Microbiologists are essential in helping us to treat diseases. Many work as biomedical scientists in hospitals and laboratories: testing samples of body tissue, blood and fluids to diagnose infections, monitor treatments or track disease outbreaks.
Quantitative measurements are those that deal with a quantity, for example:
Mass of as sample
Length of a piece of wire
Molecules in a mole
Volume of a gas
Temperature of a sample
These types of measurements are called Extensive.
Qualitative measurements are those that deal with the quality, for example:
Color of a sample
Texture of a surface
Coarseness of a powder
Aroma of a reaction
Malleability of a metal
These types of measurements are called Intensive.
