, Linear Transformation - correct answer-involves adding a constant "a", multiplying by a
constant "b", or both. We can write a linear transformation of the random variable X in
the form Y = a + bX.
Interpret a Z-score - correct answer-
Interpret Standard Deviation - correct answer-Standard Deviation measures spread by
giving the "typical" or "average" distance that the observations (context) are away from
their (context) mean
Marginal vs. Conditional Distributions - correct answer-In a 2-way Table, Marginal
distributions consider only one variable and use the total Row/Column of the table only
Conditional distributions describe the distribution of one variable for a specific value of
the other. (One Row/Column inside the Table)
Percentiles - correct answer-The pth percentile of a list is the smallest number such that
at least p% of the numbers in the list are no larger than it. The pth percentile of a
random variable is the smallest number such that the chance that the random variable
is no larger than it is at least p%.
Using Normalcdf and InvNorm - correct answer-Using boundaries to find Area :
Normcdf(min,max,mean,SD)
Using Area to find boundary
Invnorm(area to the left as a decimal,mean,SD)
How does Shape affect measures of Center - correct answer-Skew Left (Mean<Median)
Skew Right (Mean>Median)
Fairly Symmetric (Mean=Median
