The Normal Distribution and Normal Curve
CHARACTERISTICS:
symmetric
singlepeaked
bellshaped
area under curve is 1
The Distribution:
completely described by
mean, , and standard
deviation, : N(, )
Describes:
multiple measurements of same quantity

From Areas to Values with Table A
Three steps:
1) Draw the distribution: shade the area of interest, label the mean and
standard deviation and the boundary value of interest
2) Calculate: either use Table A to find the value of z that represents the
area
Measures of Center and Location
mean
median
range
percentiles
Measures of
Spread
IQR
quartiles
Standard
deviation
