How Would You Describe Bacteria Using Qualitative Observations
Observation is a useful qualitative data collection method especially when you want to study the ongoing process situation or reactions on a specific issue related to the people being observed. For example when a researcher pays equates research variables in terms of their quality then this is qualitative observation.

Qualitative research presents best examples of raw data to demonstrate an analytic point not simply to display data.
. Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities. Assessing the growth of a bacterial sample provides examples of both types of analysis techniques. Professor and Microbiologist at Department of Microbiology and Immunology Patan Academy of Health Sciences Nepal.
An example of a qualitative technique would be the growth of a bacterial sample on a solid growth medium in order to solely assess whether the bacteria in the sample are living or dead. Numbers descriptive statistics help your reader understand how prevalent or typical a finding is. Up to 24 cash back In other words which place has the most bacteria or microbes and was that what you had predicted based on what you have observed.
If you are conducting an experiment using the scientific method for example you want to record your observations and data as thoroughly as possible. Microorganisms can be classified on the basis of cell structure cellular metabolism or on differences in cell components such as DNA fatty acids pigments antigens and quinones. Overlap the step 2 streak 3-4 times and spread over the surface.
Qualitative data could include its fur color and the color of its eyes whether its fur is soft or rough the sounds it. Key features of these bacterial colonies serve as important criteria for their identification. I am Tankeshwar Acharya.
They do not include precise measurements or numbers. Even when you want to understand peoples behavior or their way of interaction in a particular community or demographic you can rely on the. In contrast qualitative observation focuses on the characteristics of specific events or experiences.
Various steps involved in the identification of unknown bacteria are. Lets say you want to describe a cat. Bacteria are single-celled micro-organisms which are invisible to the naked eye.
I am working as an Asst. You must cite each Petri dish section and the qualitative data that proves your claim. A colony is defined as a visible mass of microorganisms originating from a single mother cell.
To gain a better understanding of the difference. Numbers are helpful and should not be avoided simply because this is a qualitative dissertation. Blogging is my passion.
Qualitative Observation is the research process of using subjective methodologies to gather information or data. Determine and describe the specific EVIDENCE that you used to make your Claim. Overlap the step 1 streak 3-4 times to pull out a reduced number of bacteria and spread them out down the side of the plate.
A device that counts microscopic particles. People observe things based on their surroundings their experiences in life and their developed and. They are classified under plants and not animals due to similar resemblances.
For example it could be notes taken during a focus group on the quality of the food at Cafe Mac or responses from an open-ended questionnaire. But many bacteria infect humans and animals causing deadly diseases. What might the REASONING be for your EVIDENCE.
However when a researcher measures the number of variables using. You will identify and categorize different bacterial colonies based on varied appearance and morphology form and structure When a single bacterial cell is deposited on the surface of a nutrient medium agar it begins to divide exponentially. Qualitative observations are descriptive observations made with our senses of sight taste hearing smell and touch.
Simply put quantitative observation is an objective method of data gathering while qualitative observation is a subjective method of data gathering. They can act as parasites in almost all the organs of the human body. The lowest MIC does not always correlate to the most effective treatment as different antibiotics achieve different concentrations in different sites.
You would use both types of data. The importance of this step is to isolate pure colonies of bacteria. Colonies are described on the basis of size shape texture elevation pigmentation.
Consider this step 2. Colony morphology can sometimes be useful in bacterial identification. Flame the loop and cool it in the agar.
62 To determine qualitative categories specific MIC values also known as breakpoints are used to classify bacteria as susceptible intermediate or resistant to a specific antibiotic. An example of a quantitative technique is the use of that. Quantitative observation is the type of observation that deals in quantifiable variables things that you can use numbers to express.
There are two kinds of observations qualitative and quantitative. A petri dish with a growth medium. Flame the loop and cool it in the agar.
After thousands of cells are formed a visible mass appears which is. Up to 24 cash back Analyzing Observing Bacteria Colonies. Research Methods in the Introduction to Community Psychology describes the ecological lens in community research.
Observation is the basic fundamental of a case study or a research. The hemocytometer works by creating a volumetric grid divided into differently sized cubes for accurately counting the number of particles in a cube and calculating the concentration of the entire sample. Qualitative observations were made on the tests which were compared to unknown bacteria identification key to aid with the identification process.
It is collected using questionnaires interviews or observation and frequently appears in narrative form. Since the focus on qualitative observation is to equate quality differences it is a lot more time consuming than quantitative observation but the sample size used is much smaller and the research is extensive and a lot more personal. The Action Catalogue is an online decision support tool that is intended to enable researchers policy-makers and others wanting to conduct inclusive research to find the method best suited for their specific project needs.
Qualitative data describes qualities or characteristics. Two types of observations. Observation is necessary when it comes to scientific research and studies.
To determine breakpoints the. Qualitative research methods are a key component of field epidemiologic investigations because they can provide insight into the perceptions values opinions and community norms where investigations are being conducted Open-ended inquiry methods the mainstay of qualitative interview techniques are essential in formative research for exploring contextual factors and.
