thank for your good work, but i have a question, if i have 2 plate, first plate grow 30 coloni, second plate growed 300 coloni, how to caculate cfu/ml (1ml/plate, firt plate 10^2, second plate 10^3 )
I don't think a graph is necessary. Beacuse you are supposed to get one viability count for one particular sample. However, if you have more than one sample, for instance, soil samples from multiple places, then you can make a graph using Microsoft Excel or graphpad prism. For a graph you need multiple samples to compare.

Thank for your good work it's so benefits 👏
but l think the volume of H2O of the third tube should be 9ml so the final volume is 10ml shouldn't be?
Yeah, that should have been 9 ml. Thanks for noticing.
And thank you for the appreciation. Please share the videos 😊
I think 3rd Testube have 1/11?
Yea..same
That was very helpful thank you so much
Glad it was helpful!
No, the middle one is 1/11. The total was supposed to be tenfold.
What if all of the plates are within range. What do you do
You can take middle one.
Thank you for the video
Glad I could help
After this, how can we represent this data with the help of graph
