How do you calculate sample size?
Count up the number of obseravtions made on the experimental units. That is the sample size.

Does a colony count really give a total count of microorganisms per unit sample of the original material?
A colony count provides an estimate of the number of viable microorganisms that are able to grow under the specific conditions used for culturing. It does not give a total count of all microorganisms present in the sample, as some may not be culturable or may not grow under the conditions used.
What is most viable count?
"Most viable count" is a term used in microbiology to refer to the number of viable microorganisms in a sample. It is often determined through techniques like colony counting on agar plates or turbidity measurements. This count is important for assessing the presence and concentration of microorganisms in a sample.
Method to count the number of bacteria in a sample of water?
One method to count the number of bacteria in a sample of water is through serial dilution and plating. The sample is diluted multiple times and then spread onto agar plates, allowing individual colonies to grow. The number of colonies formed can then be counted to estimate the original bacterial count.
Is an epithelial cell count of 90 per uL cause for concern?
It means the sample is contaminated.
How to find the mitotic index in a cell sample?
To find the mitotic index in a cell sample, count the number of cells undergoing mitosis and divide it by the total number of cells in the sample, then multiply by 100 to get the percentage. This helps determine the rate of cell division in the sample.
What is the function of hemocytometer in cell count?
A hemocytometer is a device with a small, precise grid for which the area and depth are known. It is used to count cells, though was originally used for counting blood cells. By counting the number of cells in a given sample space, a generalization can be made about the population, or entire sample.
What is a coliform count?
A coliform count is a microbiological assay of the number of coliform-type bacteria living in a certain sample. This is often used as a measure of fecal contamination of water supplies.
How is a reticulocyte count conducted?
The first step in a retic count is drawing the patient's blood sample. About 17 oz (5 ml) of blood is withdrawn from a vein into a vacuum tube.
Does the number of bacteria recorded by the standard plate count method accurately reflect the total bacterial count from the sample?
No. The standard plate count method is an indirect measurement of cell density of only viable bacterial cells. Optical density counting measure entire bacterial sample, the living as well as the dead bacterial cells.
What is Quebec colony counter?
A Quebec colony counter is a device that is used to count the number of bacteria colonies in a sample.
