Polysemy (/pəˈlɪsɪmi/ or /ˈpɒlɪsiːmi/; from Greek: πολύ-, polý-, “many” and σῆμα, sêma, “sign”) is the capacity for a word or phrase to have multiple related meanings. Dictionary writers often list polysemes under the same entry; homonyms are defined separately.

When to use one variable or two variable data tables?
Data tables are especially useful when a formula depends on several values, and you’d like to experiment with different combinations of inputs and compare the results. Currently, there exist one variable data table and two variable data table.
When do you need to include multiple dependent variables?
Even if you are primarily interested in the relationship between an independent variable and one primary dependent variable, there are usually several more questions that you can answer easily by including multiple dependent variables. Often a researcher wants to know how an independent variable affects several distinct dependent variables.
When to use multiple measures of independent variables?
This is a measure of the independent variable typically given at the end of the procedure to confirm that it was successfully manipulated. Multiple measures of the same construct can be analyzed separately or combined to produce a single multiple-item measure of that construct.
When to use only one independent variable in multiple linear regression?
In multiple linear regression, it is possible that some of the independent variables are actually correlated with one another, so it is important to check these before developing the regression model. If two independent variables are too highly correlated (r2 > ~0.6), then only one of them should be used in the regression model.
