How can I compare bacterial growth curves statistically?
Regarding statistical analysis, I assume that you have about 120 pairs of numbers, so you could use a parametric test (eg. ANOVA paired t-test). However if the numbers are not normally distributed, you will have to go for a non-parametric test (especially the Wilcoxon matched-pairs signed-rank test).
Which is the best test for statistical analysis?
Because the standard deviations for the two groups are similar (10.3 and 8.1), we will use the “equal variances assumed” test. The results indicate that there is a statistically significant difference between the mean writing score for males and females (t = -3.734, p = .000).
How are growth curve studies used in virology?
Growth curve studies are widely used in virology. Growth curve experiments involve infecting cells with a viral stock and monitoring viral replication over time (Delbruck, 1940). Often two conditions are compared, for example, a mutant and wild-type virus or replication in the presence and absence of an antiviral inhibitor.
When to use Fisher’s exact test for statistical analysis?
Again we find that there is no statistically significant relationship between the variables (chi-square with two degrees of freedom = 4.577, p = 0.101). The Fisher’s exact test is used when you want to conduct a chi-square test but one or more of your cells has an expected frequency of five or less.

How does the number of cells in a microbial cell increase?
Microbial Growth: 4Refers to an increase in cell number, not in cell size. 4Bacteria grow and divide by binaryfission, a rapid and relatively simple process. classified into several groups based on their preferred temperature ranges.
How to calculate the population change of bacteria?
Using the bacteria density data applet file that you are running from within Geogebra installed on your computer, create a plot of population change P t + 1 − P t versus population density P t and see if the data is well fit by a line through the origin. Use the spreadsheet panel to calculate the population change P t + 1 − P t as follows.
