The eigenvalue is a measure of how much of the variance of the observed variables a factor explains. Any factor with an eigenvalue ≥1 explains more variance than a single observed variable, so if the factor for socioeconomic status had an eigenvalue of 2.3 it would explain as much variance as 2.3 of the three variables. This factor, which captures most of the variance in those three variables, could then be used in another analysis. The factors that explain the least amount of variance are generally discarded. How do we determine how many factors are useful to retain?

The price elasticity of demand is a measure of how much the
demand for a product is affected by a change in price. Review the
following scenario and answer the questions that follow.
Evelyn makes $15,000 per year and Tami makes $150,000 per year.
They are both buying roast beef at the grocery store. Evelyn asks
for $10 worth of roast beef, and Tami asks for 10 pounds of roast
beef.
What is each consumer’s price elasticity of demand?

The capacitance of an object is a measure of how much charge separation can be produced...
The capacitance of an object is a
measure of how much charge separation can be produced on the object
by applying a voltage difference to it, or contrarily, how much
voltage arises across the object as a result of a particular charge
separation developing. The equation defining the capacitance is
Q = C ΔV
where Q is the charge
separation (+Q and -Q at two different places on
the capacitor), C is the capacitance, and ΔV is
the potential difference....

How could you define operationally and measure the variables if
Hypothesis: H0: p=0 (there is no linear relationship between
playing video games and aggression). H1: p not equal to 0 (there is
linear relationship between playing video games and
aggression)?

The variance in a production process is an important measure of
the quality of the process. A large variance often signals an
opportunity for improvement in the process by finding ways to
reduce the process variance.
