Hi guys,
For the microbial testing of food and water experiment what are the ways that the experiment can be more valid, accurate and reliabe.
-
A generic one but always valid is to run each batch of tests in duplicate or triplicate - this helps determine if there is outliers in the data too. :)
Aseptic conditions can also increase the reliability of microbial analysis results :D
-
Inclusion of both positive and negative controls is another thing you could consider

What do you mean by POSITIVE and NEGATIVE controls

What do you mean by POSITIVE and NEGATIVE controls
Negative control: a control group in an experiment that uses a treatment that isn't expected to produce results
Positive control: a control group in an experiment that uses a treatment that is known to produce results
Hope that helps! :)
