hey everyone welcome to learn algebra

faster in this video we are going to

discuss how to find the mid range of a

set of numbers okay mid range and range

are similar but they're different in the

range remember we first found the

highest number and then we subtracted

the lowest number and what that did for

us was it showed us how much variation

there was from the lowest number to the

highest number but in mid range there's

a key difference we want to find the

middle of the range which means we want

to find the average between the highest

and the lowest so we will still have to

identify the highest number we'll also

have to identify the lowest number but

instead of subtracting the two we want

to find the average so we need to add

them and divide by two now this will

give us the number that's in the middle

of the highest number and the lowest

number so we don't necessarily have to

put all the numbers in order and the way

I like to find the highest and the

lowest is I just read the numbers left

to right and Mark mark the highest as

they get higher and the lowest as they

get lower so we see we start with 10 16

is bigger than 10 19 is bigger than 16

21 is bigger than 19 so 21 is our new

highest value so not 13 not 16 okay 25

is even higher and 29 is even higher

than that and as we continue to read

left to right we find out that 29 is our

highest number so we will go ahead and

write it down

okay let's start from the left ten is

our lowest and as we are reading we find

another ten but as we're reading left to

right we actually do not find any number

that is lower than ten so we find out

ten is the lowest now we want to find

the average between these two points and

that's our mid-range so we need to add

them and divide by two twenty nine plus

ten is thirty nine and thirty nine

divided by two actually gives us

nineteen point five so our mid-range

value is nineteen point five let's go

ahead and check another practice problem

okay for this number remember mid-range

means we need to find the average

between the highest and the lowest okay

57 is a big number 43 is less 65 is even

bigger 65 is repeated so we find out as

we read left to right that 65 is our

highest number so we will write it down

now let's find our lowest number 43 is

lower than 57 39 is even lower and it

looks like 39 is our lowest number so we

have 65 plus 39 divided by 2 will be our

mid-range so 65 plus 39 gives us 104 and

when we divide 104 by 2 we get our

mid-range which is 52 so notice on the

mid-range we didn't necessarily have to

put the whole set of numbers in order we

just used a little method to find the

highest number and the lowest number and

remember the difference between

mid-range and range is in mid range we

find the average and in range you just

find the difference so if you want to

get this in much more head over to learn

algebra faster calm we have a free video

course for you and you'll find a whole

lot more on mean median mode range and

mid range and much more thanks and I'll

catch you in the next video
