The set of numbers that includes the counting numbers, beginning with 1, is called the set of whole numbers natural numbers integers rational numbers

Counting Numbers - Also called natural numbers, the set of positive numbers used to count objects. 1, 2, 3, 4, 5, ... Integers - The set of numbers including all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero) -- fractions and decimals are not integers.

natural numbers

Step-by-step explanation:

Natural numbers are also known as the counting numbers.  They start at 1 and include all whole numbers from 1 up.

Whole numbers are the counting numbers with 0 added to the set.

Integers are the whole numbers with negatives added to the set.

Rational numbers are all numbers that can be written as fractions, including whole numbers, fractions and decimals.

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
