Is it true that passing data by reference enables you to change the value stored in a variable in one file using a function in another file?
Yes, passing a variable by reference gives you a pointer to the original variable, meaning you can change its value from within the function being called and the change will affect the original variable.
Which of the following is not a variable data type real integer number or string?

Which data type can store any data?

What type of variable in a experiment is the heartbeat?
It depends on whether the heart beat is being changed (dependent variable) or if the heart beat is changing something else (independent variable) P.S. The independent variable is the thing that was changed, while the dependent variable is the data collected through observations and measurements ( aka how the independent changed the dependent).
When data is collected using a qualitative nominal variable male or female what is true about a frequency distribution that summarizes the data?
