The term "IMViC" is an acronym for each of these tests. "I" is for indole test; "M" is for methyl red test; "V" is for Voges-Proskauer test, and "C" is for citrate test. The lower case "i" is merely for "in" as the Citrate test requires coliform samples to be placed "in Citrate". Triple sugar iron test (TSI), Urease Test and Malonate Test are also included in this test.
For each of the tests, different reagents are added to the species are inoculated and tested.
For Salmonella sp. the IMViC Test result is:
Indole - negative
Methyl red - Positive
Voges-Proskauer - negative
Citrate - positive

Explanation:
I learned about this already, and had to do deep research when I did.
A sample is a random, unbiased selection out of a larger group. An independent variable is one that is changed as to see how it will affect the dependent variable in an experiment.
Hope that helped.
