Yes. Maths for research and stats. Chemistry in terms of the brain, hormones, nervous system.
There’s a huge difference between researching statistics for psychology to being an Applied Mathematician who uses
techniques, such as mathematical modelling and computational methods to formulate and solve practical problems in business, government, engineering, and the physical life. They have to analyse the most efficient way to schedule airline routes, the aerodynamic characteristics of an experimental automobile, the cost-effectiveness of alternative manufacturing processes...the effects and safety of new drugs..
They also work in industrial research and development where they develop mathematical methods when solving a difficult problem. Some mathematicians — called cryptanalysts — analyse and decipher encryption system & code designed to transmit military, political, financial, law enforcement etc...
Applied mathematicians start with a practical problem, envision its separate elements, and then reduce the elements to mathematical variables. They often use computers to analyse relationships among the variables, and they solve complex problems by developing models with alternative solutions.
I don’t see how looking up or researching statistics can be classed as needing vast knowledge in mathematics...
As an aside, my maths isn’t the best, but it’s been good enough for me to learn to fly both single and twin engine aircraft and fly myself cross country, and over the channel to France, Jersey etc...but I couldn’t possibly envisage learning how to be a cryptanalyst mathematician 😌
