Munich dunkel is the maltiest style in the BJCP Dark Lager category. It is a beer full of toasted bread and other malt flavors and aromas from the heavy use of melanoidin-rich Munich malt. Most good examples are balanced nearly even, leaning a little to the sweet side, which hides the restrained hop bitterness.
With a two way data table, two categorical variables can be measured and compared. For example, hair color and gender could be measured for a group of individuals. The categorical variables that would be observed and recorded would be whether the person is male or female and what color his or her hair is.
In any given study, you are trying to measure (or evaluate) certain elements that change value depending on certain factors. These are called variables. Think of the word 'vary,' which means 'to change,' and you'll be able to remember variable. Some variables change from person to person. For example, height is a variable because it changes from person to person; if everyone in the world was the same exact height, it wouldn't be a variable. Likewise, IQ varies from person to person, so it is another variable.
