b. Expresses the arithmetic average of a frequency distribution
c. Indicates the typical value of a frequency distribution
d. Represents the midpoint of a frequency distribution

i. Indicates how widely the out around the measures of central tendency
j. Measure an event over time

B. Match the following data display tools with their descriptions. (Descriptions may be used more than once or not at all.)
A horizontal or vertical arrangement of rectangular shapes that represents data from one or more groups or categories
b. An orderly arrangement of values that displays data in rows and columns
c. An arrangement of pieces in a circular shape that represents the component parts of a single group or variable
d. An arrangement of lines that represents one or more frequency distributions
e. An arrangement of rectangular shapes that represents distributions of continuous variables

Enter man caves. Whether we're building a boat, playing computer games, reading car magazines, listening to loud music, working on a motorcycle, or watching action movies or five sports games at once, man caves serve a basic psychological function, even if the guy is aware of it or not. And it's especially vital if the guy's emotional needs aren’t being met in other spaces. (Sorry, honey, but that fake moss inside a cloche is doing nothing for me.)

“It’s a way of saying, ‘I love my family and flowers, but that’s not what I need to regulate my emotions,’” Gosling says. “Man caves are the architectural equivalent to hanging out with your mates."

So you see? We are fragile emotional beings. We just need a kegerator (a refrigerator for a keg of beer) and power tools to cope.

When it comes to designing and outfitting a man cave, Gosling says it's extremely important that there is no compromise. (Shall I repeat that, ladies? No compromise!)

That's because a space that properly satisfies and regulates emotional and psychological needs is much less likely to evolve if someone else influences the outcome.
