welcome to math with mr. J in this video

I'm going to cover how to find the range

of a data set and the range is the

distance between the lowest valued

number and the highest valued number and

we have two examples that we're going to

go through together in order to get this

down so let's jump right in to number

one so for number one we have a data set

that is out of order so the first thing

we want to do is put it in order from

least to greatest

that's going to help organize us and

also make it much easier to calculate

range once we get to that point so the

first number the lowest valued number

within that set is 2 so I put my 2 then

we have two threes and I'm crossing

those numbers off as I go along that way

I don't miss anything and I don't count

anything twice then we have a five a

seven and eight two nines and lastly a

10 so now we are ready to calculate

range and we do that by finding the

difference between the highest and

lowest values in the set that will give

us our range or distance between our

highest number and lowest number in

value so our highest here is 10 and our

lowest is two so we would do ten minus

two that gives us eight and that is our

range so our range equals eight all

right on to number two here again this

data set is not in order so let's put it

in order from least to greatest and our

least valued number here is 73

then we have an 82 83 85 87 to 90s and

then in 92 and lastly 96 so we take the

difference between the highest and low

lowest values in that set in order to

get the ring so our highest is 96 and

our lowest is 73 so we need to do 96

minus 73 and that will give us our range

or distance between the highest and

lowest values in that set

so 96 minus 73 equals 23 so our range is

23 so there you have it there's how you

find the range of a data set hopefully

that helped thanks so much for watching

until next time peace
