define mode, median and mean
mode: most frequently occurring number
median: the middle number

Range, variance and standard deviation.
Define range
biggest minus smallest
define variance
how far does it spread
define standard deviation
the square root of the variant
define correlation
correlation examines whether there is a relationship between two or more
what is the correlation coefficient
a numerical index of the degree of relationship between two variables. It determines whether a relationship is positive or negative
what is positive correlation
when two or more variables vary in the same pattern
what is negative correlation
when two or more variables show patterns of variation directly opposite one another
