In ANOVA, post hoc comparisons are used: a. prior to the calculation to determine if ANOVA is necessary
b. after f - obtained if found to be nonsignificant
c. after f - obtained is found to be significant
d. when we plan on comparing only certain specified pairs of sample means with each other

there is no

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
