millimeter (call milli)
thickness of cell phone
centimeter (cent for wedding)
width of wedding ring
meter (meet at the door)
a doorway is just over 2 meters tall
kilometer in miles (opposite of kill a mile - but same measurements)
1 km equals about 2/3 a mile
gram (you know)

kilogram (kill 2 lbs)
about 2.2 lbs
celcius
zero is freezing, 10 is not. 20 is warm, and 30 is hot
rate of exchange on a graph (exchange y for x)
y2 - y1/ x2 - x1
distribution with single clear peak (just one)
unimodal
distribution with two clear peaks
bimodal
on a graph with few distributions on right is skewed___
right (opposite of what you would think)
on a graph with few distributions on left is skewed___
left (opposite of what you would think)
uniform distribution
when data is spread evenly across range
outlier (outer)
an unexpected value that doesn’t fit any trend or pattern
covariance (co-dependent)
if two variables both increase, it’s a positive covariance. if one increases and one decreases, it’s a negative covariance and they are inversely related
first quantity is called..
independent variable
second quantity is called…
dependent variable
covariance (think co)
relationship between 2 variables
direct variable/variation (directly related)
if both variables increase or decrease
negative variance
if one variable increases, and the other decreases
inversely related
as one variable increases, the other decreases
answer is written as squared (2)
the area
area of a parallelogram (square leaning to one side) (parallel is basically a square)
h x b
area of a trapezoid (pyramid with flat top) (trap half the height times both bees)
1/2 x h x (b1 + b2)
area of a circle
pi x r(2) squared
area of a rhombus (diamond shape) (1/2 rhonda - that’s it)
1/2 x d1 x d2
kilo
