In the first exercise, we will focus on variables and some calculations using arithmetic operators.
Body mass index (BMI) is a value derived from the mass (weight) and height of a person. It is a convenient rule of thumb used to broadly categorize a person as underweight, normal weight, overweight, or obese.
The BMI is defined as
Your task is to create a sheet where you can calculate your BMI by entering your name, height and weight. The calculated BMI should be displayed by the click of a button. A draft to a finished solution is shown below.
Commonly accepted BMI ranges are:
BMI [kg/m2]
Underweight
< 18.5
Normal weight
18.5 - 25
Overweight
25 - 30
Obese
> 30
There are as always a number of ways to solve the task, so don't be alarmed if your answer differentiates from our solution.
To make the answer more informative to the user, we may in addition to the BMI value add the corresponding BMI range (normal weight, underweight etc.). How can we do this?
If we were to store statistics of every calculated BMI in every range, how may we do this?
How could we do the same task without the use of VBA, but only using Excel commands? Is that a better approach to this exact problem, and if so, why?
