r squared X 100
z score
x-m/sd
z scorxe of x
x=m+(x+sd)
a graph must
start at zero y axis must be labeled with with dv x axis with iv footnotes legend error bars
Type 1 error
finding a significance when their is not one
Type 2 Error
Finding no significance when there really is one

0the number assigned to each subject is 1 (such as a tally
ordinal data
the number assigned to each subject is apart of a ranking (class rank) does not show how much of an item but how it compares to other items.
interval data
the number assigned to each subject tells you how much but measuring can’t start at zero. (scale)
Ratio data
the number assigned to each subject tells you how much but measuring can start at zero. (scal
What type of data is used for parametric test
ratio and interval
