаlmоnellа entericа gastrоenteritis (acute inflammatiоn of the intestines, often with nausea, diarrhea, and abdominal pain), responding neutrophils of the immune system generate an oxidizing environment. This environment produces tetrathionate, a compound Salmonella uses as a terminal electron acceptor for anaerobic respiration. Most normal microbiota are unable to use this compound, instead relying on fermentation in this anaerobic environment. In the densely populated intestinal tract, this ______.

1. At the end оf this lessоn, yоu should be аble to Know аnd understаnd how a sample size is determined Understand and compute a sample size using the Cochran's formula and Raosoft calculator Compare the results from the Cochran's calculation with Raosoft result Differentiate the various sampling techniques 2. Discussion question In your submission, write two paragraphs, one of sample size determination and the second on sampling procedure you will use to derive the actual number of participants for your study. The following should be covered 2.1. Sample size determination (Quantitative) Paragraph 1: Sample size calculation How are you going to sample schools, facilities or households (primary sampling unit) from which to derive a certain number of facilities? Which sampling method are you going use and why? How are you going to ensure that the sample to be selected is representative from each primary sampling unit and you do not over- or under-sample from anyone sampling unit? How are you going to calculate your sample size? (Cochran's formula or raosoft sample size calculator) What is the total or estimated number of potential participants What sampling parameters (response rate, confidence interval etc) are you going to use to calculate your sample size What is the final sample size you have obtained Did you include a 10 or 20% buffer to compensate for non-response bias? If you are going to interview participants from clinics or schools or different industries, how are you going to make sure you reduce sampling bias (i.e. you do not over or under sample?) See this video on sampling allocation (https://youtu.be/XitDZqSza5U). If this is not applicable to your, it's still fine, you do not have to have it in your proposal. Paragraph 2 Sampling procedure Based on your final calculated sample size using Raosoft or Cochran's formula, how are you going to sample participants for inclusion in your study? For example, if you get to a clinic or school, how are you going to choose your participants? ------------------------------------------------------------------- OR 2.2. Sample size determination (Qualitative) Paragraph 1: Sample size determination Which sampling method are you going to use and why? What is the maximum number of participants you are going to sample? Data saturation and rule of thumb Paragraph 2: Sampling procedure How are you going to select the participants that will potentially partake in your study? 3. Instructions Do not provide any definitions of terms and concepts. You can provide a justification for choosing a particular sample size and technique. Summarise key issues and ensure that you cover or answer the questions above. Do not write in bullet points but write in a narrated form.
